The ContentLength property contains the length, in bytes, of the file system resource.

The following example uses the ContentLength property to obtain the content length of the file system resource.

public static void GetPage(String url) 
 {
   try 
     {     
         Uri fileUrl = new Uri("file://"+url);
         // Create a 'FileWebrequest' object with the specified Uri.
         FileWebRequest myFileWebRequest = (FileWebRequest)WebRequest.Create(fileUrl); 
         // Send the 'fileWebRequest' and wait for response.    
         FileWebResponse myFileWebResponse = (FileWebResponse)myFileWebRequest.GetResponse(); 
         // Print the ContentLength and ContentType properties received as headers in the response object.
         Console.WriteLine("\nContent length :{0}, Content Type : {1}",myFileWebResponse.ContentLength,myFileWebResponse.ContentType);  
         // Release resources of response object.
         myFileWebResponse.Close();
     } 
   catch(WebException e) 
     {
         Console.WriteLine("\r\nWebException thrown.The Reason for failure is : {0}",e.Status); 
     }
   catch(Exception e)
     {
         Console.WriteLine("\nThe following Exception was raised : {0}",e.Message);
     }
}

public static void GetPage(String url)
{
    try {
        Uri fileUrl = new Uri("file://" + url);

        // Create a 'FileWebrequest' object with the specified Uri.
        FileWebRequest myFileWebRequest = (FileWebRequest)(WebRequest.
            Create(fileUrl));

        // Send the 'fileWebRequest' and wait for response.    
        FileWebResponse myFileWebResponse = (FileWebResponse)(
            myFileWebRequest.GetResponse());

        // Print the ContentLength and ContentType properties received as
        // headers in the response object.
        Console.WriteLine("\nContent length :{0}, Content Type : {1}",
            System.Convert.ToString(myFileWebResponse.get_ContentLength()),
            myFileWebResponse.get_ContentType());

        // Release resources of response object.
        myFileWebResponse.Close();
    }
    catch (WebException e) {
        Console.WriteLine("\r\nWebException thrown.The Reason for failure "
            + " is : {0}", e.get_Status());
    }
    catch (System.Exception e) {
        Console.WriteLine("\nThe following Exception was raised : {0}",
            e.get_Message());
    }
} //GetPage
