MetadataToken Property

MemberInfo.MetadataToken Property


Gets a value that identifies a metadata element.

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

public virtual int MetadataToken { get; }

Property Value

Type: System.Int32

A value which, in combination with Module, uniquely identifies a metadata element.

Exception Condition

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.

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


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.
