WebRequest.ContentType Property (System.Net)

ContentType Property

.NET Framework Class Library

WebRequest..::.ContentType Property

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

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

Syntax

Visual Basic (Declaration)

Public Overridable Property ContentType As String

Visual Basic (Usage)

Dim instance As WebRequest
Dim value As String

value = instance.ContentType

instance.ContentType = value

public virtual string ContentType { get; set; }

Visual C++

public:
virtual property String^ ContentType {
    String^ get ();
    void set (String^ value);
}

JScript

public function get ContentType () : String
public function set ContentType (value : String)

Property Value

Type: System..::.String
The content type of the request data.

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 ContentType property contains the media type of the request. This is typically the MIME encoding of the content.

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 ContentType property to the appropriate media type.

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();

CPP_OLD

// Set the 'ContentType' property of the WebRequest.
myWebRequest->ContentType=S"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();
