存储泛型List＆LT; CustomObject＆GT;使用ApplicationSettingsBase [英] Storing generic List<CustomObject> using ApplicationSettingsBase

问题描述

我想保存一个名单，其中，富＆GT;使用ApplicationSettingsBase，但是它只输出以下，即使列表是填充：

I am trying to save a List<Foo> using ApplicationSettingsBase, however it only outputs the following even though the list is populated:

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

富定义如下：

Foo is defined as follows:

[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;
    }
}

我怎样才能使ApplicationSettingsBase存储列表＆LT;富＆GT;

How can I enable ApplicationSettingsBase to store List<Foo>?

推荐答案

同意与托马斯Levesque的：

Agreed with Thomas Levesque:

下面的类被正确保存/回读：

The following class was correctly saved/read back:

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

    public string MashupString { get; set; }

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

请注意：我并不需要 SerializableAttribute

编辑：这里的XML输出​​：

here is the xml output:

<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>

和设置类我用：

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：

And at last the items I inserted:

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();
