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。
ExecutionResult exeRes = this.ftpOperation.UploadFile(textFilePath, txtUID, txtPWD, Path + "/" + FileName + ".txt");//.txt为文件的后缀名
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;
}
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;
}
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!");

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;

break;
}
