DuplicateKeyPropertyException Class

An exception that is thrown when a persistent object has two or more key properties.

Namespace : DevExpress.Xpo.Exceptions

Assembly : DevExpress.Xpo.v25.2.dll

NuGet Package : DevExpress.Xpo

Declaration

• C#
• VB.NET

public class DuplicateKeyPropertyException :
    Exception

Public Class DuplicateKeyPropertyException
    Inherits Exception

Remarks

This exception is thrown whenever a class with multiple key property definitions is used.

Solution:

• declare only one key property in a persistent object;

• for classes derived from the XPObject class do not declare key properties, as the XPObject already contains the XPObject.Oid key property.
