我如何添加项目，下拉列表

foreach (XXXX in YYYY)
            {
                DropDownList1.Items.Add(new ListItem("Adana", "5577"));

使用Json.Net

var response =  JsonConvert.DeserializeObject<Response>(json);
foreach(var item in response.datas)
{
    DropDownList1.Items.Add(new ListItem(item.Value, item.Key));
}

public class Response
{
    public bool state;
    public Dictionary<string, string> datas;
}

您必须首先将 json 反序列化为字典 http://www.codeproject.com/Tips/79435/Deserialize-JSON-with-C ，然后在字典中迭代以填充您的 DropDownList1

这应该有助于：

反序列化 json 数据，然后对其进行迭代。
