title: The SaveAs method is configured to require a rooted path, and the path 'fp' is not rooted
body: <p>I am doing Image uploader in Asp.net and I am  giving following code under my controls:</p>
  
  <pre><code>    string st;
      st = tt.PostedFile.FileName;
      Int32 a;
      a = st.LastIndexOf("\\");
      string fn;
      fn = st.Substring(a + 1);
      string fp;
      fp = Server.MapPath(" ");
      fp = fp + "\\";
      fp = fp + fn;
      tt.PostedFile.SaveAs("fp");
  </code></pre>
  
  <p>But during uploading or saving image the error message comes that The <strong>SaveAs method is configured to require a rooted path, and the path 'fp' is not rooted.</strong> 
  So Please help me what is the problem</p>
