首先分享一下写入，这个最常用的
public bool WriteRegedit(){
try
{
RegistryKey rk = Registry.CurrentUser;
RegistryKey softWare = rk.OpenSubKey("Software");
RegistryKey microsoft = softWare.OpenSubKey("Microsoft");
RegistryKey windows = microsoft.OpenSubKey("Windows");
RegistryKey current = windows.OpenSubKey("CurrentVersion");
RegistryKey explorer = current.OpenSubKey("Explorer");
RegistryKey shell = explorer.OpenSubKey(@"Shell Folders", true);//这里必须加true就是得到写入权限
RegistryKey key = shell.CreateSubKey("swort");//创建swort目录
key.SetValue("swort", "test");
//在swort目录下建立写入swort test
Response.Write("写入成功！！！！！！！！！");
return true;
}
catch
{
return false;
} 接下来是给出一个操作网页的cs文件，大家看着调用就行

ReadRegedit();
Response.Write("<br/>");
Response.Write("这里将要写入信息swort/swort-test" + "<br/>");
