SecurityPolicySection Class

Definition

Defines configuration settings that are used to support the security infrastructure of a Web application. This class cannot be inherited.

public ref class SecurityPolicySection sealed : System::Configuration::ConfigurationSection
public sealed class SecurityPolicySection : System.Configuration.ConfigurationSection
type SecurityPolicySection = class
    inherit ConfigurationSection
Public NotInheritable Class SecurityPolicySection
Inherits ConfigurationSection
Inheritance

Examples

This example demonstrates how to specify values declaratively within the securityPolicy section, which can also be accessed as members of the SecurityPolicySection class.

The following configuration file example shows how to specify values declaratively for the securityPolicy section.

<system.web>  
  <securityPolicy>  
    <trustLevel name="Full" policyFile="internal" />  
    <trustLevel name="High" policyFile="web_hightrust.config" />  
    <trustLevel name="Medium" policyFile="web_mediumtrust.config" />  
    <trustLevel name="Low" policyFile="web_lowtrust.config" />  
    <trustLevel name="Minimal" policyFile="web_minimaltrust.config" />  
  </securityPolicy>  
</system.web>  

The following code example demonstrates how to use the SecurityPolicySection class.
