C#WIN编程!怎样获取TreeView中选中节点的值

在TreeView的AfterSelect事件中写代码即可。如下：

private void courseDetailTrv_AfterSelect(object sender, TreeViewEventArgs e)
{
string str = e.Node.Text ; // 这个语句可以取到节点的text
}

private void treeView1_AfterSelect(object sender, TreeViewEventArgs e)
{
//绑定选中项的值在TEXTBOX1中显示
//textBox1.Text = treeView1.SelectedNode.Text;
tbbmmc.Text = treeView1.SelectedNode.Text.Substring(2);
tbbmbm.Text = treeView1.SelectedNode.Text.Substring(0,2);
}

TreeView1.SelectedNode.Text

treeView1.SelectedNode.Text

就是TreeView1.SelectedNode.Text

TreeView1.SelectedNode.Text获取选中节点的值
