SecurityRoleAttribute Class

Definition

Configures a role for an application or component. This class cannot be inherited.

public ref class SecurityRoleAttribute sealed : Attribute
[System.Runtime.InteropServices.ComVisible(false)]
[System.AttributeUsage(System.AttributeTargets.Assembly | System.AttributeTargets.Class | System.AttributeTargets.Interface | System.AttributeTargets.Method, AllowMultiple=true, Inherited=true)]
public sealed class SecurityRoleAttribute : Attribute
type SecurityRoleAttribute = class

Attributes

Examples

The following code example demonstrates the use of this attribute to associate a role with an assembly that contains ServicedComponent classes.

// Create a security role for the component.
[assembly:SecurityRole("Manager")];
// Create a security role for the component.
[assembly: SecurityRole("Manager")]
' Create a security role for the component.
<Assembly: SecurityRole("Manager")> 

Remarks

You can use the SecurityRoleAttribute to add roles to an application, and to associate them with components. When SecurityRoleAttribute is applied to an assembly as a whole, it ensures that the role exists in the application configuration (COM+ catalog). You can add members of the role using the COM+ Explorer.

When applied to a component, the SecurityRoleAttribute ensures that the role exists in the application configuration, and associates the target component with the role.

By default, created roles have no members. If the SetEveryoneAccess property is set to true, the Everyone user group is automatically added to the role. This is best for all-access type roles that are given minimal control over the system.

Security roles can be specified at the component level, per interface and per method. As with other method attributes, security configuration is not currently shared between interface definition and method implementation.

Constructors

SecurityRoleAttribute(String)

Initializes a new instance of the SecurityRoleAttribute class and sets the Role property.

SecurityRoleAttribute(String, Boolean)

Initializes a new instance of the SecurityRoleAttribute class and sets the Role and SetEveryoneAccess properties.

Explicit Interface Implementations

_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)

Maps a set of names to a corresponding set of dispatch identifiers.
