從 C# 中的注冊表中刪除與文件擴展名關聯的圖標

Question

我使用這樣的方法將文件擴展名與圖標相關聯：

public static void Associate(string extension, string progID, string description, string icon, string application)
{
    Registry.ClassesRoot.CreateSubKey(extension)?.SetValue("", progID);
    if (!string.IsNullOrEmpty(progID))
    {
        using var key = Registry.ClassesRoot.CreateSubKey(progID);
        if (description != null)
            key?.SetValue("", description);
        if (icon != null)
            key?.CreateSubKey("DefaultIcon")?.SetValue("", ToShortPathName(icon));
        if (application != null)
            key?.CreateSubKey(@"Shell\Open\Command")?.SetValue("", ToShortPathName(application) + " \"%1\"");
    }
}

當我想完全刪除我關聯的文件擴展名時，我不知道如何繼續。 為此，我嘗試了這樣的事情：

public static void Remove(string progID)
{
    Registry.ClassesRoot.DeleteSubKey(progID);
}

它給出了這樣的錯誤：

注冊表有子項，此方法不支持遞歸刪除。

它在這個地址有一個解決方案： https://www.codeproject.com/Articles/3389/Read-write-and-delete-from-registry-with-C

像這樣：

public static RegistryKey BaseRegistryKey { get; set; } = Registry.LocalMachine;
public static string subKey { get; set; } = "SOFTWARE\\" + Application.ProductName.ToUpper();

public bool DeleteSubKeyTree()
{
    try
    {
        // Setting
        RegistryKey rk = baseRegistryKey ;
        RegistryKey sk1 = rk.OpenSubKey(subKey);
        // If the RegistryKey exists, I delete it
        if ( sk1 != null )
            rk.DeleteSubKeyTree(subKey);

        return true;
    }
    catch (Exception e)
    {
        // AAAAAAAAAAARGH, an error!
        MessageBox.Show(e, "Deleting SubKey " + subKey);
        return false;
    }
}
