Note
If a matching indexed property could be found and the invocation itself has thrown an exception, then this method also throws an exception instead of returning .

static member TryGetIndexedMember :
instance : Object *
way : ReflectionWays *
value : Object byref *
indexParameters : Object[] -> bool Parameters
- instance Object
- An instance to be set.
- way ReflectionWays
- The preferred reflection way. TypeDescriptor way is not applicable here. This parameter is ignored for arrays.
- value Object
- When this method returns with result, then this parameter contains the value returned by the indexable object.
- indexParameters Object
- The index parameters.
Return Value
Boolean, if the indexed member could be read; , if a matching property or array getter could not be found.
Remarks
This method ignores explicitly implemented interface properties.
If you already have a PropertyInfo instance of the indexed property, then use the GetProperty(Object, PropertyInfo, ReflectionWays, Object) method for better performance.
If way is Auto, then this method uses the DynamicDelegate reflection way.
