定义

重载

示例

以下示例创建一个具有三个属性的 元素。 然后，它使用此方法将元素的所有属性替换为单个属性。

XElement root = new XElement("Root",
    new XAttribute("Att1", 1),
    new XAttribute("Att2", 2),
    new XAttribute("Att3", 3)
);
root.ReplaceAttributes(
    new XAttribute("NewAtt1", 101)
);
Console.WriteLine(root);

Dim root As XElement = <Root Att1="1" Att2="2" Att3="3"/>
root.ReplaceAttributes(New XAttribute("NewAtt1", 101))
Console.WriteLine(root)

该示例产生下面的输出：

<Root NewAtt1="101" />

注解

此方法将引发 Changed 和 Changing 事件。
