RuntimeTypeHandle 结构

表示使用内部元数据标记的类型。

**命名空间:**System
**程序集:**mscorlib（在 mscorlib.dll 中）

语法

声明
<SerializableAttribute> _
<ComVisibleAttribute(True)> _
Public Structure RuntimeTypeHandle
    Implements ISerializable
用法
Dim instance As RuntimeTypeHandle

[SerializableAttribute] 
[ComVisibleAttribute(true)] 
public struct RuntimeTypeHandle : ISerializable

[SerializableAttribute] 
[ComVisibleAttribute(true)] 
public value class RuntimeTypeHandle : ISerializable

/** @attribute SerializableAttribute() */ 
/** @attribute ComVisibleAttribute(true) */ 
public final class RuntimeTypeHandle extends ValueType implements ISerializable

JScript 支持使用结构，但不支持进行新的声明。

示例

下面的示例说明如何获取 RuntimeTypeHandle。

Imports System
Imports System.Reflection

 _
Public Class MyClass1
   Private x As Integer = 0
   
   Public Function MyMethod() As Integer
      Return x
   End Function 'MyMethod
End Class 'MyClass1
 _
Public Class MyClass2
   
   Public Shared Sub Main()
      Dim myClass1 As New MyClass1()
      
      ' Get the RuntimeTypeHandle from an object.
      Dim myRTHFromObject As RuntimeTypeHandle = Type.GetTypeHandle(myClass1)
      ' Get the RuntimeTypeHandle from a type.
      Dim myRTHFromType As RuntimeTypeHandle = GetType(MyClass1).TypeHandle
      
      Console.WriteLine("myRTHFromObject.Value: {0}", myRTHFromObject.Value)
      Console.WriteLine("myRTHFromObject.Type: {0}", myRTHFromObject.GetType())
      Console.WriteLine("myRTHFromType.Value: {0}", myRTHFromType.Value)
      Console.WriteLine("myRTHFromType.Type: {0}", myRTHFromType.GetType())
   End Sub 'Main 
End Class 'MyClass2

        Console.WriteLine("myRTHFromType.Type: {0}", myRTHFromType.GetType());

    }

        RuntimeTypeHandle myRTHFromObject = Type.GetTypeHandle(myClass1);

        RuntimeTypeHandle myRTHFromType = (MyClass1.class.ToType()).
            get_TypeHandle();

        Console.WriteLine("myRTHFromObject.Value: {0}", myRTHFromObject.

线程安全

此类型的任何公共静态（Visual Basic 中的 Shared）成员都是线程安全的，但不保证所有实例成员都是线程安全的。
