Method |
yes |
The method that contains the parameter. |
|
Name |
Text |
The name of the parameter. |
|
Position |
Integer32 |
yes |
The zero-based index of the position of the parameter within the method declaration. |
Type |
yes |
The type signature of the parameter. |
|
DefaultValue |

The default value for the parameter. |
|
IsByReference |
Logical |
yes |
A bit flag that specifies that the parameter is passed by reference. |
IsInParameter |

|
MarshaledArraySizeParameterIndex |
Integer32 |
The index to the parameter in the method that provides the number of elements in a marshaled ECMA-335 native array (LPArray). |
|
MarshaledArraySizeConst |
Integer32 |
The size of a marshaled array specified as a literal value. This value applies only to marshaled array parameters with a predetermined size. |
