需要返回JSon数据集。

ASPX: $.ajax({ type: "POST", contentType: "application/json;utf-8", data: "{strclassid:'" + strclassid + "'}", url: "/AutoService.asmx/Show", success: function (msg) { var myObject = eval('(' + msg.d + ')'); for (var i = 0; i < myObject.length; i++) {     $("#selectabc").append(("<option value='" + myObject[i].Id + "'>" + myObject[i].Names + "</option>"));     }

Cs文件中可用

JavaScriptSerializer js = new JavaScriptSerializer(); return js.Serialize(USERS)

序列化
直接生成JSON文件更方便：

  StringBuilder sbGoodsName = new StringBuilder();       sbGoodsName.Append("[{\"GoodsName\":\"请选择\",\"GoodsID\":\"-1\"}");       DbDataReader dr = db.ExecuteReader(cmd);       while (dr.Read())        {            sbGoodsName.Append(",{");            sbGoodsName.Append("\"GoodsName\":" + "\"" + dr["names"].ToString() + "\",");            sbGoodsName.Append("\"GoodsID\":" + "\"" + dr["id"].ToString() + "\"");            sbGoodsName.Append("}");        }        dr.Close();        sbGoodsName.Append("]");        return sbGoodsName.ToString();
