[This documentation is for preview only, and is subject to change in later releases. Blank topics are included as placeholders.]

Gets or sets the Content-length HTTP header.

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

public override long ContentLength { get; set; }

Property Value

Type: System..::..Int64
The number of bytes of data to send to the Internet resource. The default is -1, which indicates the property has not been set and that there is no request data to send.

The ContentLength property contains the value to send as the Content-length HTTP header with the request.

Any value other than -1 in the ContentLength property indicates that the request uploads data and that only methods that upload data are allowed to be set in the Method property.

After the ContentLength property is set to a value, that number of bytes must be written to the request stream that is returned by calling the GetRequestStream method.
