c# - 使用 ApplicationSettingsBase 存储通用 List

Question

我正在尝试使用 ApplicationSettingsBase 保存一个 List ，但是即使列表已填充，它也只输出以下内容:

<setting name="Foobar" serializeAs="Xml">
    <value />
</setting>

Foo 定义如下:

[Serializable()]
public class Foo
{
    public String Name;
    public Keys Key1;
    public Keys Key2;

    public String MashupString
    {
        get
        {
            return Key1 + " " + Key2;
        }
    }

    public override string ToString()
    {
        return Name;
    }
}

如何启用 ApplicationSettingsBase 来存储 List ？

Answer 1

同意 Thomas Levesque 的观点:

以下类已正确保存/读回:

public class Foo
{
    public string Name { get; set; }

    public string MashupString { get; set; }

    public override string ToString()
    {
        return Name;
    }
}

注意:我不需要SerializableAttribute。

编辑:这是 xml 输出:

<WindowsFormsApplication1.MySettings>
    <setting name="Foos" serializeAs="Xml">
        <value>
            <ArrayOfFoo xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                xmlns:xsd="http://www.w3.org/2001/XMLSchema">
                <Foo>
                    <Name>Hello</Name>
                    <MashupString>World</MashupString>
                </Foo>
                <Foo>
                    <Name>Bonjour</Name>
                    <MashupString>Monde</MashupString>
                </Foo>
            </ArrayOfFoo>
        </value>
    </setting>
</WindowsFormsApplication1.MySettings>

以及我使用的设置类:

sealed class MySettings : ApplicationSettingsBase
{
    [UserScopedSetting]
    public List<Foo> Foos
    {
        get { return (List<Foo>)this["Foos"]; }
        set { this["Foos"] = value; }
    }
}

最后我插入的项目:

private MySettings fooSettings = new MySettings();

var list = new List<Foo>()
{
    new Foo() { Name = "Hello", MashupString = "World" },
    new Foo() { Name = "Bonjour", MashupString = "Monde" }
};

fooSettings.Foos = list;
fooSettings.Save();
fooSettings.Reload();
