【转】c#文件操作大全（一）

1.创建文件夹
//using System.IO;
Directory.CreateDirectory(%%1);

2.创建文件
//using System.IO;
File.Create(%%1);

3.删除文件
//using System.IO;
File.Delete(%%1);

4.删除文件夹
//using System.IO;
Directory.Delete(%%1);

5.删除一个目录下所有的文件夹
//using System.IO;
foreach (string dirStr in Directory.GetDirectories(%%1))
{
 DirectoryInfo dir = new DirectoryInfo(dirStr);
 ArrayList folders=new ArrayList();
 FileSystemInfo[] fileArr = dir.GetFileSystemInfos();
 for (int i = 0; i < folders.Count; i++)
 {
  FileInfo f = folders[i] as FileInfo;
  if (f == null)
  {
   DirectoryInfo d = folders[i] as DirectoryInfo;
   d.Delete();
  }
 }
}

6.清空文件夹
//using System.IO;
Directory.Delete(%%1,true);
Directory.CreateDirectory(%%1);

7.读取文件
//using System.IO;
StreamReader s = File.OpenText(%%1);
string %%2 = null;
while ((%%2 = s.ReadLine()) != null){
 %%3
}
s.Close();

8.写入文件
//using System.IO;
FileInfo f = new FileInfo(%%1);
StreamWriter w = f.CreateText();
w.WriteLine(%%2);
w.Close();

9.写入随机文件
//using System.IO;
byte[] dataArray = new byte[100000];//new Random().NextBytes(dataArray);
using(FileStream FileStream = new FileStream(%%1, FileMode.Create)){
// Write the data to the file, byte by byte.
 for(int i = 0; i < dataArray.Length; i++){
  FileStream.WriteByte(dataArray[i]);
 }
// Set the stream position to the beginning of the file.
 FileStream.Seek(0, SeekOrigin.Begin);
// Read and verify the data.
 for(int i = 0; i < FileStream.Length; i++){
  if(dataArray[i] != FileStream.ReadByte()){
   //写入数据错误
   return;
  }
 }
//"数据流"+FileStream.Name+"已验证"
}

10.读取文件属性
//using System.IO;
FileInfo f = new FileInfo(%%1);//f.CreationTime,f.FullName
if((f.Attributes & FileAttributes.ReadOnly) != 0){
 %%2
}
else{
 %%3
}

11.写入属性
//using System.IO;
FileInfo f = new FileInfo(%%1);
//设置只读
f.Attributes = myFile.Attributes | FileAttributes.ReadOnly;
//设置可写
f.Attributes = myFile.Attributes & ~FileAttributes.ReadOnly;

12.枚举一个文件夹中的所有文件夹
//using System.IO;
foreach (string %%2 in Directory.GetDirectories(%%1)){
 %%3
}

13.复制文件夹

                        {
                            Folders.Enqueue(fi);
                        }
                    }
                    else
                    {
                        f.CopyTo(f.FullName.Replace(parent, path));
                    }
}

14.复制目录下所有的文件夹到另一个文件夹下

DirectoryInfo d = new DirectoryInfo(%%1);
foreach (DirectoryInfo dirs in d.GetDirectories())
{
    Queue<FileSystemInfo> al = new Queue<FileSystemInfo>(dirs.GetFileSystemInfos());
    while (al.Count > 0)

                        }
                        dirdir.Delete(true);
                    }
                }

17.以一个文件夹的框架在另一个目录创建文件夹和空文件

bool b=false;
string path = (%%2.LastIndexOf("") == %%2.Length - 1) ? %%2 : %%2 + "";
string parent = Path.GetDirectoryName(%%1);
Directory.CreateDirectory(path + Path.GetFileName(%%1));
DirectoryInfo dir = new DirectoryInfo((%%1.LastIndexOf("") == %%1.Length - 1) ? %%1 : %%1 + "");
FileSystemInfo[] fileArr = dir.GetFileSystemInfos();
Queue<FileSystemInfo> Folders = new Queue<FileSystemInfo>(dir.GetFileSystemInfos());
while (Folders.Count > 0)
{
    FileSystemInfo tmp = Folders.Dequeue();
    FileInfo f = tmp as FileInfo;
    if (f == null)
    {
        DirectoryInfo d = tmp as DirectoryInfo;
        Directory.CreateDirectory(d.FullName.Replace((parent.LastIndexOf("") == parent.Length - 1) ? parent : parent + "", path));
        foreach (FileSystemInfo fi in d.GetFileSystemInfos())
        {
            Folders.Enqueue(fi);
        }
    }
    else
    {
        if(b) File.Create(f.FullName.Replace(parent, path));
    }
}

18.复制文件
//using System.IO;
File.Copy(%%1,%%2);

19.复制一个文件夹下所有的文件到另一个目录

  }
  foreach(DirectoryInfo   dir   in   dirc.GetDirectories())   { 
   return   GetFile(fileName,dir.FullName); 
  }
  return   "找不到指定的文件"; 
 }

