语法

声明
Public Overridable Sub Update ( _
    ByRef ObjectXml As String _
)

public virtual void Update (
    ref string ObjectXml
)

public:
virtual void Update (
    String^% ObjectXml

JScript 不支持由引用传递值类型参数。

参数

  • ObjectXml
    A string that contains the XML of the old object.

备注

The runtime calls CanUpdate on new objects and passes in the GUID of the old object. If the new object can update the old object, the old object is passed to the new one through the Update method, where the XML is changed.

By default, all extensible objects implement CanUpdate to return false and implement the Update method to do nothing on the XML it is given in its parameters.
