Parameters

expression
Type: System.CodeDom.CodeExpression
A CodeExpression object that indicates the expression for which to generate code.

ExceptionCondition
NotImplementedException

Neither this method nor the CreateGenerator method is overridden in a derived class.

NoteNote

In the .NET Framework versions 1.0 and 1.1, this method is provided by the ICodeGenerator implementation that is returned by the CreateGenerator method of the provider. In version 2.0, this method can be called directly on the code provider even if it is not overridden by the code provider. If the code provider does not override this method, the ICodeGenerator implementation is called by the base class.

Notes to Inheritors

If you override this method, you must not call the corresponding method of the base class. The base-class method creates a generator in the derived class using the obsolete CreateGenerator method for compatibility with preexisting providers that use code generators. The base-class method then calls the equivalent method in the ICodeGenerator implementation to perform this function. You will get a NotImplementedException if you call the base-class method from a code provider that does not use a code generator.
