Assembly: mscorlib (in mscorlib.dll)
Syntax
'Declaration

The literal value associated with the field. If the literal value is a class type with an element value of zero, the return value is nulla null reference (Nothing in Visual Basic).
Exceptions
| Exception | Condition |
|---|---|
| InvalidOperationException | The Constant table in unmanaged metadata does not contain a constant value for the current property. |
| FormatException | The type of the value is not one of the types permitted by the Common Language Specification (CLS). (See the ECMA Partition II specification.) |
| MethodAccessException | The member is invoked late-bound through mechanisms such as Type.InvokeMember. |
Remarks
This method is provided for designers of managed compilers and code analyzers.
This method can be used in both the execution context and the reflection-only context.
In unmanaged metadata, the Constant table is used to store constant values for fields, parameters, and properties. Constant information does not directly influence runtime behavior. Compilers inspect this information, at compile time, when importing metadata. If used, the value of a constant is embedded in the Microsoft intermediate language (MSIL) stream the compiler emits. There are no MSIL instructions that can be used to access the Constant table at run time.
