C#操作windows注册表的方法

本文实例讲述了C#操作windows注册表的方法。分享给大家供大家参考。具体如下：

此代码演示了如何读取和写入注册表

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 "";
}

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 ; 
}

希望本文所述对大家的C#程序设计有所帮助。
