将字符串截取

string[] strlist = str.Split(',');

遍历TreeNode父节点 [TreeView1.Nodes]

foreach (TreeNode rhp in TreeView1.Nodes)

{


遍历字符串每一项与TreeNode子父节点value对比，值相等该节点选中

foreach (string strguid in strlist)

{

if (rhp.Value == strguid.ToLower())

{

rhp.Checked = true;

}

遍历TreeNode子节点
[rhp.ChildNodes]

foreach (TreeNode rhp1 in rhp.ChildNodes)

{

if (rhp1.Value == strguid.ToLower())

{

rhp1.Checked = true;

}

}

}

}
