Examples
The following code example shows how to use the EnableViewStateMac property.
// Get the current EnableViewStateMac property value.
Console.WriteLine(
"Current EnableViewStateMac value: '{0}'",
pagesSection.EnableViewStateMac);
// Set the EnableViewStateMac property to true.
pagesSection.EnableViewStateMac = true;
' Get the current EnableViewStateMac property value.
Console.WriteLine( _
"Current EnableViewStateMac value: '{0}'", _
pagesSection.EnableViewStateMac)
' Set the EnableViewStateMac property to true.
pagesSection.EnableViewStateMac = True
Remarks
A view-state MAC is an encrypted version of the hidden variable that a page's view state is persisted to when the page is sent to the browser. When this property is set to true, the encrypted view state is checked to verify that it has not been tampered with on the client.
Important
This attribute should never be set to false in a production Web site, even if the application or page does not use view state. The view state MAC helps ensure the security of other ASP.NET functions in addition to the view state.
