Microsoft Developer Network

ContentLength Property

.NET Framework Class Library

WebRequest..::.ContentLength Property

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

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

Syntax

Visual Basic (Declaration)

Public Overridable Property ContentLength As Long

Visual Basic (Usage)

Dim instance As WebRequest
Dim value As Long

value = instance.ContentLength

instance.ContentLength = value

public virtual long ContentLength { get; set; }

Visual C++

public:
virtual property long long ContentLength {
    long long get ();
    void set (long long value);
}

JScript

public function get ContentLength () : long
public function set ContentLength (value : long)

Property Value

Type: System..::.Int64
The number of bytes of request data being sent.

Exceptions

Exception	Condition
NotImplementedException	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 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.

Examples

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

Visual Basic


' 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()

            // 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();

Visual C++

// 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();
