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();
