答

其中一种解决方案可以基于 XDocument .检查示例，其中添加了一些项目:

One of the solutions can be based on XDocument. Check an example, which adds some items:

string sample = @"<data><id></id><list></list></data>";

XDocument doc = XDocument.Parse( sample );

Console.WriteLine("--- Initial XML:");
Console.WriteLine(doc.ToString(SaveOptions.None));


var list = doc.Root.Element( "list" );

// add some items
for(int i = 1; i <= 4; ++i )
{
	string sample_value = i.ToString();
	list.Add( new XElement( "item", sample_value ) );
}


Console.WriteLine("--- Result:");
Console.WriteLine(doc.ToString(SaveOptions.None));

为简单起见，它从字符串中加载XML.为了处理文件，请使用 XDocument.Load 和 Save .

For simplicity, it loads XML from string. In order to deals with files, use XDocument.Load and Save.
