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。
