MemberInfo.MetadataToken Property (System.Reflection)

.NET Framework Class Library

MemberInfo..::.MetadataToken Property

Gets a value that identifies a metadata element.

Namespace: System.Reflection
Assembly: mscorlib (in mscorlib.dll)

Public Overridable ReadOnly Property MetadataToken As Integer
	Get

public virtual int MetadataToken { get; }

public:
virtual property int MetadataToken {
	int get ();
}

abstract MetadataToken : int
override MetadataToken : int

Property Value

Type: System..::.Int32
A value which, in combination with Module, uniquely identifies a metadata element.

Exceptions

Exception	Condition
InvalidOperationException	The current MemberInfo represents an array method, such as Address, on an array type whose element type is a dynamic type that has not been completed. To get a metadata token in this case, pass the MemberInfo object to the ModuleBuilder..::.GetMethodToken method; or use the ModuleBuilder..::.GetArrayMethodToken method to get the token directly, instead of using the ModuleBuilder..::.GetArrayMethod method to get a MethodInfo first.

Remarks

The tokens obtained using this property can be passed to the unmanaged reflection API. For more information, please see Unmanaged Reflection API.

Note
Using the unmanaged reflection API requires familiarity with the Common Language Infrastructure (CLI) documentation, especially "Partition II: Metadata Definition and Semantics" and "Partition III: CIL Instruction Set". The documentation is available online; see ECMA C# and Common Language Infrastructure Standards on MSDN and Standard ECMA-335 - Common Language Infrastructure (CLI) on the Ecma International Web site.
