ArgumentException

No method is supplied.

-or-

The method string contains invalid characters.

NotImplementedException

This property is not implemented.

NotSupportedException

The Method property is not GET or POST.

Remarks

The Method property can only be set to GET and POST methods. Any other HTTP 1.1 or 1.0 protocol verbs (HEAD, PUT, DELETE, TRACE, or OPTIONS, for example) will throw a NotSupportedException exception.

If an application implements a custom WebRequest class and does not override the Method property, then the NotImplementedException is thrown.

Examples

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

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

' Set the 'Method' property to "POST".
myHttpWebRequest.Method="PUT"

' Set the 'ContentType' property.
myHttpWebRequest.ContentType="application/x-www-form-urlencoded"

' Get the 'ContentType' property and print the current value
outputBlock.Text &= "HttpWebRequest.ContentType: "
outputBlock.Text &= myHttpWebRequest.ContentType
outputBlock.Text &= vbCrLf

        // Change this Uri to a public server
        System.Uri myUri = new Uri("https://www.contoso.com");

        // Create a 'HttpWebRequest' object.
        HttpWebRequest myHttpWebRequest=(HttpWebRequest)WebRequest.Create(myUri);

        // Set the 'Method' property to "POST".
        myHttpWebRequest.Method="PUT";

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