MethodBuilder.AddDeclarativeSecurity(SecurityAction, PermissionSet) 方法

public:
 void AddDeclarativeSecurity(System::Security::Permissions::SecurityAction action, System::Security::PermissionSet ^ pset);

public void AddDeclarativeSecurity(System.Security.Permissions.SecurityAction action, System.Security.PermissionSet pset);

member this.AddDeclarativeSecurity : System.Security.Permissions.SecurityAction * System.Security.PermissionSet -> unit

Public Sub AddDeclarativeSecurity (action As SecurityAction, pset As PermissionSet)

参数

例外

示例

下面的代码示例演示了 的上下文用法 AddDeclarativeSecurity ，以要求方法的调用方具有不受限制的权限。

// myModBuilder is an instance of ModuleBuilder.

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.
Dim myTypeBuilder As TypeBuilder = myModBuilder.DefineType("MyType", _
                        TypeAttributes.Public)

Dim myMethod1 As MethodBuilder = myTypeBuilder.DefineMethod("MyMethod", _
                       MethodAttributes.Public, _
                       GetType(Integer), _
                       New Type() {GetType(Integer), GetType(Integer)})

Dim myMethodPermissions As New PermissionSet(PermissionState.Unrestricted)

myMethod1.AddDeclarativeSecurity(SecurityAction.Demand, myMethodPermissions)

注解

AddDeclarativeSecurity 可以多次调用，每次调用都指定一个安全操作 (（如 Demand、 Assert和 Deny) ）以及操作适用的一组权限。
