[ComVisibleAttribute(true)]
public class InvalidOperationException : SystemException

NameDescription
System_CAPS_pubmethodInvalidOperationException()

Initializes a new instance of the InvalidOperationException class.

System_CAPS_protmethodInvalidOperationException(SerializationInfo, StreamingContext)

Initializes a new instance of the InvalidOperationException class with serialized data.

System_CAPS_pubmethodInvalidOperationException(String)

Initializes a new instance of the InvalidOperationException class with a specified error message.

System_CAPS_pubmethodInvalidOperationException(String, Exception)

Initializes a new instance of the InvalidOperationException class with a specified error message and a reference to the inner exception that is the cause of this exception.

NameDescription
System_CAPS_pubpropertyData

Gets a collection of key/value pairs that provide additional user-defined information about the exception.(Inherited from Exception.)

System_CAPS_pubpropertyHelpLink

Gets or sets a link to the help file associated with this exception.(Inherited from Exception.)

System_CAPS_pubpropertyHResult

Gets or sets HRESULT, a coded numerical value that is assigned to a specific exception.(Inherited from Exception.)

System_CAPS_pubpropertyInnerException

Gets the Exception instance that caused the current exception.(Inherited from Exception.)

System_CAPS_pubpropertyMessage

Gets a message that describes the current exception.(Inherited from Exception.)

System_CAPS_pubpropertySource

Gets or sets the name of the application or the object that causes the error.(Inherited from Exception.)

System_CAPS_pubpropertyStackTrace

Gets a string representation of the immediate frames on the call stack.(Inherited from Exception.)

System_CAPS_pubpropertyTargetSite

Gets the method that throws the current exception.(Inherited from Exception.)

NameDescription
System_CAPS_pubmethodEquals(Object)

Determines whether the specified object is equal to the current object.(Inherited from Object.)

System_CAPS_protmethodFinalize()

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)

System_CAPS_pubmethodGetBaseException()

When overridden in a derived class, returns the Exception that is the root cause of one or more subsequent exceptions.(Inherited from Exception.)

System_CAPS_pubmethodGetHashCode()

Serves as the default hash function. (Inherited from Object.)

System_CAPS_pubmethodGetObjectData(SerializationInfo, StreamingContext)

When overridden in a derived class, sets the SerializationInfo with information about the exception.(Inherited from Exception.)

System_CAPS_pubmethodGetType()

Gets the runtime type of the current instance.(Inherited from Exception.)

System_CAPS_protmethodMemberwiseClone()

Creates a shallow copy of the current Object.(Inherited from Object.)

System_CAPS_pubmethodToString()

Creates and returns a string representation of the current exception.(Inherited from Exception.)

NameDescription
System_CAPS_proteventSerializeObjectState

Occurs when an exception is serialized to create an exception state object that contains serialized data about the exception.(Inherited from Exception.)

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:

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

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

  • XContainer.Add, if the object or objects to be added would result in an incorrectly structured XML document.

To determine the precise cause of the exception, consult the exception information and the exception message for the method call that throws the exception.

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.
