在VS2010集合编辑器中编辑字符串集合

因为我所有的疑虑都在这里消失了......:)我还有另一个问题。

我有一个自定义控件，其中有一个字符串列表列表，我希望控件的用户能够在属性编辑器中编辑列表，但我不起作用。我可以单击按钮来使集合编辑器可见，但添加键未启用，并且显示一条消息“属性编辑不可用”。

我做了一个定制的快速而肮脏的课程

    public class DataUrl
{
    public string Url {get; set;}
    public DataUrl() { }
    public override string ToString()
    {
        return Url.ToString();
    }
}

，用这个它可以工作，但它...... 我怀疑它不起作用，因为字符串（或字符串）没有无参数构造函数。我也尝试过使用该属性

[NewItemTypesAttribute(typeof(string))]

但毫无价值.. 有人可以帮助我吗？

As all my my doubts are used to vanish here... :) I have got an other question.

I have a custom control in which I have a list of strings List and I'd like the user of my control to be able to edit the list in the properties editor but I doesn't work.. I can click on the button to make the Collection editor visible but the add key is not enabled and there's a message 'Property editing is not available'.

I made a custom quick and dirty class

    public class DataUrl
{
    public string Url {get; set;}
    public DataUrl() { }
    public override string ToString()
    {
        return Url.ToString();
    }
}

and with this it works but its...
I suspect it doesn't work because string (or String) does not have a parameter-less constructor. I also tried to use the attribute

[NewItemTypesAttribute(typeof(string))]

but worthless..
Could someone help me ?
