注册表的操作(C#)

注册表的操作：
得到系统的AppData/Roaming文件夹路径，这个值在注册表里面存储着的。可以用下面这个方法得到。
GetValueData("Software//Microsoft//Windows//CurrentVersion//Explorer//Shell
Folders", "AppData");

下面这个是得到默认的Roaming文件夹
return
GetINIPath().Substring(0, 9) + "Default//AppData//Roaming";
写入特定类型的键值。
RegistryKey
reg = Registry.CurrentUser.CreateSubKey(strKey);
RegistryValueKind
rvk = reg.GetValueKind(strValue);
reg.SetValue(strValue, strData, rvk);
这个函数是指定写入值得类型。strType值是string dword，跟注册表里面的键值类型一样。
switch (strType)
{
case "string":
reg.SetValue(strValue, strData, RegistryValueKind.String);
break;
case "dword":
reg.SetValue(strValue, strData, RegistryValueKind.DWord);
break;
default:
break;
}
strKey是对应的目录，strValue是对应的键名
string
idVal = string.Empty;
RegistryKey
reg = Registry.CurrentUser.OpenSubKey(strKey);
idVal =
reg.GetValue(strValue).ToString();