28.打开对话框

46.Grep

//Traditionally grep stands for "Global Regular Expression Print".
//Global means that an entire file is searched.
//Regular Expression means that a regular expression string is used to establish a search pattern.
//Print means that the command will display its findings.
//Simply put, grep searches an entire file for the pattern you want and displays its findings.
//
//The use syntax is different from the traditional Unix syntax, I prefer a syntax similar to
//csc, the C# compiler.
//
// grep [/h|/H] - Usage Help
//
// grep [/c] [/i] [/l] [/n] [/r] /E:reg_exp /F:files
//
// /c - print a count of matching lines for each input file;
// /i - ignore case in pattern;
// /l - print just files (scanning will stop on first match);
// /n - prefix each line of output with line number;
// /r - recursive search in subdirectories;
//
// /E:reg_exp - the Regular Expression used as search pattern. The Regular Expression can be delimited by
// quotes like "..." and '...' if you want to include in it leading or trailing blanks;
//
// /F:files - the list of input files. The files can be separated by commas as in /F:file1,file2,file3
//and wildcards can be used for their specification as in /F:*file?.txt;
//
//Example:
//
// grep /c /n /r /E:" C Sharp " /F:*.cs

 IDataObject iData = Clipboard.GetDataObject();
 string %%1;
   // 将数据与指定的格式进行匹配，返回bool
   if (iData.GetDataPresent(DataFormats.Text))
   {
    // GetData检索数据并指定一个格式
    %%1 = (string)iData.GetData(DataFormats.Text);
   }
   else
   {
    MessageBox.Show("目前剪贴板中数据不可转换为文本","错误");
   }

57.获取文件路径的父路径
//using System.IO;
string %%2=Directory.GetParent(%%1);

58.创建快捷方式
//首先添加以下引用：COM下Windows Script. Host Object Model，然后可以通过以下方法创建快捷方式。

string app = %%1;"http://localhost/TrainManage/Default.aspx"
string location1 = System.Environment.GetFolderPath(System.Environment.SpecialFolder.Favorites) + "\培训教学教务管理系统.url";
string location2 = System.Environment.GetFolderPath(System.Environment.SpecialFolder.DesktopDirectory) + "\培训教学教务管理系统.url";
string location3 = System.Environment.GetFolderPath(System.Environment.SpecialFolder.Programs) + "\培训教学教务管理系统.url";
try {
  // Create a Windows Script. Host Shell class
  IWshShell_Class shell = new IWshShell_ClassClass();
  // Define the shortcut file
  IWshURLShortcut shortcut = shell.CreateShortcut(location1) as IWshURLShortcut;
  shortcut.TargetPath = app;
  // Save it
  shortcut.Save();
  shortcut = shell.CreateShortcut(location2) as IWshURLShortcut;shortcut.TargetPath = app;
                   // Save it
                   shortcut.Save();
                   shortcut = shell.CreateShortcut(location3) as IWshURLShortcut;
                   shortcut.TargetPath = app;
                   // Save it
                   shortcut.Save();
              }
              catch(COMException ex)
              {
 Console.WriteLine(ex.Message);
}

59.弹出快捷菜单
//在工具箱中找到ContextMenuStrip控件，并拖放至Form1窗体
//设计菜单内容
//将contextMenuStrip1与窗体关联。方法是先选定Form1，为其ContextMenuStrip属性设置属性值为contextMenuStrip1

60.文件夹复制到整合操作

            FolderDialog aa = new FolderDialog();
            aa.DisplayDialog();
            if (aa.Path != "")
            {
                string path = (aa.Path.LastIndexOf("") == aa.Path.Length - 1) ? aa.Path : aa.Path+"";
                string parent = Path.GetDirectoryName(%%1);
                Directory.CreateDirectory(path + Path.GetFileName(%%1));
                %%1 = (%%1.LastIndexOf("") == %%1.Length - 1) ? %%1 : %%1 + "";
                DirectoryInfo dir = new DirectoryInfo(%%1);
                FileSystemInfo[] fileArr = dir.GetFileSystemInfos();
                Queue<FileSystemInfo> Folders = new Queue<FileSystemInfo>(dir.GetFileSystemInfos());
                while (Folders.Count>0)
                {
                    FileSystemInfo tmp = Folders.Dequeue();
                    FileInfo f = tmp as FileInfo;
                    if (f == null)
                    {
                        DirectoryInfo d = tmp as DirectoryInfo;
                        Directory.CreateDirectory(d.FullName.Replace((parent.LastIndexOf("") == parent.Length - 1) ? parent : parent + "", path));
                        foreach (FileSystemInfo fi in d.GetFileSystemInfos())
                        {
                            Folders.Enqueue(fi);
                        }
                    }
                    else
                    {
                        f.CopyTo(f.FullName.Replace(parent, path));
                    }
                }
            }
