写出来，方便记忆，以后要用，可以直接改改就能用。
复制代码 代码如下:
using System;
namespace Backend
{
public class RegistryStorage
{
public static PageVisibility OpenAfterStart()
{
Microsoft.Win32.RegistryKey registryKey;
PageVisibility visibility = PageVisibility.Visible;
// HKCUSoftwareRegeditStorage
registryKey = Microsoft.Win32.Registry.CurrentUser.OpenSubKey(@"SoftwareRegistryStorage");
if (registryKey != null)
{
visibility = (string)registryKey.GetValue("PageVisibility") == PageVisibility.Hide.ToString() ?
PageVisibility.Hide : PageVisibility.Visible;
registryKey.Close();
}
return visibility;
}
public static void SaveBeforeExit(PageVisibility visibility)
{
Microsoft.Win32.RegistryKey registryKey;
// HKCUSoftwareRegeditStorage
registryKey = Microsoft.Win32.Registry.CurrentUser.CreateSubKey(@"SoftwareRegistryStorage");
registryKey.SetValue("PageVisibility", visibility.ToString());
registryKey.Close();
}
}
public enum PageVisibility
{
Visible,
Hide
}
}
代码很容易理解，下面添加一点代码来测试一下。
复制代码 代码如下:
using System;
using System.Diagnostics;
namespace Backend.Test
{
class Program
{
static void Main(string[] args)
{
// 存值
RegistryStorage.SaveBeforeExit(PageVisibility.Hide);
// 取值
PageVisibility visibility = RegistryStorage.OpenAfterStart();
// 验证
Debug.Assert(visibility == PageVisibility.Hide);
// 存值
RegistryStorage.SaveBeforeExit(PageVisibility.Visible);
// 取值
visibility = RegistryStorage.OpenAfterStart();
// 验证
Debug.Assert(visibility == PageVisibility.Visible);
Console.WriteLine("Press any key to exit.");
Console.ReadKey();
}
}
}
