C# C.Net使用Settings.Settings保存列表视图

我正在尝试使用C.Net保存和加载ListView列表的内容。我希望通过创建变量System.Windows.Forms.ListView来保存它，然后用它填充它

用于保存的代码段：

Properties.Settings.Default.followedUsersSettings = followerList;
Properties.Settings.Default.Save();

用于加载的代码段：

if (Properties.Settings.Default.followedUsersSettings != null) {
            followerList = Properties.Settings.Default.followedUsersSettings;
        }

//check for null (first run)
if (Properties.Settings.Default.followedUsersSettings != null) {
    //create a new collection again
    StringCollection collection = new StringCollection();
    //set the collection from the settings variable
    collection = Properties.Settings.Default.followedUsersSettingsCollection;
    //convert the collection back to a list
    List<string> followedList = collection.Cast<string>().ToList();
    //populate the listview again from the new list
    foreach (var item in followedList) {
        followerListView.Items.Add(item);
    }
}

我似乎无法使用该代码使其工作。有没有更好的方法尽可能简单地保存这些信息？列表是单列的，所以数组也应该可以工作，但我不确定推荐什么。

好的，我设法让它工作了

if (Properties.Settings.Default.followedUsersSettingsListView == null)
{
    // adding default items to settings 
    Properties.Settings.Default.followedUsersSettingsListView = new System.Collections.Specialized.StringCollection();
    Properties.Settings.Default.followedUsersSettingsListView.AddRange(new string [] {"Item1", "Item2"});
    Properties.Settings.Default.Save();
}
// load items from settings 
followerList.Items.AddRange((from i in Properties.Settings.Default.followedUsersSettingsListView.Cast<string>()
                                    select new ListViewItem(i)).ToArray());

保存：

//Convert the listview to a normal list of strings
var followerList = new List<string>();

//add each listview item to a normal list

foreach (ListViewItem Item in followerListView.Items) {
     followerList.Add(Item.Text.ToString());
}

//create string collection from list of strings
StringCollection collection = new StringCollection();

//set the collection setting (created in Settings.settings as a specialized collection)
Properties.Settings.Default.followedUsersSettingsCollection = collection;
//persist  the settings
Properties.Settings.Default.Save();

装载时：

if (Properties.Settings.Default.followedUsersSettings != null) {
            followerList = Properties.Settings.Default.followedUsersSettings;
        }

//check for null (first run)
if (Properties.Settings.Default.followedUsersSettings != null) {
    //create a new collection again
    StringCollection collection = new StringCollection();
    //set the collection from the settings variable
    collection = Properties.Settings.Default.followedUsersSettingsCollection;
    //convert the collection back to a list
    List<string> followedList = collection.Cast<string>().ToList();
    //populate the listview again from the new list
    foreach (var item in followedList) {
        followerListView.Items.Add(item);
    }
}

什么是followerList？内容是什么？只是字符串列表还是有子项？@TaW内容只是使用System.Windows.Forms.Listview的简单字符串列表。没有子项什么是followerList？内容是什么？只是字符串列表还是有子项？@TaW内容只是使用System.Windows.Forms.Listview的简单字符串列表。没有子项，可能应该更好地命名我的变量。followerList是表单上显示的列表视图。FollowedUserSettingsListView是设置中使用的变量的名称。SettingsOry可能应该更好地命名我的变量。followerList是表单上显示的列表视图。FollowedUserSettingsListView是设置中使用的变量的名称。Settings但是当集合变量为空时，您不安全，是吗？但是当集合变量为空时，您不安全，是吗？
