Remarks
The type modifiers form the basis for representing more complex types. A CorElementType type modifier value is applied to the value that immediately follows it in the type signature. The value that follows the CorElementType type modifier value can be a CorElementType simple type value, a metadata token, or other value as specified in the table below.
| Type Modifier | Format |
|---|---|
ELEMENT_TYPE_PTR |
ELEMENT_TYPE_PTR <a CorElementType value> |
ELEMENT_TYPE_BYREF |
ELEMENT_TYPE_BYREF <a CorElementType value> |
ELEMENT_TYPE_VALUETYPE |
ELEMENT_TYPE_VALUETYPE <an mdTypeDef metadata token> |
ELEMENT_TYPE_CLASS |
ELEMENT_TYPE_CLASS <an mdTypeDef metadata token> |
ELEMENT_TYPE_VAR |
ELEMENT_TYPE_VAR <ELEMENT_TYPE_U1> |
ELEMENT_TYPE_ARRAY |
ELEMENT_TYPE_ARRAY <a CorElementType value> <rank> <count1> <bound1> ... <countN> <boundN> |
