InvalidOperationException Class
The exception that is thrown when a method call is invalid for the object's current state.
Assembly: mscorlib (in mscorlib.dll)
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.
