如何将下拉列表与ASP.NET中的字符串数组绑定? [英] How to bind drop down list with string array in ASP.NET?

问题描述

通过这样做，我能够将下拉列表与字符串数组绑定在一起(不确定这是否是正确的实现方式):

I am able to bind drop down list with a string array by doing so (not sure whether this is the correct way to implement):

string[] items = { "111", "222", "333" };
ddlSearch.DataSource = items;
ddlSearch.DataBind();

但是，我真正想要的是:当我单击下拉列表时，列表中显示的第一项应为 111 ，然后是 222 和333 .

However, what I actually wanted is: When I click the drop down list, the first item showing in the list shall be 111 followed by 222 and 333.

当我单击下拉列表按钮时，如何添加文本字符串以显示在下拉列表中?

How am I able to add the strings of text to show in the drop down list when I click the drop down list button?

Java有一种简单的方法来添加要显示在列表中的项目，但是我们如何在C#中做到这一点呢?(顺便说一下，我对C#还是很陌生.)

Java has an easy way to add items to be displayed in the list, but how do we do it in C#? (I am very new to C# by the way.)

推荐答案

使用 List< string>

标记可以是

<asp:DropDownList ID="DropDownList1" runat="server"></asp:DropDownList>

后端代码看起来像

var items = new List<string> {
"111",
"222",
"333"
};
items.Sort(); 

DropDownList1.DataSource = items;
DropDownList1.DataBind();
