Module.ResolveField Method (Int32, array<Type[], array<Type[])

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Returns the field identified by the specified metadata token, in the context defined by the specified generic type parameters.

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

Syntax

'Declaration
Public Overridable Function ResolveField ( _
    metadataToken As Integer, _
    genericTypeArguments As Type(), _
    genericMethodArguments As Type() _
) As FieldInfo

public virtual FieldInfo ResolveField(
    int metadataToken,
    Type[] genericTypeArguments,
    Type[] genericMethodArguments
)

Parameters

metadataToken
Type: System.Int32
A metadata token that identifies a field in the module.

genericTypeArguments
Type: array<System.Type[]
An array of Type objects representing the generic type arguments of the type where the token is in scope, or nulla null reference (Nothing in Visual Basic) if that type is not generic.

genericMethodArguments
Type: array<System.Type[]
An array of Type objects representing the generic type arguments of the method where the token is in scope, or nulla null reference (Nothing in Visual Basic) if that method is not generic.

Return Value

Type: System.Reflection.FieldInfo
A FieldInfo object representing the field that is identified by the specified metadata token.

Exceptions

Exception	Condition
ArgumentException	metadataToken is not a token for a field in the scope of the current module. -or- metadataToken identifies a field whose parent TypeSpec has a signature containing element type var (a type parameter of a generic type) or mvar (a type parameter of a generic method), and the necessary generic type arguments were not supplied for either or both of genericTypeArguments and genericMethodArguments.
ArgumentOutOfRangeException	metadataToken is not a valid token in the scope of the current module.

ArgumentException

metadataToken is not a token for a field in the scope of the current module.

-or-

metadataToken identifies a field whose parent TypeSpec has a signature containing element type var (a type parameter of a generic type) or mvar (a type parameter of a generic method), and the necessary generic type arguments were not supplied for either or both of genericTypeArguments and genericMethodArguments.

ArgumentOutOfRangeException

metadataToken is not a valid token in the scope of the current module.

Remarks

Use the Type.GetGenericArguments method on the type where metadataToken is in scope to obtain an array of generic type arguments for genericTypeArguments. Use the MethodInfo.GetGenericArguments method on the method where metadataToken is in scope to obtain an array of generic type arguments for genericTypeArguments. It is always safe to provide these arguments, even when they are not needed.

Note:
Information about metadata tokens can be found in the Common Language Infrastructure (CLI) documentation, especially "Partition II: Metadata Definition and Semantics". 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 Web site.

For code that demonstrates token resolution using the generic context (that is, the generic type parameters of the generic type and/or the generic method in which the token is embedded) see the ResolveMethod(Int32, array<Type[], array<Type[]) method.
