TrustSection TrustSection TrustSection TrustSection Class

Definition

Configures the code-access security level that is applied to an application. This class cannot be inherited.

public ref class TrustSection sealed : System::Configuration::ConfigurationSection
public sealed class TrustSection : System.Configuration.ConfigurationSection
type TrustSection = class
    inherit ConfigurationSection
Public NotInheritable Class TrustSection

Examples

This section provides two code examples. The first demonstrates how to declaratively specify values for several properties of the TrustSection class. The second demonstrates how to use the TrustSection type.

The following configuration file example shows how to declaratively specify values for several properties of the TrustSection class.

<system.web>  
  <trust level="Full" originUrl=""/>  
</system.web>  

The following code example demonstrates how to use the TrustSection type.

Remarks

The TrustSection class lets you programmatically access and modify the configuration file <trust> section. The <trust> section configures the code-access-security permissions set that is used to run a particular application. This section can be declared at the machine, site, and application levels.

Constructors

TrustSection() TrustSection() TrustSection() TrustSection()

Initializes a new instance of the TrustSection class using default settings.
