我正在尝试保存列表< Foo>使用ApplicationSettingsBase,但即使填充了列表,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< Foo>？
解决方法
同意Thomas Levesque：
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>
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();
