Microsoft Silverlight will reach end of support after October 2021. Learn more.

When overridden in a descendant class, gets or sets the content length of data being received.

Namespace:  System.Net
Assembly:  System.Net (in System.Net.dll)

'Declaration
Public MustOverride ReadOnly Property ContentLength As Long
public abstract long ContentLength { get; }

Property Value

Type: System.Int64
The number of bytes returned from the Internet resource.

Exceptions

Exception Condition
NotSupportedException

Any attempt is made to get or set the property, when the property is not overridden in a descendant class.

Remarks

The ContentLength property contains the length, in bytes, of the response from the Internet resource. For request methods that contain header information, the ContentLength does not include the length of the header information.

NoteNote:

The WebResponse class is an abstract class. The actual behavior of WebResponse instances at run time is determined by the descendant class returned by WebRequest.EndGetResponse. For more information about default values and exceptions, please see the documentation for the descendant classes, such as HttpWebResponse.
