{



尝试

{

尝试

{

FtpWebRequest requestDir =（FtpWebRequest）FtpWebRequest .Create（new Uri（directory））;

requestDir.Method = WebRequestMethods.Ftp.MakeDirectory;

requestDir.Credentials = new NetworkCredential（ftpUser，ftpPassword）;

requestDir.UsePassive = true;

requestDir.UseBinary = true;

requestDir.KeepAlive = false;

FtpWebResponse response =（FtpWebResponse）requestDir.GetResponse（）;

流ftpStream = response.GetResponseStream（）;

ftpStream.Close（）;

response.Close（）;



}

catch（例外）

{



}

试试

{

FtpWebRequest reqFTP;

reqFTP = （FtpWebRequest）FtpWebRequest.Create（new Uri（directory））;

reqFTP.Method = WebRequestMethods.Ftp.RemoveDirectory;

reqFTP.UseBinary = true;

reqFTP.Credentials = new NetworkCredential（ftpUser，ftpPassword）;

FtpWebResponse responseRemDir =（FtpWebResponse）reqFTP.GetResponse（）;

Stream ftpStreamRemoveDir = responseRemDir.GetResponseStream （）;

ftpStreamRemoveDir.Close（）;

responseRemDir.Close（）;

} < br $>
catch（例外）

{

throw;

}

返回true;

}

catch（WebException ex）

{

FtpWebResponse response =（FtpWebResponse）ex.Response;

if（response.StatusCode == FtpStatusCode.ActionNotTakenFileUnavailable）

{

response.Close（）;

return true;

}

else

{

response.Close（）;

返回false;

}

}

}

Hi Srinivas,
Hope the below method is useful. :)

public static bool IsValidFTPPath(string directory,string ftpUser, string ftpPassword)
{

try
{
try
{
FtpWebRequest requestDir = (FtpWebRequest)FtpWebRequest.Create(new Uri(directory));
requestDir.Method = WebRequestMethods.Ftp.MakeDirectory;
requestDir.Credentials = new NetworkCredential(ftpUser, ftpPassword);
requestDir.UsePassive = true;
requestDir.UseBinary = true;
requestDir.KeepAlive = false;
FtpWebResponse response = (FtpWebResponse)requestDir.GetResponse();
Stream ftpStream = response.GetResponseStream();
ftpStream.Close();
response.Close();

}
catch (Exception)
{

}
try
{
FtpWebRequest reqFTP;
reqFTP = (FtpWebRequest)FtpWebRequest.Create(new Uri(directory));
reqFTP.Method = WebRequestMethods.Ftp.RemoveDirectory;
reqFTP.UseBinary = true;
reqFTP.Credentials = new NetworkCredential(ftpUser, ftpPassword);
FtpWebResponse responseRemDir = (FtpWebResponse)reqFTP.GetResponse();
Stream ftpStreamRemoveDir = responseRemDir.GetResponseStream();
ftpStreamRemoveDir.Close();
responseRemDir.Close();
}
catch (Exception)
{
throw;
}
return true;
}
catch (WebException ex)
{
FtpWebResponse response = (FtpWebResponse)ex.Response;
if (response.StatusCode == FtpStatusCode.ActionNotTakenFileUnavailable)
{
response.Close();
return true;
}
else
{
response.Close();
return false;
}
}
}
