为Registry.LocalMachine做排序 [英] do sorting for Registry.LocalMachine

问题描述

我有这个代码和我一起

i have this code with me

protected void Page_Load(object sender, EventArgs e)
{
    string uninstallKey = @"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall";
    using (RegistryKey rk = Registry.LocalMachine.OpenSubKey(uninstallKey))
    {
        foreach (string skName in rk.GetSubKeyNames())
        {
            using (RegistryKey sk = rk.OpenSubKey(skName))
            {
                    this.Label1.Text += Convert.ToString(sk.GetValue("DisplayName")) + "</br>";
            }
        }
    }
}

它运行正常，并返回预期结果。但是如何根据DisplayName进行排序？

it works fine, and return the expected result. but how can i do the sorting according to "DisplayName"?

推荐答案

看看以下是否有效。你需要使用语句将System.Linq添加到你的文件中。

See if the following works. Youll need to add System.Linq using statement to your file.

string uninstallKey = @"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall";
            using (RegistryKey rk = Registry.LocalMachine.OpenSubKey(uninstallKey))
            {
                string value = rk.GetSubKeyNames().Select(skName => rk.OpenSubKey(skName)).Where(m => m.GetValue("DisplayName") != null).OrderBy(m => m.GetValue("DisplayName")).Aggregate<RegistryKey, string>(null, (current, sk) => current + (Convert.ToString(sk.GetValue("DisplayName")) + "</br>"));
                Console.WriteLine(value);
            }

它获取价值，我不知道它是否是你想要的但是它似乎是在向我订购我理解正确。

It gets values, i have no idea if its what you want but it appears to be ordering to me if i understood you correctly.
