Question

用List<string>如何绑定DropdownList

需求是将数据库中的两列数据存放到List<string>对象中，然后绑定到dropdownlist上，一列是Value，一列是text。
请问如何实现？

Answer 1

yissyo的应该可以!
既然有value,有text. 一个string怎么够呢！ 你可以把value和text封装成一个类(class1)嘛！ 对应的给个属性Value和Text!
List<class1> cList=new List<class1>();

ddl.DataSource = cList;
ddl.DataTextField = cList.Value;
ddl.DataValueField = cList.Text;
ddl.DataBind();

Answer 2

List<string> datas1 = new List<string>();
List<string> datas2 = new List<string>();
datas1.Add("abc");
datas2.Add("123");
datas2.Add("1bd");

Dictionary<string, string> dic = new Dictionary<string, string>();
for (int i = 0; i < datas1.Count && i < datas2.Count; ++i)
{
dic.Add(datas1[i], datas2[i]);
}

DropDownList1.DataSource = dic;
DropDownList1.DataTextField = "Key";
DropDownList1.DataValueField = "Value";
DropDownList1.DataBind();

Answer 3

List<string>是一维数据完成不了你的任务，
考虑用Dictionary<string,string>替代，

Dictionary<string, string> dic = new Dictionary<string, string>();
dic.Add("1", "Monday");
dic.Add("2", "Tuesday");

ddl.DataSource = dic;
ddl.DataTextField = "Value";
ddl.DataValueField = "Key";
ddl.DataBind();
