HttpWebRequest::ContentType Property

Gets or sets the value of the Content-type HTTP header.

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

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

Property Value

Type: System::String
The value of the Content-type HTTP header. The default value is nullptr.

The ContentType property contains the media type of the request. Values assigned to the ContentType property replace any existing contents when the request sends the Content-type HTTP header.

To clear the Content-type HTTP header, set the ContentType property to nullptr.

NoteNote

The value for this property is stored in WebHeaderCollection . If WebHeaderCollection is set, the property value is lost.

The following code example sets the ContentType property.

// Set the 'Method' property of the 'Webrequest' to 'POST'.
myHttpWebRequest->Method = "POST";
Console::WriteLine( "\nPlease enter the data to be posted to the (http://www.contoso.com/codesnippets/next.asp) Uri :" );

// Create a new String* Object* to POST data to the Url.
String^ inputData = Console::ReadLine();

String^ postData = String::Concat( "firstone= ", inputData );
ASCIIEncoding^ encoding = gcnew ASCIIEncoding;
array<Byte>^ byte1 = encoding->GetBytes( postData );

// Set the content type of the data being posted.
myHttpWebRequest->ContentType = "application/x-www-form-urlencoded";

// Set the content length of the String* being posted.
myHttpWebRequest->ContentLength = byte1->Length;

Stream^ newStream = myHttpWebRequest->GetRequestStream();

newStream->Write( byte1, 0, byte1->Length );
Console::WriteLine( "The value of 'ContentLength' property after sending the data is {0}", myHttpWebRequest->ContentLength );

// Close the Stream Object*.
newStream->Close();
