Remarks
There are methods that are not supported in the base class, with the expectation that these methods will be implemented in the derived classes instead. The derived class might implement only a subset of the methods from the base class, and throw NotSupportedException for the unsupported methods.
NotSupportedException is also thrown by System.IO classes whenever there is an attempt to read, seek, or write to a stream that does not support the invoked functionality. For example, after a call to Close, calling the various write methods will result in a NotSupportedException.
For scenarios where it is sometimes possible for the object to perform the requested operation, and the object state determines whether the operation can be performed, see InvalidOperationException.
NotSupportedException uses the HRESULT COR_E_NOTSUPPORTED, which has the value 0x80131515.
For a list of initial property values for an instance of NotSupportedException, see the NotSupportedException constructors.
