//Create a WebRequest object FtpWebRequest request = (FtpWebRequest)WebRequest.Create(ftpServerAddress + "/" + targetFolderPath + "/" + Path.GetFileName(sourceFilePath)); request.Method = WebRequestMethods.Ftp.UploadFile; //Set username and password for the request request.Credentials = new NetworkCredential(ftpUsername, ftpPassword); //Read the file into a byte array byte[] fileContents; using (StreamReader sourceStream = new StreamReader(FullName)) { fileContents = Encoding.UTF8.GetBytes(sourceStream.ReadToEnd()); } //Set the content length of the file request.ContentLength = fileContents.Length; //Write the file to the request stream using (Stream requestStream = request.GetRequestStream()) { requestStream.Write(fileContents, 0, fileContents.Length); } //Get the response from the FTP server FtpWebResponse response = (FtpWebResponse)request.GetResponse(); //Close the response and the request streams response.Close(); request.Abort(); 使用try catch

你问的是关于C#中使用FTP上传文件并使用try catch的问题对吗？如果是的话，可以在代码中使用try catch块来捕捉可能出现的异常，确保程序的稳定性和可靠性。例如：

try
{
//Create a WebRequest object
FtpWebRequest request = (FtpWebRequest)WebRequest.Create(ftpServerAddress + "/" + targetFolderPath + "/" + Path.GetFileName(sourceFilePath));
request.Method = WebRequestMethods.Ftp.UploadFile;
//Set username and password for the request
request.Credentials = new NetworkCredential(ftpUsername, ftpPassword);
//Read the file into a byte array
byte[] fileContents;
using (StreamReader sourceStream = new StreamReader(FullName))
{
fileContents = Encoding.UTF8.GetBytes(sourceStream.ReadToEnd());
}
//Set the content length of the file
request.ContentLength = fileContents.Length;
//Write the file to the request stream
using (Stream requestStream = request.GetRequestStream())
{
requestStream.Write(fileContents, 0, fileContents.Length);
}
//Get the response from the FTP server
FtpWebResponse response = (FtpWebResponse)request.GetResponse();
//Close the response and the request streams
response.Close();
request.Abort();
}
catch (Exception ex)
{
//Handle the exception
Console.WriteLine("An error occurred: " + ex.Message);
}
