TypeLibFuncAttribute 类

定义

包含最初从 COM 类型库为此方法导入的 FUNCFLAGSContains the FUNCFLAGS that were originally imported for this method from the COM type library.

public sealed class TypeLibFuncAttribute : Attribute
[System.AttributeUsage(System.AttributeTargets.Method, Inherited=false)]
[System.Runtime.InteropServices.ComVisible(true)]
public sealed class TypeLibFuncAttribute : Attribute
type TypeLibFuncAttribute = class
    inherit Attribute
Public NotInheritable Class TypeLibFuncAttribute

示例

下面的示例演示如何获取方法的 TypeLibFuncAttribute 值。The following example demonstrates how to get the TypeLibFuncAttribute value of a method.

using namespace System;
using namespace System::Reflection;
using namespace System::Runtime::InteropServices;

ref class ClassC
{
private:
   static bool IsHiddenMethod( MethodInfo^ mi )
   {
      array<Object^>^MethodAttributes = mi->GetCustomAttributes( TypeLibFuncAttribute::typeid, true );
      if ( MethodAttributes->Length > 0 )
      {
         TypeLibFuncAttribute^ tlf = dynamic_cast<TypeLibFuncAttribute^>(MethodAttributes[ 0 ]);
         TypeLibFuncFlags flags = tlf->Value;
         return (flags & TypeLibFuncFlags::FHidden) != (TypeLibFuncFlags)0;
      }

      return false;
   }
};

using System;
using System.Reflection;
using System.Runtime.InteropServices;

namespace C
{
    class ClassC	
    {
        public static bool IsHiddenMethod( MethodInfo mi )
        {
            object[] MethodAttributes = mi.GetCustomAttributes( typeof( TypeLibFuncAttribute ), true);
        
            if( MethodAttributes.Length > 0 )
            {
                TypeLibFuncAttribute tlf = ( TypeLibFuncAttribute )MethodAttributes[0];
                TypeLibFuncFlags  flags = tlf.Value;
                return ( flags & TypeLibFuncFlags.FHidden ) != 0;
            }
            return false;
        }
    }
}
Imports System.Reflection
Imports System.Runtime.InteropServices

Module C
    Public Function IsHiddenMethod(ByVal mi As MethodInfo) As Boolean
        Dim MethodAttributes As Object() = mi.GetCustomAttributes(GetType(TypeLibFuncAttribute), True)

        If MethodAttributes.Length > 0 Then
            Dim tlf As TypeLibFuncAttribute = MethodAttributes(0)
            Dim flags As TypeLibFuncFlags = tlf.Value
            Return (flags & TypeLibFuncFlags.FHidden) > 0
        End If
        Return False
    End Function
End Module

注解

Tlbimp.exe (类型库导入程序)将此特性应用于方法。The Tlbimp.exe (Type Library Importer) applies this attribute to methods.

当导入类型库时,将应用此特性,并且永远不应更改。This attribute is applied when a type library is imported and should never be changed. 仅当该方法的 FUNCFLAGS 的计算结果为非零时,才会应用该方法。It is only applied when the method's FUNCFLAGS evaluate to non zero. 特性旨在供需要了解原始 FUNCFLAGS 设置方式的工具使用。The attribute is designed to be used by tools that need to know how the original FUNCFLAGS were set. 公共语言运行时不使用此属性。The common language runtime does not use this attribute.

构造函数

TypeLibFuncAttribute(Int16)

使用指定的 TypeLibFuncFlags 值初始化 TypeLibFuncAttribute 类的新实例。Initializes a new instance of the TypeLibFuncAttribute class with the specified TypeLibFuncFlags value.

TypeLibFuncAttribute(TypeLibFuncFlags)

使用指定的 TypeLibFuncFlags 值初始化 TypeLibFuncAttribute 类的新实例。Initializes a new instance of the TypeLibFuncAttribute class with the specified TypeLibFuncFlags value.

属性
