[Visual Basic] Public Shared Function GetTypeFromHandle( _ ByVal handle As RuntimeTypeHandle _ ) As Type [C#] public static Type GetTypeFromHandle( RuntimeTypeHandle handle ); [C++] public: static Type* GetTypeFromHandle( RuntimeTypeHandle handle ); [JScript] public static function GetTypeFromHandle( handle : RuntimeTypeHandle ) : Type;
Parameters
- handle
- The RuntimeTypeHandle object that refers to the type.
Return Value
The type referenced by the specified RuntimeTypeHandle.
Exceptions
| Exception Type | Condition |
|---|---|
| ArgumentNullException | handle is a null reference (Nothing in Visual Basic). |
| TargetInvocationException | A class initializer is invoked and throws an exception. |
Remarks
The handles are valid only in the application domain in which they were obtained.
If the requested type is non-public and the caller does not have ReflectionPermission to reflect non-public objects outside the current assembly, this method returns a null reference (Nothing in Visual Basic).
Example
[Visual Basic] Dim myClass1 As New MyClass1() ' Get the type referenced by the specified type handle. Dim myClass1Type As Type = Type.GetTypeFromHandle(Type.GetTypeHandle(MyClass1)) Console.WriteLine(("The Names of the Attributes :" + myClass1Type.Attributes.ToString())) End Sub 'Main [C#] MyClass1 myClass1 = new MyClass1(); // Get the type referenced by the specified type handle. Type myClass1Type = Type.GetTypeFromHandle(Type.GetTypeHandle(myClass1)); Console.WriteLine("The Names of the Attributes :"+myClass1Type.Attributes); [C++] MyClass1* myClass1 = new MyClass1(); // Get the type referenced by the specified type handle. Type* myClass1Type = Type::GetTypeFromHandle(Type::GetTypeHandle(myClass1)); Console::WriteLine(S"The Names of the Attributes : {0}",__box( myClass1Type->Attributes));
