Property Value

Type: System.Object
The default value of the parameter, or Value if the parameter has no default value.

Remarks

The default value is used when an actual value is not specified in the method call. A parameter can have a default value that is nulla null reference (Nothing in Visual Basic). This is distinct from the case where a default value is not defined.

To get the ParameterInfo array, first get the method or the constructor, and then call MethodBase.GetParameters.
