public void AddDeclarativeSecurity (
	SecurityAction action,
	PermissionSet pset
)
public void AddDeclarativeSecurity (
	SecurityAction action, 
	PermissionSet pset
)
public function AddDeclarativeSecurity (
	action : SecurityAction, 
	pset : PermissionSet
)

Parameters

action

The security action to be taken (Demand, Assert, and so on).

pset

The set of permissions the action applies to.

Exception typeCondition

ArgumentOutOfRangeException

The action is invalid (RequestMinimum, RequestOptional, and RequestRefuse are invalid).

InvalidOperationException

The containing type has been created using CreateType.

-or-

The permission set pset contains an action that was added earlier by AddDeclarativeSecurity.

-or-

For the current method, the IsGenericMethod property is true, but the IsGenericMethodDefinition property is false.

ArgumentNullException

pset is a null reference (Nothing in Visual Basic).

The code sample below illustrates the contextual use of AddDeclarativeSecurity to require the caller of a method to have unrestricted permissions.

// myModBuilder is an instance of ModuleBuilder.
// Note that for the use of PermissionSet and SecurityAction,
// the namespaces System.Security and System.Security.Permissions
// should be included.

TypeBuilder myTypeBuilder = myModBuilder.DefineType("MyType",
                    TypeAttributes.Public);

                    
MethodBuilder myMethod1 = myTypeBuilder.DefineMethod("MyMethod",
                    MethodAttributes.Public, 
                    typeof(int),
                    new Type[] 
                    {typeof(int), typeof(int)});    

PermissionSet myMethodPermissions = new PermissionSet(
            PermissionState.Unrestricted);

myMethod1.AddDeclarativeSecurity(SecurityAction.Demand,
                 myMethodPermissions);


// myModBuilder is an instance of ModuleBuilder.
// Note that for the use of PermissionSet and SecurityAction,
// the namespaces System.Security and System.Security.Permissions
// should be included.
TypeBuilder myTypeBuilder = myModBuilder.DefineType("MyType",
    TypeAttributes.Public);
MethodBuilder myMethod1 = myTypeBuilder.DefineMethod("MyMethod",
    MethodAttributes.Public,int.class.ToType(),
    new Type[] { int.class.ToType(), int.class.ToType() });
PermissionSet myMethodPermissions =
    new PermissionSet(PermissionState.Unrestricted);
myMethod1.AddDeclarativeSecurity(SecurityAction.Demand,
    myMethodPermissions);
