结合字符串数组为DropDownList？

问题描述

这是我从来没有解决的问题。我将举例说明了两个代码样本，其中一个工作和其他不：

A question that I have never solved. I will illustrate with two code samples in which one works and the other doesn't:

Page_Load()
{
        FontFamily[] oFamilyFontList = FontFamily.Families;
        DropDownList_Fonts.DataSource = oFamilyFontList;
        DropDownList_Fonts.DataBind();

        string[] colorName = System.Enum.GetNames(typeof(KnownColor));
        DropDownList_FontColor.DataSource = colorName;
        DropDownList_FontColor.DataBind();
}

    <asp:DropDownList
        ID="DropDownList_Fonts" DataTextField="Name"
        DataValueField="Name" runat="server" >
    </asp:DropDownList>

    <asp:DropDownList
        ID="DropDownList_FontColor"  DataTextField="colorName"
        DataValueField="colorName" runat="server" >
    </asp:DropDownList>

第一个DropDownList填充没有任何错误很好，因为每个对象oFamilyFontList具有与结合属性名称在DataText和DataValue领域。

The first DropDownList populates fine without any errors because each object oFamilyFontList has a property 'Name' which binds with the DataText and DataValue fields.

第二个有没有在所有的属性，它只是一个字符串数组。什么可能我可以把两个领域内，使其工作？

The second one has no properties at all and it's just an array of strings. What possibly can I put inside both fields to make it work ?

推荐答案

是的，你可以绑定一个数组，但你必须删除 DataTextField 和 DataValueField 属性

Yes you can bind an array but you have to remove DataTextField and DataValueField attributes

<asp:DropDownList
        ID="DropDownList_FontColor"
        runat="server">
</asp:DropDownList>
