Converting an object to a specified type. Return dictionary.TryGetValue(binder.Name, out result) GetMemberBinder binder, out object result) Public class DynamicNumber : DynamicObject If you try to convert an object to any other type, a run-time exception is thrown. In this example, only conversion to strings and integers is supported. It also overrides the TrySetMember and TryGetMember methods to enable access to the data elements. DynamicNumber overrides the Tr圜onvert method to enable type conversion. The following code example demonstrates the DynamicNumber class, which is derived from the DynamicObject class.

(In most cases, a language-specific run-time exception is thrown.) ExamplesĪssume that you need a data structure to store textual and numeric representations of numbers, and you want to define conversions of this data structure to strings and integers. If this method returns false, the run-time binder of the language determines the behavior. True if the operation is successful otherwise, false. The result of the type conversion operation.
