C#实现FTP传送文件的示例
简介:
接上文实现对FTP的传送文件,此文和上文可以说是如出一辙,不过此文是通过cmd进行建立连接的,建立连接后也是通过以下几个步骤实现操作。建立文件的层级结构如上文,这里就不啰嗦了。C#实现FTP上传资料
1.主方法进行调用:
this.ftpOperation.UploadFile(vIMSPath, vUID, vPassword, vLocalPath + "/" + txtFile, txtFile);
2.ftpOperation.cs 文件中的实现操作方法
2.1 主方法中调用的方法:
public void UploadFile(string vPath, string vUID, string vPassword, string vLocalPath, string file)
{
bool status = false;
//
status = connectState(vPath, vUID, vPassword);//通过cmd进行建立连接
if (status)
{
DirectoryInfo theFolder = new DirectoryInfo(vPath + "/" + file);
string filename = vLocalPath;
Transport(vLocalPath, vPath + "/" + file);//传送文件
System.Diagnostics.Process.Start(vPath);
}
else
{
MessageBox.Show("未能连接!");
}
}
2.2 通过调用cmd进行建立连接:
public static bool connectState(string vPath, string vUID, string vPassword)
{
bool Flag = false;
Process proc = new Process();
try
{
proc.StartInfo.FileName = "cmd.exe";
proc.StartInfo.UseShellExecute = false;
proc.StartInfo.RedirectStandardInput = true;
proc.StartInfo.RedirectStandardOutput = true;
proc.StartInfo.RedirectStandardError = true;
proc.StartInfo.CreateNoWindow = true;
proc.Start();
string dosLine = "net use " + vPath + " " + vPassword + "/user:" + vUID;
proc.StandardInput.WriteLine(dosLine);
proc.StandardInput.WriteLine("exit");
while (!proc.HasExited)
{
proc.WaitForExit(1000);
}
string errormsg = proc.StandardError.ReadToEnd();
proc.StandardError.Close();
if (string.IsNullOrEmpty(errormsg))
{
Flag = true;
}
else
{
throw new Exception(errormsg);
}
}
catch (Exception ex)
{
//throw ex;
MessageBox.Show(ex.Message);
}
finally
{
proc.Close();
proc.Dispose();
}
return Flag;
}
2.3 传送文件:
public static void Transport(string src, string fileName)
{
FileStream inFileStream = new FileStream(src, FileMode.Open);
//if (!Directory.Exists(dst))
//{
// Directory.Move(src,dst);
//}
FileStream outFileStream = new FileStream(fileName, FileMode.OpenOrCreate);
byte[] buf = new byte[inFileStream.Length];
int byteCount;
while ((byteCount = inFileStream.Read(buf, 0, buf.Length)) > 0)
{
outFileStream.Write(buf, 0, byteCount);
}
inFileStream.Flush();
inFileStream.Close();
outFileStream.Flush();
outFileStream.Close();
File.Delete(src);//删除本地文件
}
