CookieParameter.CookieParameter() Constructor

Initializes a new unnamed instance of the CookieParameter class.

Namespace: System.Web.UI.WebControls
Assembly: System.Web (in system.web.dll)

public:
CookieParameter ()
public CookieParameter ()
public function CookieParameter ()
Not applicable.

A CookieParameter object created with the CookieParameter constructor is initialized with default values for all its properties. The CookieName property is initialized to String.Empty. Additionally, the Name property is initialized to String.Empty, the Type property is initialized to TypeCode.Object, the Direction property is initialized to Input, and the DefaultValue property is initialized to a null reference (Nothing in Visual Basic).

The following code example demonstrates how to create a CookieParameter object using the CookieParameter constructor, set its Name, Type, and CookieName properties, and then add it to a SqlDataSource control's SelectParameters collection.

No code example is currently available or this language may not be supported.
