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();

}

}

}
