public virtual long ContentLength { get; set; }

member this.ContentLength : int64 with get, set

Public Overridable Property ContentLength As Long

Property Value

Int64

The number of bytes of request data being sent.

Exceptions

NotImplementedException

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

Examples

The following example sets the ContentLength property to the amount of bytes in the outgoing byte buffer.

// Set the 'ContentType' property of the WebRequest.
myWebRequest->ContentType = "application/x-www-form-urlencoded";

// Set the 'ContentLength' property of the WebRequest.
myWebRequest->ContentLength = byteArray->Length;
Stream^ newStream = myWebRequest->GetRequestStream();
newStream->Write( byteArray, 0, byteArray->Length );

// Close the Stream object.
newStream->Close();

// Assign the response object of 'WebRequest' to a 'WebResponse' variable.
WebResponse^ myWebResponse = myWebRequest->GetResponse();

// Set the 'ContentType' property of the WebRequest.
myWebRequest.ContentType="application/x-www-form-urlencoded";

// Set the 'ContentLength' property of the WebRequest.
myWebRequest.ContentLength=byteArray.Length;
Stream newStream=myWebRequest.GetRequestStream();
newStream.Write(byteArray,0,byteArray.Length);

// Close the Stream object.
newStream.Close();

// Assign the response object of 'WebRequest' to a 'WebResponse' variable.
WebResponse myWebResponse=myWebRequest.GetResponse();

' Set the 'ContentType' property of the WebRequest.
myWebRequest.ContentType = "application/x-www-form-urlencoded"

' Set the 'ContentLength' property of the WebRequest.
myWebRequest.ContentLength = byteArray.Length
Dim newStream As Stream = myWebRequest.GetRequestStream()
newStream.Write(byteArray, 0, byteArray.Length)

' Close the Stream object.
newStream.Close()

' Assign the response object of 'WebRequest' to a 'WebResponse' variable.
Dim myWebResponse As WebResponse = myWebRequest.GetResponse()

Remarks

Caution

WebRequest, HttpWebRequest, ServicePoint, and WebClient are obsolete, and you shouldn't use them for new development. Use HttpClient instead.

The ContentLength property contains the number of bytes of data sent to the Internet resource by the WebRequest instance.

Note

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