Question

我正在创建一个.txt文件输出“ data.txt”。在文件内部，我想在用户每次选择特定按钮时设置一个增量值。例如，如果用户单击“投票约翰”。第一次，“约翰，1岁” 第二次，“约翰2岁”

但是，我的价值本身并没有增加。请指教。谢谢。

@{
    var result = "";
    int countJohn = 1;

    if (IsPost)
    {
        if (Request["submit"] == "Vote Harry")
        {

            //var harry = Request["Harry"];

            int countHarry = 1;

            var userData = "Harry" + "," + countHarry + Environment.NewLine;

            var dataFile = Server.MapPath(@"~/App_Data/data.txt");

            File.AppendAllText(@dataFile, userData);

           // countHarry += countHarry;  does not increases the count inside  .txt at all

            result = "Information saved.";
        }

        else if (Request["submit"] == "Vote John")
        {

            //var john = Request["John"];

            var userData = "John" + "," + (Int32.Parse("1")) + Environment.NewLine;

            var dataFile = Server.MapPath(@"~/App_Data/data.txt");

            File.AppendAllText(@dataFile, userData);

            result = "Information saved.";

            countJohn += 1;
        }
    }
 }
