How should I try 3 times if my code failed to connect a web service in C#?

Question

Here is my code:

FtpWebRequest reqFTP;
reqFTP = (FtpWebRequest)FtpWebRequest.Create(Constant.IP);
reqFTP.Credentials = new NetworkCredential(UserName, Password);
reqFTP.Method = WebRequestMethods.Ftp.ListDirectory;
response = (FtpWebResponse)reqFTP.GetResponse();
Stream responseStream = response.GetResponseStream();
reader = new StreamReader(responseStream);

I would like to try to connect to the web service if my code fails to connect. Only after 3 times, I would like to give up.

How should I try?

I am thinking about try catch and count the failure time but I think there will be better solutions.

Answer 1

Encapsulate your code in loop, and return or break if there is no exception.

Answer 2

int faultCounter = 0;
bool faulted;
do {
  faulted = false;
  try {
    // perform service operation
  } catch {
    faultCounter++;
    faulted = true;
  }
} while (faulted && faultCounter < 3);
