我想在我的web.config中有一个自定义部分,如下所示：
<MyMainSection attributeForMainSection = "value foo">
<add name = "foo"
type = "The.System.Type.Of.Foo,Assembly,Qualified Name Type Name" />
<add name = "bar"
type = "The.System.Type.Of.Bar,Qualified Name Type Name" />
</MyMainSection>
我已经定义了以下代码：
using System.Configuration;
class MyMainSection : ConfigurationSection
{
/*I've provided custom implemenation.
Not including it here for the sake of brevity. */
[ConfigurationProperty("attributeForMainSection")]
public string AttributeForMyMainSection { get; set; }
[ConfigurationProperty("add")]
public AddElement TheAddElement { get; set; }
private class AddElement: ConfigurationElement
{
/* Implementation done */
}
}
此属性TheAddElement应该是IEnumerable< AddElement>或者只是AddElement,如果我想允许多个添加元素？
解决方法
也没有,你会引入一个新的
ConfigurationCollectionElement,例如
部分
class MyMainSection : ConfigurationSection
{
[ConfigurationProperty("",Isrequired=true,IsDefaultCollection=true)]
public AddElementCollection Instances
{
get { return (AddElementCollection) this[""]; }
set { this[""] = value; }
}
}
采集
public class AddElementCollection : ConfigurationElementCollection
{
protected override ConfigurationElement CreateNewElement()
{
return new AddElement();
}
protected override object GetElementKey(ConfigurationElement element) {
return ((AddElement) element).Name;
}
}
元件
private class AddElement: ConfigurationElement
{
[ConfigurationProperty("name",IsKey=true,Isrequired=true)]
public string Name
{
get { return (string) base["name"]; }
set { base["name"] = value;
}
...
}
