最近用到的觉得比较不错的几个tips－（1）asp。net操作ftp，上传和下载 （2） 长时间提交，在提交后禁止页面按钮 （3） 方便的javascript日历

工作换了，也不专门搞代码了，blog也少了，不过最近项目中有用到几个不错的tips觉得还是写下比较好，各位看不懂别见怪，是给自己看的

1、首先就是在web程序中上传文件到ftp并且下载，感觉这个类还是不错的：
上传：

private string Upload(HttpPostedFile pf,string ExtName)
        {
            FtpSupport.FtpConnection ftp=new FtpSupport.FtpConnection();
            System.IO.Stream fs=pf.InputStream;
            string FileName=DateTime.Now.ToString("yyyyMMddhhmmss");
            FileName+="."+ExtName;
            ftp.Connect(ConfigurationSettings.AppSettings["FtpIP"].ToString(),ConfigurationSettings.AppSettings["FtpUserName"].ToString(),ConfigurationSettings.AppSettings["FtpPassWord"].ToString());
            ftp.SetCurrentDirectory("/");
            ftp.PutStream(fs,FileName);                
            fs.Close();
            ftp.Close();
            return FileName;
        }

ftpsupport.dll：下载

当下载的时候：
 

    private void FtpDown(string filename)
        {
            FtpSupport.FtpConnection ftp=new FtpSupport.FtpConnection();;
            try
            {
                ftp.Connect(ConfigurationSettings.AppSettings["FtpIP"].ToString(),ConfigurationSettings.AppSettings["FtpUserName"].ToString(),ConfigurationSettings.AppSettings["FtpPassWord"].ToString());
                try
                {
                    ftp.SetCurrentDirectory("/");            
                    if(ftp.FileExist(filename)&&filename!="")
                    {
                        Response.Write("<script>window.open('ftp://"+Server.UrlEncode(ConfigurationSettings.AppSettings["FtpUserName"].ToString())+":"+ConfigurationSettings.AppSettings["FtpPassWord"].ToString()+"@"+ConfigurationSettings.AppSettings["FtpIP"].ToString()+"/"+filename+"')</script>");
                    }
                    else
                    {
                        ClsOper.Alert("Can Not Find File");
                    }
                }
                catch
                {
                    ClsOper.Alert("Can Not Operate FTP");
                }
                finally
                {
                    ftp.Close();
                }
            }
            catch
            {
                ClsOper.Alert("Can Not Connect FTP");
            }
        
        }

当然要删除就是：ftp.DeleteFile

不过提行一点就是因为下载是用url形式出现在地址栏的所以密码和用户名只能是 字母、数字或者'_' '-' '+' 其他特殊字符比如 @#$%&都不行

ok，有人说不想暴露ftp帐号和下载文件名，那么只有直接response了，结合我以前的文章《通过注册表得到文件的ContentType》，解决办法如下：

string filename="b.rar";
            string fileextname=filename.Split('.')[filename.Split('.').Length-1];
            string DEFAULT_CONTENT_TYPE = "application/unknown";
            RegistryKey regkey,fileextkey;
            string filecontenttype;
            try 
            {                
                regkey=Registry.ClassesRoot;                
                fileextkey=regkey.OpenSubKey(fileextname);                
                filecontenttype=fileextkey.GetValue("Content Type",DEFAULT_CONTENT_TYPE).ToString();
            }
            catch
            {
                filecontenttype=DEFAULT_CONTENT_TYPE;
            }        
            Response.Clear();
            Response.AddHeader("Content-Disposition", "attachment; filename=" + Server.UrlEncode(filename)); 
            Response.ContentType=filecontenttype;
            
            FtpSupport.FtpConnection conn=new FtpSupport.FtpConnection("localhost","用户名","密码");
            conn.SetCurrentDirectory("/");
            if(conn.FileExist(filename))
            {
                FtpSupport.FtpStream ftpfs=conn.OpenFile(filename,FtpSupport.GenericRights.Read);
                byte [] buffer=new byte[10240];
                int n=ftpfs.Read(buffer,0,buffer.Length);
                while(n>0)
                {
                    Response.BinaryWrite(buffer);
                    n=ftpfs.Read(buffer,0,buffer.Length);
                }
                ftpfs.Close();
                
            }
        }

当然还需要using Microsoft.Win32;

2、在提交的时候过程很长，为了防止用户再次点击而且为了界面友好可以用一个层遮住所有按钮再显示个提示信息，等服务器端处理完成再导航到本页（location.href='地址'）就可以：

<div id="doing" runat="server" style="Z-INDEX: 12000; LEFT: 0px; VISIBILITY: hidden; WIDTH: 100%;  POSITION: absolute; TOP: 300px; HEIGHT: 100%">
                <table width="100%" height="100%">
                    <tr align="center" valign="middle">
                        <td>
                            <table width="169" class="font3" height="62" bgcolor="#6699ff" style="FILTER: Alpha(Opacity=75); WIDTH: 169px; HEIGHT: 62px">
                                <tr align="center" valign="middle">
                                    <td>页面提交中,请等待<br>
                                        Please wait
                                    </td>
                                </tr>
                            </table>
                        </td>
                    </tr>
                </table>
            </div>

pageload里面这么写：this.Button1.Attributes.Add("onclick","document.getElementById('doing').style.visibility='visible';");
，等操作结束重定向了后页面重新加载一次，这个层也就消失了。。。

3、这个日历也不错，自己做了下修改：

用的时候先：

<SCRIPT src="calendar.js"></SCRIPT>

然后使用：

<INPUT onclick="setday(this,document.all.tb_CheckInDate)" type="button" value="Select">

这里的tb_checkindate就是把选择的日期输入到文本框的id
