C#操作服务器（2）：C#实现对注册表项的创建和读写操作

通过C#设置（如果不存在则创建）或获取（不存在则返回空字符串）注册表项的值。

/// 

/// 设置注册表项的值
/// 
///起始项
///子项路径
///字符串值项目的名称
///字符串值项目的名称
public void SetRegeditValue(RegistryKey startKey, string subKeyPath, string strItemName, string strItemValue)
{
    RegistryKey subKey = startKey.OpenSubKey(subKeyPath, true);
    if (subKey==null)
    {
        subKey = startKey.CreateSubKey(subKeyPath);
    }
    subKey.SetValue(strItemName, strItemValue);
}

/// 

/// 获取注册表项的值
/// 
///起始项
///子项路径
///字符串值项目的名称
public string GetRegeditValue(RegistryKey startKey, string subKeyPath, string strItemName)
{
    RegistryKey subKey = startKey.OpenSubKey(subKeyPath, false);
    if (subKey == null)
    {
        return "";
    }
    object obj = subKey.GetValue(strItemName);
    return obj==null?"":obj.ToString();
}

调用示例：

RegistryKey key = Microsoft.Win32.Registry.LocalMachine

SetRegeditValue(key,@"SOFTWARE\Kinglong\IprogramCMS","UserName","king");

string userName =GetRegeditValue(key,@"SOFTWARE\Kinglong\IprogramCMS","UserName");
