读取注册表

   private string  GetRegistShellData(string RegistName)
        {
            try
            {
                string registData, SubregistData;
                RegistryKey hkml = Registry.LocalMachine;
                RegistryKey software = hkml.OpenSubKey(@"SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon", true);
                registData = software.GetValue(RegistName).ToString();
                SubregistData = registData.Substring(0, 2);
                return SubregistData;
            }
            catch (Exception excp)
            {
                MessageBox.Show("GetRegistShellData错误" + excp.ToString(), "错误", MessageBoxButtons.OK, MessageBoxIcon.Warning);
            }
            return "";
        }
 
        /// <summary>
 

写入注册表

private void  RenameRegistData() 
{ 
    try 
    { 
        string registData1; 
        RegistryKey hkml = Registry.LocalMachine; 
        RegistryKey software2 = hkml.OpenSubKey(@"SOFTWARE\"+ Shadowin + @"\SysToolSign", true); 
        registData1 = software2.GetValue("Sign").ToString(); 
   
        software2.SetValue("Sign", "1"); 
        registData1 = software2.GetValue("Sign").ToString(); 
    } 
    catch (Exception excp) 
    { 
        MessageBox.Show("RenameRegistData错误" + excp.ToString(), "错误", MessageBoxButtons.OK, MessageBoxIcon.Warning); 
    } 
    return ; 
}
