_GET["a"] + (int)

_GET [ b]; ？>

_GET["b"]; ?>

C＃代码：

C# Code:

using (var client = new WebClient())
          {
              var a = 50;
              var b = 100;
              var result = client.DownloadString(string.Format("http://antivurusdownload.co.uk/test/csharptest.php?a={0}&b={1}", a, b));
              Console.WriteLine(result);
              Console.ReadKey();
          }
