C# check URL exist ?

microstar

How can I check an address URL exists or not ?
I have this code :

private void check(string path)
        {

            try
            {
                Uri uri = new Uri(path);
                WebRequest request = WebRequest.Create(uri);
                request.Timeout = 3000;
                WebResponse response;
                response = request.GetResponse();

            }
            catch(Exception loi) { MessageBox.Show(loi.Message); }

        }

but that error message about the proxy :(

Accepted answer

You can Check URL by Following Code ..

bool Test  = true;
Uri urlCheck = new Uri(url);
WebRequest request = WebRequest.Create(urlCheck);
request.Timeout = 15000;

WebResponse response;
try
{
     response = request.GetResponse();
}
catch (Exception)
{
     Test false; //url does not exist
}

if(Test== false)


{
       //url does not exist 
}

Well you are getting beyond my area of experience. I think you need to modify your Configuration File but I am not sure about that.

Does it help to add:
request.Credentials = CredentialCache.DefaultCredentials;
