The NotSupportedException type exposes the following members.

Constructors

	Name	Description
	NotSupportedException() () () ()	Initializes a new instance of the NotSupportedException class, setting the Message property of the new instance to a system-supplied message that describes the error. This message takes into account the current system culture.
	NotSupportedException(String)	Initializes a new instance of the NotSupportedException class with a specified error message.
	NotSupportedException(String, Exception)	Initializes a new instance of the NotSupportedException class with a specified error message and a reference to the inner exception that is the cause of this exception.

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.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
