C#读取xml文件数据。显示在datagridview控件问题

如上图所示框起来的是xml文件的一个子节点内容，这个子节点中包括了不同结构的子节点数据。可以仔细看下这个xml结构，现在我想把这个节点的数据按照下面的格式显示在文本框以及datagridview中。其他同等节点类似，具体代码该怎么写呢？

大概看了下
public NodeCollections Children
{
get
{
var sub = _base.ChildNodes.Cast().FirstOrDefault(x => x.Name == "SUB-ELEMENTS");
if (sub == null)
sub = _base.ChildNodes.Cast().FirstOrDefault(x => x.Name == "ELEMENTS");
return new NodeCollections(sub);
}
}
如果你要加载Tuner，这里要加上EVENTS
if (sub == null)
sub = _base.ChildNodes.Cast().FirstOrDefault(x => x.Name == "EVENTS");
就写在Children的subelements后面
