GetMemberBinder
Provides information about the object that called the dynamic operation. The binder.Name property provides the name of the member on which the dynamic operation is performed. For example, for the Console.WriteLine(sampleObject.SampleProperty) statement, where sampleObject is an instance of the class derived from the  class, binder.Name returns "SampleProperty". The binder.IgnoreCase property specifies whether the member name is case-sensitive.
Provides information about the object that called the dynamic operation . The binder . Name property provides the name of the member on which the dynamic operation is performed . For example for the Console . WriteLine ( sampleObject . SampleProperty ) statement where sampleObject is an instance of the class derived from the class binder . Name returns " SampleProperty " . The binder . IgnoreCase property specifies whether the member name is case - sensitive .
