读写网上邻居共享的文件夹，和操作本地文件夹类似，只要有权限读取写入即可。
分为以下2步：
1.打通共享文件夹权限
2.操作文件
打通共享文件夹权限
1 /// <summary> 2 /// 连接共享文件 3 /// </summary> 4 /// <param name="path">共享文件地址</param> 5 /// <param name="userName">用户名</param> 6 /// <param name="passWord">密码</param> 7 /// <returns>true:连接成功 false:连接失败</returns> 8 public static bool ConnectState(string path, string userName, string passWord) 9 { 10 bool Flag = false; 11 Process proc = new Process(); 12 try 13 { 14 proc.StartInfo.FileName = "cmd.exe"; 15 proc.StartInfo.UseShellExecute = false; 16 proc.StartInfo.RedirectStandardInput = true; 17 proc.StartInfo.RedirectStandardOutput = true; 18 proc.StartInfo.RedirectStandardError = true; 19 proc.StartInfo.CreateNoWindow = true; 20 proc.Start(); 21 string dosLine = @"net use " + path + " /User:" + userName + " " + passWord + " /PERSISTENT:YES"; 22 proc.StandardInput.WriteLine(dosLine); 23 proc.StandardInput.WriteLine("exit"); 24 while (!proc.HasExited) 25 { 26 proc.WaitForExit(1000); 27 } 28 string errormsg = proc.StandardError.ReadToEnd(); 29 proc.StandardError.Close(); 30 if (string.IsNullOrEmpty(errormsg)) 31 { 32 Flag = true; 33 } 34 else 35 { 36 throw new Exception(errormsg); 37 } 38 } 39 catch (Exception ex) 40 { 41 throw ex; 42 } 43 finally 44 { 45 proc.Close(); 46 proc.Dispose(); 47 } 48 49 return Flag; 50 }
创建文件夹
1 DirectoryInfo dirInfo = new DirectoryInfo("\\WIN-R3377JMR1LG\ShareFolder"); 2 if (dirInfo.Exists == false) 3 { 4 dirInfo.Create(); 5 }
上传文件
1 /// <summary> 2 /// 上传文件到共享文件夹 3 /// </summary> 4 /// <param name="sourceFile">本地文件</param> 5 /// <param name="remoteFile">远程文件</param> 6 public static void UpLoadFile(string sourceFile, string remoteFile) 7 { 8 //判断文件夹是否存在 ->不存在则创建 9 var targetFolder = Path.GetDirectoryName(remoteFile); 10 DirectoryInfo theFolder = new DirectoryInfo(targetFolder); 11 if (theFolder.Exists == false) 12 { 13 theFolder.Create(); 14 } 15 16 try 17 { 18 WebClient myWebClient = new WebClient(); 19 NetworkCredential cread = new NetworkCredential(); 20 myWebClient.Credentials = cread; 21 22 using (FileStream fs = new FileStream(sourceFile, FileMode.Open, FileAccess.Read)) 23 { 24 using (BinaryReader r = new BinaryReader(fs)) 25 { 26 byte[] postArray = r.ReadBytes((int)fs.Length); 27 using (Stream postStream = myWebClient.OpenWrite(remoteFile)) 28 { 29 if (postStream.CanWrite == false) 30 { 31 LogUtil.Error($"{remoteFile} 文件不允许写入~"); 32 return; 33 } 34 35 postStream.Write(postArray, 0, postArray.Length); 36 } 37 } 38 } 39 } 40 catch (Exception ex) 41 { 42 string errMsg = $"{remoteFile} ex:{ex.ToString()}"; 43 LogUtil.Error(errMsg); 44 Console.WriteLine(errMsg); 45 } 46 }
