Module.ResolveField Method

  • Reference

Definition

Namespace:
System.Reflection
Assembly:
System.Runtime.dll
Assembly:
mscorlib.dll
Assembly:
netstandard.dll

Returns the field identified by a metadata token.

Overloads

ResolveField(Int32)

Returns the field identified by the specified metadata token.
ResolveField(Int32, Type[], Type[])

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

Returns the field identified by the specified metadata token.

public:
 System::Reflection::FieldInfo ^ ResolveField(int metadataToken);
public System.Reflection.FieldInfo? ResolveField (int metadataToken);
public System.Reflection.FieldInfo ResolveField (int metadataToken);
member this.ResolveField : int -> System.Reflection.FieldInfo
Public Function ResolveField (metadataToken As Integer) As FieldInfo

Parameters

metadataToken
Int32

A metadata token that identifies a field in the module.

Returns

FieldInfo

A FieldInfo object representing the field that is identified by the specified metadata token.

Exceptions

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).

ArgumentOutOfRangeException

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

Remarks

To resolve a metadata token that identifies a field whose parent TypeSpec has a signature containing element type ELEMENT_TYPE_VAR or ELEMENT_TYPE_MVAR, use the ResolveField(Int32, Type[], Type[]) method overload, which allows you to supply the necessary context. That is, when you are resolving a metadata token for a field that depends on the generic type parameters of the generic type and/or the generic method in which the token is embedded, you must use the overload that allows you to supply those type parameters.

Note

Information about metadata tokens can be found in the Common Language Infrastructure (CLI) documentation, especially "Partition II: Metadata Definition and Semantics". For more information, see ECMA 335 Common Language Infrastructure (CLI).

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, Type[], Type[]) method.

 virtual System::Reflection::FieldInfo ^ ResolveField(int metadataToken, cli::array <Type ^> ^ genericTypeArguments, cli::array <Type ^> ^ genericMethodArguments);

abstract member ResolveField : int * Type[] * Type[] -> System.Reflection.FieldInfo

member this.ResolveField : int * Type[] * Type[] -> System.Reflection.FieldInfo
Public Overridable Function ResolveField (metadataToken As Integer, genericTypeArguments As Type(), genericMethodArguments As Type()) As FieldInfo
Public Function ResolveField (metadataToken As Integer, genericTypeArguments As Type(), genericMethodArguments As Type()) As FieldInfo

Parameters

metadataToken
Int32

A metadata token that identifies a field in the module.

genericTypeArguments
Type[]

An array of Type objects representing the generic type arguments of the type where the token is in scope, or null if that type is not generic.

genericMethodArguments
Type[]

An array of Type objects representing the generic type arguments of the method where the token is in scope, or null if that method is not generic.

Returns

FieldInfo

A FieldInfo object representing the field that is identified by the specified metadata token.

Exceptions

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". For more information, see ECMA 335 Common Language Infrastructure (CLI).

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, Type[], Type[]) method.
