 //
 // Summary:
 //     Provides the implementation for operations that get a value by index. Classes
 //     derived from the System.Dynamic.DynamicObject class can override this method
 //     to specify dynamic behavior for indexing operations.
 //
 // Parameters:
 //   binder:
 //     Provides information about the operation.
 //
 //   indexes:
 //     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:
 //     The result of the index operation.
 //
 // Returns:
 //     true if the operation is successful; otherwise, false. If this method returns
 //     false, the run-time binder of the language determines the behavior. (In most
 //     cases, a run-time exception is thrown.)
