c# winform 关于DataGridView的一些操作

private void Form1_Load(object sender, EventArgs e) 
{ 
            //创建RegistryKey实例 
            RegistryKey regkey = Registry.LocalMachine; 

            //使用OpenSubKey方法打开HKEY_LOCAL_MACHINE\SOFTWARE键 
            RegistryKey sys = regkey.OpenSubKey(@"SOFTWARE"); 

            //调用foreach语句读取HKEY_LOCAL_MACHINE\SOFTWARE键下的所有项目 
            foreach (string str in sys.GetSubKeyNames()) 
            { 
                //将输出的内容输出到RichTextBox控件里 
                richTextBox1.Text += str + "\n"; 
                
            } 
}
