Provides the implementation for operations that get a value by index. Classes derived from the DynamicObject class can override this method to specify dynamic behavior for indexing operations.

function TryGetIndex(binder, indexes, result);Parameters
- binder GetIndexBinder
- Provides information about the operation.
- indexes Object
- The indexes that are used in the operation. For example, for the sampleObject[3] operation in C# (sampleObject(3) in Visual Basic), where sampleObject is derived from the DynamicObject class, indexes[0] is equal to 3.
- result Object
- The result of the index operation.
Return Value
Booleanif the operation is successful; otherwise, . If this method returns , the run-time binder of the language determines the behavior. (In most cases, a run-time exception is thrown.)
