这是xml文件，我要做的是：
1、输入任何一个节点的Name，把它一层的孩子节点都取出，输出到屏幕。
2、输入type类型，把同类型的节点全部取出，输出到屏幕。
3、输入type和name，生成一个新的节点，在指定Name下面作为孩子存在。
求高手帮助！

控制台应用程序中测试
static void Main(string[] args)
{
XmlDocument xd = new XmlDocument();
xd.Load("XMLFile1.xml");

Console.WriteLine("根据节点的Name查找，请输入Name:");
string name = Console.ReadLine().Trim();
XmlNode xn = xd.SelectSingleNode("//TreeNode[@name='" + name + "']");
if (xn != null)
{
Console.WriteLine(xn.OuterXml);
}

Console.WriteLine("\n根据节点的type查找，请输入type:");
string type = Console.ReadLine().Trim();
XmlNodeList xnl1 = xn.SelectNodes("//TreeNode[@type='" + type + "']");
foreach (XmlNode xni in xnl1)
{
Console.WriteLine(string.Format("\n<TreeNode type=\"{0}\" id=\"{1}\" name=\"{2}\" security=\"{3}\" property=\"{4}\">", xni.Attributes["type"].Value, xni.Attributes["id"].Value, xni.Attributes["name"].Value, xni.Attributes["security"].Value, xni.Attributes["property"].Value));
}

Console.WriteLine("\n输入type与name创建新节点\n请输入type:");
string ctype = Console.ReadLine().Trim();
Console.WriteLine("\n输入name:");
string cname = Console.ReadLine().Trim();
XmlNode fxd = xd.SelectSingleNode("//TreeNode[@name='" + name + "']");
if (fxd == null)
{
Console.WriteLine(string.Format("\nname为{0}的节点不存在，创建节点失败!", cname));
Console.ReadLine();
}
else
{
XmlElement xe=xd.CreateElement("TreeNode");
xe.SetAttribute("type",ctype);
fxd.AppendChild(xe);
xd.Save("XMLFile1.xml");
}
}
