如何在 user.config C# 中循环访问用户设置

Question

首先，我是个白痴，无法将问题格式化，所以我将不得不 post 这一切都在一个代码块中。我的程序中有以编程方式添加的设置。这些是这样添加的：

SettingsProperty SP = new SettingsProperty("LibImage" + AmountOfImages);
SP.PropertyType = typeof(string);
SP.DefaultValue = "goat";
SP.Provider = Settings.Default.Providers["LocalFileSettingsProvider"];
SP.Attributes.Add(typeof(UserScopedSettingAttribute), new UserScopedSettingAttribute());
Settings.Default.Properties.Add(SP);
Settings.Default.Reload();
Settings.Default.Save();
Settings.Default["LibImage" + AmountOfImages] = OFD.FileName;
MessageBox.Show(Settings.Default["LibImage" + AmountOfImages].ToString());

这些被添加到 user.config 并显示如下：

<setting name="LibImage1" serializeAs="String">
   <value>C:\Users\User\Background\Biggie.jpg</value>
</setting>
<setting name="LibImage2" serializeAs="String">
   <value>C:\Users\User\Background\BUSTA-RHYMES.jpg</value>
</setting>

当我重新启动程序时，我想将所有这些图像添加到面板中，如下所示：

int i = 0;
Settings.Default.Reload();
foreach (SettingsProperty P in Settings.Default.Properties)
{
    MessageBox.Show(P.Name);
    //part below not relevant for question
    if (P.Name.StartsWith("LibImage"))
    {
        i++;
        IMG = Image.FromFile(P.DefaultValue.ToString());
        PanelImgAr[AmountOfImages] = new SelectablePanel()
        {
                    Size = new Size(150, 84),
                    Location = new Point(0, -84 + (94 * i)),
                    BackgroundImage = IMG,
                    BackgroundImageLayout = ImageLayout.Stretch
        };
        PanelImgAr[AmountOfImages].Click += new EventHandler(SelectablePanel_Click);
        PanelImages.Controls.Add(PanelImgAr[AmountOfImages]);
    }
}

但是 MessageBox 没有给我任何名字。这可能是因为 Settings.Default.Properties 循环通过 App.config。谁能告诉我如何遍历 user.config？或者我如何将 user.config 中的设置添加到 App.config?

将 user.config 文件的完整路径解析为 XDoc。从这里开始，您可以将其作为字符数组读取。

 string path = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.PerUserRoamingAndLocal).FilePath;
        if (File.Exists(path))
        {
            XDocument XDoc = XDocument.Load(path);
            foreach (var node in XDoc.Nodes())
            {
                if (!string.IsNullOrEmpty(node.ToString()))
                {
                    string S = node.ToString();
                    string Word = "";
                    for (int i = 0; i < S.Length; i++)
                    {
                        if (IsAcceptedChar(S[i])) Word += S[i];
                        else
                        {
                            if (Word == "setting name")
                            {
