//1.向注册表中写信息

using (RegistryKey key = Registry.LocalMachine.OpenSubKey(@"", true))

{

　　if (key == null)

　　{

　　　　using (RegistryKey myKey = Registry.LocalMachine.CreateSubKey(@"SOFTWARE\EricSun\MyTestKey"))

　　　　{

　　　　　　myKey.SetValue("MyKeyName", "Hello EricSun." + DateTime.Now.ToString());

　　　　}

　　}

　　else

　　{

　　　　key.SetValue("MyKeyName", "Hello EricSun." + DateTime.Now.ToString());

　　}

}

 

//2.读取信息(IIS也可以正常读取)

protected string GetRegistryValue(string path, string paramName)

{

　　string value = string.Empty;

      RegistryKey root = Registry.LocalMachine;

      RegistryKey rk = root.OpenSubKey(path);

      if (rk != null)

      {

      　　value = (string)rk.GetValue(paramName, null);

      }

      return value;

}

string value = GetRegistryValue("SOFTWARE\\EricSun\\MyTestKey", "MyKeyName");

Response.Write(value);
