一：文件读取
filestream读取：
public void reader()
{
string s = "";
FileStream file = new FileStream(@"d://shop_category[1].txt", FileMode.Open);
StreamReader reader = new StreamReader(file,Encoding.Default);
while (reader.ReadLine() != null)
{
s += reader.ReadLine();
}
Console.WriteLine(s);
}
StreamReader
public void read()
{
FileStream file = new FileStream(@"d:\\sa.txt", FileMode.Open);
byte[] bt = new byte[file.Length];
file.Read(bt, 0, bt.Length);
string str = Encoding.Default.GetString(bt);
conso.writeline(str);
}
public void read()
{
string s = File.ReadAllText(@"d://shop_category[1].txt",Encoding.Default);
Console.WriteLine(s);
}
======================================================================
二：文件写入
public void writer()
{
string s="hello word";
FileStream write = new FileStream(@"d://aasdaaaaaa.txt", FileMode.Create);
StreamWriter writer = new StreamWriter(write, Encoding.Default);
writer.Write(s);
Console.WriteLine(s);
}
将文字写入sa.txt
public void writer()
{
string s="hello word";
File.WriteAllText(@"d://sa",s);
}
/// <summary>
/// 用FileStream写文件
/// </summary>
/// <param name="str"></param>
/// <returns></returns>
public void FileStreamWriteFile(string str)
{
byte[] byData;
char[] charData;
try
{
FileStream nFile = new FileStream("love.txt", FileMode.Create);
//获得字符数组
charData = str.ToCharArray();
//初始化字节数组
byData = new byte[charData.Length];
//将字符数组转换为正确的字节格式
Encoder enc = Encoding.UTF8.GetEncoder();
enc.GetBytes(charData, 0, charData.Length,byData,0,true);
nFile.Seek(0, SeekOrigin.Begin);
nFile.Write(byData, 0, byData.Length);
}
catch (Exception ex)
{
throw ex;
}
}
===============================================================
filesteam 读取
FileStream filestream = new FileStream(m_filepath, FileMode.Open, FileAccess.Read);
StreamReader objStreamReader = new StreamReader(filestream);
while (objStreamReader.Peek()>=0)
{
string sLine = objStreamReader.ReadLine();//读取一行
//可以将内容读到 ArrayList 中。
}
objStreamReader.Close();
filestream.Close();
FileStream file = new FileStream(@"d:\\sa.txt", FileMode.Open); //读取sa.txt文件
byte[] bt = new byte[file.Length];
file.Read(bt, 0, bt.Length); //转换为字节读取
string str = Encoding.Default.GetString(bt); //读到内存str中（可设置编码）
