读取文本文件

Question

 
private void treeView1_NodeMouseDoubleClick(object sender, TreeNodeMouseClickEventArgs e)
        {            if (e.Node.ImageIndex == 7)
            {
                Text_Edit TE = new Text_Edit();
                TE.ShowDialog();
                TE.text_content.Text = File.ReadAllText(path, Encoding.UTF8);
                
            }
        }
代码实现的是 双击节点 出现Text_Edit.cs 窗口 里面有text_content （textbox）控件
想在text_content空间中读取path路径的文本
并且触发text_content_TextChanged事件

Answer 1

            text_content.TextChanged += new EventHandler(text_content_TextChangnged);
        }        private void text_content_TextChangnged(object sender, EventArgs e)
        {        }

Answer 2

加事件
text_content.TextChanged += new EventHandler(text_content_TextChangnged);
  双击节点
   text_content.Text=","+text_content.Text;        private void text_content_TextChangnged(object sender, EventArgs e)
        {
            if(text_content.Text.StartsWith(",")){
                text_content.Text=text_content.Text.Substring(1);return;
             }
        }
