NameDescription
System_CAPS_pubmethodNotImplementedException()

Initializes a new instance of the NotImplementedException class with default properties.

System_CAPS_protmethodNotImplementedException(SerializationInfo, StreamingContext)

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

System_CAPS_pubmethodNotImplementedException(String)

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

System_CAPS_pubmethodNotImplementedException(String, Exception)

Initializes a new instance of the NotImplementedException 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

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.)

NotImplementedException uses the default Equals implementation, which supports reference equality. For a list of initial values for an instance of NotImplementedException, see the NotImplementedException constructors.

The following example throws this exception for a method that has not been developed.

static void Main(string[] args)
{
    try
    {
        FutureFeature();
    }
    catch (NotImplementedException notImp)
    {
        Console.WriteLine(notImp.Message);
    }
}

static void FutureFeature()
{
    // Not developed yet.
    throw new NotImplementedException();
}
