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

Public Overrides Property ContentType As String

Property Value

Type: System.String
The value of the Content-type HTTP header. The default value is Nothing.

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 Nothing.


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

' Change this Uri to a public server
Dim myUri As System.Uri = New Uri("http://www.contoso.com")

' Create a 'HttpWebRequest' object.
Dim myHttpWebRequest As HttpWebRequest = WebRequest.Create(myUri)

' Set the 'Method' property to "POST".

' Set the 'ContentType' property.

' Get the 'ContentType' property and print the current value

outputBlock.Text &= myHttpWebRequest.ContentType
outputBlock.Text &= vbCrLf
