The NotSupportedException type exposes the following members.
| 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(SerializationInfo, StreamingContext) | Initializes a new instance of the NotSupportedException class with serialized data. |
|
|
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. |
| Name | Description | |
|---|---|---|
|
Data | Gets a collection of key/value pairs that provide additional user-defined information about the exception. (Inherited from Exception.) |
|
|
HelpLink | Gets or sets a link to the help file associated with this exception. (Inherited from Exception.) |
|
HResult | Gets or sets HRESULT, a coded numerical value that is assigned to a specific exception. (Inherited from Exception.) |
|
|
InnerException | Gets the Exception instance that caused the current exception. (Inherited from Exception.) |
|
|
Message | Gets a message that describes the current exception. (Inherited from Exception.) |
|
|
Source | Gets or sets the name of the application or the object that causes the error. (Inherited from Exception.) |
|
|
StackTrace | Gets a string representation of the immediate frames on the call stack. (Inherited from Exception.) |
|
|
TargetSite | Gets the method that throws the current exception. (Inherited from Exception.) |
| Name | Description | |
|---|---|---|
|
|
Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
|
|
Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
|
|
GetBaseException | When overridden in a derived class, returns the Exception that is the root cause of one or more subsequent exceptions. (Inherited from Exception.) |
|
|
GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
|
|
GetObjectData | When overridden in a derived class, sets the SerializationInfo with information about the exception. (Inherited from Exception.) |
|
|
GetType |
Gets the runtime type of the current instance. (Inherited from Exception.) In XNA Framework 3.0, this member is inherited from Object.GetType(). In Portable Class Library Portable Class Library, this member is inherited from Object.GetType(). |
|
|
MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
|
|
ToString | Creates and returns a string representation of the current exception. (Inherited from Exception.) |
| Name | Description | |
|---|---|---|
|
SerializeObjectState | Occurs when an exception is serialized to create an exception state object that contains serialized data about the exception. (Inherited from Exception.) |
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 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.
