Properties

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 frames on the call stack at the time the current exception was thrown. (Inherited from Exception.)

Methods

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 the Object 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.)
GetType Gets the runtime type of the current instance. (Inherited from Exception.)
MemberwiseClone Creates a shallow copy of the current Object. (Inherited from Object.)

Remarks

InvalidOperationException is used in cases when the failure to invoke a method is caused by reasons other than invalid arguments. For example, InvalidOperationException is thrown by:

  • MoveNext if objects of a collection are modified after the enumerator is created.

  • GetString if the resource set is closed before the method call is made.

If the method invocation failure is due to invalid arguments, then ArgumentException or one of its derived classes, ArgumentNullException or ArgumentOutOfRangeException, should be thrown instead.

  • The Ldflda Microsoft intermediate language (MSIL) instruction throws InvalidOperationException.

InvalidOperationException uses the HRESULT COR_E_INVALIDOPERATION, which has the value 0x80131509.

For a list of initial property values for an instance of InvalidOperationException, see the InvalidOperationException constructors.
