Adds a named code entity or type mapping to the System.Xml.Serialization.CodeIdentifiers instance's scope, ensuring that the name is unique within the scope.
![]()
The identifier parameter value or a modified string if there is a name collision.
If the identifier parameter value is not unique within the System.Xml.Serialization.CodeIdentifiers instance's scope, a new, unique string is generated and used in its place. The new string is generated by appending to the input name. The original name is not unique if it was passed previously to the CodeIdentifiers.Add(string, object), CodeIdentifiers.AddUnique(string, object), or CodeIdentifiers.AddReserved(string) method, or if it was generated by a previous call to the CodeIdentifiers.AddUnique(string, object) method. In each case, if the new identifier is not unique, it is first passed to the CodeIdentifiers.MakeUnique(string) method to create a new unique identifier.
If you want to control the names of code entities that are bound to XML Schema or Web service definitions, use the associated attributes rather than creating an instance of the System.Xml.Serialization.CodeIdentifiers class. For a complete list, see Attributes That Control XML Serialization.
