这篇文章介绍了C#实现FTP上传文件的方法，文中通过示例代码介绍的非常详细。对大家的学习或工作具有一定的参考借鉴价值，需要的朋友可以参考下
1.通过用FTP进行上传文件，首先要实现建立FTP连接，一般建立FTP连接，需要知道FTP配置有关的信息。一般要在Bean中建立一个ServiceFileInfo.cs文件进行记录，一般需要FTP地址、登录用户名和登录密码。然后通过其他页面进行访问读取。代码样式如下：
class ServiceFileInfo { // service1 public static string txtFilePath = @"ftp://12.128.128.01/FileName/"; //userid & password public static string txtUID = "username"; public static string txtPWD = "password"; }2.通过主方法读取Bean文件下面的的ServiceFileInfo.cs文件的信息，去实现建立FTP连接。这里还需要清楚的知道你上传文件的路径(Path)和文件名称(FileName)。根据这些信息主方法去调用写着Bean中的另外一个ftpOperation.cs 文件(这个.cs文件中主要写一些关于FTP的操作方法)，进行FTP访问操作。
- 主方法调用FTP操作代码
ExecutionResult exeRes = this.ftpOperation.UploadFile(textFilePath, txtUID, txtPWD, Path + "/" + FileName + ".txt");//.txt为文件的后缀名
- Bean文件中ftpOperation.cs文件关于FTP操作的方法
public ExecutionResult UploadFile(string vIMSPath, string vUID, string vPassword, string vLocalPath) { ExecutionResult result = new ExecutionResult(); result = connectState(vIMSPath, vUID, vPassword, vLocalPath);//调用下面代码方法 if (result.Status) { File.Delete(vLocalPath); } return result; }connectState()方法
public static ExecutionResult connectState(string vIMSPath, string vUID, string vPassword, string fileName) { string operater = ""; bool Flag = false; ExecutionResult result; result = new ExecutionResult(); lock (lockObj) { try { operater = "Connet to FTP"; FTPOperation ftp = new FTPOperation(new Uri(vIMSPath), vUID, vPassword); operater = "Upload file"; Flag = ftp.UploadFile(fileName, Path.GetFileName(fileName), true); if (Flag) { result.Status = true; result.Message = "Send to server OK"; } } catch (Exception ex) { result.Status = false; result.Anything = "Mail"; result.Message = operater + ":" + ex.Message; } } return result; }- UploadFile()方法
public bool UploadFile(string LocalFullPath, string RemoteFileName, bool OverWriteRemoteFile) { bool result; try { bool flag = !this.IsValidFileChars(RemoteFileName) || !this.IsValidFileChars(Path.GetFileName(LocalFullPath)) || !this.IsValidPathChars(Path.GetDirectoryName(LocalFullPath)); if (flag) { throw new Exception("非法文件名或目录名!"); } bool flag2 = File.Exists(LocalFullPath); if (!flag2) { throw new Exception("本地文件不存在!"); } FileStream fileStream = new FileStream(LocalFullPath, FileMode.Open, FileAccess.Read); byte[] array = new byte[fileStream.Length]; fileStream.Read(array, 0, (int)fileStream.Length); fileStream.Close(); result = this.UploadFile(array, RemoteFileName, OverWriteRemoteFile); } catch (Exception ex) { this.ErrorMsg = ex.ToString(); throw ex; } return result; } public bool UploadFile(byte[] FileBytes, string RemoteFileName) { bool flag = !this.IsValidFileChars(RemoteFileName); if (flag) { throw new Exception("非法文件名或目录名!"); } return this.UploadFile(FileBytes, RemoteFileName, false); } public bool UploadFile(byte[] FileBytes, string RemoteFileName, bool OverWriteRemoteFile) { bool result; try { bool flag = !this.IsValidFileChars(RemoteFileName); if (flag) { throw new Exception("非法文件名！"); } bool flag2 = !OverWriteRemoteFile && this.FileExist(RemoteFileName); if (flag2) { throw new Exception("FTP服务上面已经存在同名文件！"); } this.Response = this.Open(new Uri(this.Uri.ToString() + RemoteFileName), "STOR"); Stream requestStream = this.Request.GetRequestStream(); MemoryStream memoryStream = new MemoryStream(FileBytes); byte[] array = new byte[1024]; int num = 0; for (;;) { int num2 = memoryStream.Read(array, 0, array.Length); bool flag3 = num2 == 0; if (flag3) { break; } num += num2; requestStream.Write(array, 0, num2); } requestStream.Close(); this.Response = (FtpWebResponse)this.Request.GetResponse(); memoryStream.Close(); memoryStream.Dispose(); FileBytes = null; result = true; } catch (Exception ex) { this.ErrorMsg = ex.ToString(); throw ex; } return result; }到此这篇关于C#实现FTP上传文件的文章就介绍到这了。希望对大家的学习有所帮助，也希望大家多多支持0133技术站。
