DataProtectionPermissionAttribute Class

Note: This class is new in the .NET Framework version 2.0.

Allows security actions for DataProtectionPermission to be applied to code using declarative security. This class cannot be inherited.

Namespace: System.Security.Permissions
Assembly: System.Security (in system.security.dll)

[SerializableAttribute] 
[AttributeUsageAttribute(AttributeTargets.Assembly|AttributeTargets.Class|AttributeTargets.Struct|AttributeTargets.Constructor|AttributeTargets.Method, AllowMultiple=true, Inherited=false)] 
public sealed class DataProtectionPermissionAttribute : CodeAccessSecurityAttribute
/** @attribute SerializableAttribute() */ 
/** @attribute AttributeUsageAttribute(AttributeTargets.Assembly|AttributeTargets.Class|AttributeTargets.Struct|AttributeTargets.Constructor|AttributeTargets.Method, AllowMultiple=true, Inherited=false) */ 
public final class DataProtectionPermissionAttribute extends CodeAccessSecurityAttribute
SerializableAttribute 
AttributeUsageAttribute(AttributeTargets.Assembly|AttributeTargets.Class|AttributeTargets.Struct|AttributeTargets.Constructor|AttributeTargets.Method, AllowMultiple=true, Inherited=false) 
public final class DataProtectionPermissionAttribute extends CodeAccessSecurityAttribute

The scope of the declaration that is allowed depends on the SecurityAction value that is used.

The security information declared by a security attribute is stored in the metadata of the attribute target and is accessed by the system at run time. DataProtectionPermissionAttribute is used only for declarative security. For imperative security, use the DataProtectionPermission class.

The following code example shows the use of the DataProtectionPermissionAttribute. This code example is part of a larger example provided for the DataProtectionPermission class.

[DataProtectionPermission(
     SecurityAction.Deny, 
     Flags = DataProtectionPermissionFlags.ProtectData)]
private static void TryProtectData()
{
    try
    {
        ProtectData();
        return;
    }
    catch (SecurityException e)
    {
        Console.WriteLine("A security exception thrown when attempting:" +
            ((DataProtectionPermission)e.DenySetInstance).Flags);
        return;
    }
}


/** @attribute DataProtectionPermission(SecurityAction.Deny, 
    Flags = DataProtectionPermissionFlags.ProtectData)
 */
private static void TryProtectData()
{
    try {
        ProtectData();
        return;
    }
    catch (System.Security.SecurityException e) {
        Console.WriteLine("A security exception thrown when attempting:" 
            + ((DataProtectionPermission)(e.get_DenySetInstance())).
            get_Flags());
        return;
    }
} //TryProtectData
