示例

下面的示例创建一个具有属性和子元素的元素。The following example creates an element with attributes and child elements. 然后,它调用此方法以删除属性和子元素。It then calls this method to remove both the attributes and the child elements.

XElement root = new XElement("Root",  
    new XAttribute("Att1", 1),  
    new XAttribute("Att2", 2),  
    new XAttribute("Att3", 3),  
    new XElement("Child1", 1),  
    new XElement("Child2", 2),  
    new XElement("Child3", 3)  
);  
root.RemoveAll();   // removes children elements and attributes of root  
Console.WriteLine(root);  
Dim root As XElement = _   
        <Root Attr1="1" Attr2="2" Attr3="3">  
            <Child1>1</Child1>  
            <Child2>2</Child2>  
            <Child3>3</Child3>  
        </Root>  
  
root.RemoveAll()   ' removes children elements and attributes of root  
Console.WriteLine(root)  

该示例产生下面的输出:This example produces the following output:
