在C#里怎么实现：windows访问(读取)linux上的文件？

利用psftp.exe可以在dos界面下，实现linux文件的上传和下载。
还可以通过调用Process的命令方式，实现上传文件到linux上,
但是实现文件下载到windows时，就不行。下面是下载时的源代码
而同样的upload时，是可以的，不知道为什么会这样：

#region Download

// Upload the files
// output of the plugin during its running in console
public string Download()
　　 {
　　 string outPutMessage = "";
　　 string scriptLocation = "";

//Create Script File
　　 scriptLocation = this.CreateScriptFile();
　　
　　 //Run the Upload event
　　 ProcessStartInfo processInfo = new ProcessStartInfo();

　　 //Set the Shell Command(the plugins' path)
　　 processInfo.FileName = this.m_ShellCommand;

　　 //Don't show console window
　　 processInfo.CreateNoWindow = true;

　　 //don't use shell to execute this script
　　 processInfo.UseShellExecute = false;

　　 //Open Process Error Output
　　 processInfo.RedirectStandardError = true;

　　 //Open Process Input
　　 processInfo.RedirectStandardInput = true;

　　 //Open Process Output
　　 processInfo.RedirectStandardOutput = true;

　　 //Get process arguments
　　 string arguments = "";

arguments += this.m_UserID + "@" + this.m_ServerName + " "; //Login Server with specified userid
arguments += "-pw " + this.m_Password + " "; //Login with specified password
arguments += "-P " + this.m_Port + " "; //Connect to specified port
arguments += "-b " + scriptLocation + " "; //use specified batchfile
arguments += "-be"; //don't stop batchfile processing if errors
processInfo.Arguments = arguments;

　　 //Create new Process
　　 Process process = new Process();
　　 try
　　 {
　　 process.StartInfo = processInfo;
　　 Boolean b = process.Start();

　　 //Input "y" for the psftp's first login prompt
　　 //Just for the security information
process.StandardInput.WriteLine("y");

　　 //Get the return message from process(Error and Output information)
　　 //This message will be logged to file for debug!　　
　　 outPutMessage += process.StandardError.ReadToEnd();

　　 //Wait for the process exit
　　 process.WaitForExit();

　　 //Close all the modules opened
　　 process.Close();
　　 process.Dispose();

　　 //Delete the script file OK
　　 File.Delete(scriptLocation);

　　 return outPutMessage;
　　 }
catch(Exception ex)
　　 {
　　 process.Dispose();
　　 //Delete the script file
　　 File.Delete(scriptLocation);
　　 throw new Exception("Error occured during upload file to remote server!",ex);
　　 }
　　 }

　　 #endregion

　　 #region CreateScriptFile

　　 /// Create Batch Script File
private string CreateScriptFile()
{
StreamWriter fileStream;
string scriptLocation = "";

//Get the Batch Script to execute
StringBuilder sbdScript = new StringBuilder();

//Redirect to the default remote location
sbdScript.Append(" cd " + this.m_RemoteLocation + Environment.NewLine);


//Upload files
//foreach(object file in this.m_UploadFiles)
//{
sbdScript.Append(" get " + this.m_DownloadFiles + Environment.NewLine);
//}

//Close the session
sbdScript.Append(" quit ");

//Save the Script to templocation
scriptLocation = this.m_TempLocation + @"" + System.Guid.NewGuid().ToString() + ".bat";

try
{
fileStream = new StreamWriter(scriptLocation);
fileStream.Write(sbdScript.ToString());
fileStream.Close();
}
catch (Exception ex)
{
fileStream = null;
throw new Exception("Error occured during create script file!", ex);
}

return scriptLocation;
}
