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

}
