C # how to upload the file to the specified address in the server

This article mainly introduces the relevant knowledge of how C# uploads files to the designated address in the server, the content is detailed and easy to understand, the operation is simple and fast, and has a certain reference value. I believe you will gain something after reading this article on how to upload files to the server at the designated address. Let's take a look.

First, establish a connection public string connectFTP (string vPath, string vUID, string vPassword) {string errormsg = ""; 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);} errormsg = proc.StandardError.ReadToEnd (); proc.StandardError.Close ();} catch (Exception ex) {/ / throw ex / / MessageBox.Show (ex.Message);} finally {proc.Close (); proc.Dispose ();} return errormsg Upload file public void UploadFile (string vPath, string vUID, string vPassword, string vLocalPath, string file) {bool status = false; status = connectState (vPath, vUID, vPassword); if (status) {DirectoryInfo theFolder = new DirectoryInfo (vPath + "/" + file); string filename = vLocalPath Transport (vLocalPath, vPath + "/" + file); / / System.Diagnostics.Process.Start (vPath);} else {mesLog.Info ("failed to connect!"); / / MessageBox.Show ("failed to connect!") Connection status 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;} IV. Transfer public static void Transport (string src, string fileName) {FileStream inFileStream = new FileStream (src, FileMode.Open) 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);} this is the end of the article on "how to upload files to the specified address on the server".
