Question

我有以下代码：

protected void Button1_Click(object sender, EventArgs e)
{
    count1++;
}

我希望每次有人点击按钮时计数器count1都会增加。然而，到目前为止它只计算第一次点击，而不是任何其他跟随，所以它总是停留在1.外面，我已经声明它并将其初始值设置为0.问题出在哪里？（我使用visual studio 2015）

编辑：这是整个代码：

 using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

public partial class Statistics : System.Web.UI.Page
{
    int count1 = 0, count2 = 0;
    string minima = "Καλησπέρα";
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!Page.IsPostBack)
        {
            TextBox1.Text = minima;
            Label1.Text = "Αυτή την στιγμή χρησιμοποιούν τον ιστότοπο " + Convert.ToString(Application["UserCount"]) + " χρήστες";

        }

    }

    protected void Button1_Click(object sender, EventArgs e)
    {
        TextBox2.Text = TextBox1.Text;
        count1++;
        Label2.Text = "Κλικ από προηγούμενους χρήστες: " + Convert.ToString(count1);
        Label3.Text = "Τρέχοντα κλικ: " + Convert.ToString(count1 + count2);
    }
}

（是的，我知道count2在任何时候都没有改变它的值，代码仍在进行中，因为它存在于另一个原因所以让我们暂时忽略它）

您的计数器正在重置每个回发试试这个

    String string = "{\"success\":1,\"data\":{\"html\":\"<div class=\\\"inner\\\">\\n      <span class=\\\"title js-title-eligible\\\">Upgrade available<\\/span>\\n    <span class=\\\"title js-title-warning\\\"><strong>WARNING :<\\/strong> You don\\u2019t own a <span class=\\\"js-from-ship\\\"><\\/span><\\/span>\\n        <p class=\\\"explain js-title-eligible\\\">Buy this upgrade and it will be applicable to your <span class=\\\"js-from-ship\\\"><\\/span> from the My Hangar section.<\\/p>\\n    <p class=\\\"explain js-title-warning\\\">You can buy this upgrade but it will only be applicable on a <span class=\\\"js-from-ship\\\"><\\/span>.<\\/p>\\n\\n    <div class=\\\"price\\\"><strong class=\\\"final-price\\\">\\u20ac5<span class='super'>.41 <span class='currency'>EUR<\\/span><\\/span><\\/strong><div class=\\\"taxes js-taxes\\\">\\n  <div class=\\\"taxes-details trans-02s\\\">\\n    <div class=\\\"arrow\\\"><\\/div>\\n    Tax Included: <br \\/>\\n    <ul>\\n        <li>VAT 19%<\\/li>\\n        <\\/ul>\\n  <\\/div>\\n<\\/div><\\/div>\\n\\n\\n    <div>\\n      <a href=\\\"\\/pledge\\/Upgrades\\/Mustang-Alpha-To-Aurora-LN-Upgrade\\\" class=\\\"add-to-cart holosmallbtn trans-03s js-add-to-cart-ship ty-js-add-to-cart\\\" data-sku=\"1086\\\">\\n        <span class=\\\"holosmallbtn-top abs-overlay trans-02s\\\">BUY NOW<\\/span>\\n        <span class=\\\"holosmallbtn-bottom abs-overlay trans-02s\\\"><\\/span>\\n      <\\/a>\\n      <a href=\\\"\\/pledge\\/Upgrades\\/Mustang-Alpha-To-Aurora-LN-Upgrade\\\" class=\\\"more-details\\\">View more details<\\/a>\\n    <\\/div>\\n    \\n    <p class=\\\"explain info\\\">\\n      Upgrades that you buy can be found in your <a href=\\\"\\/account\\/pledges\\\">Hangar section<\\/a>.<br \\/>\\n      Click \\\"Apply Upgrade\\\" inside the Upgrade Pledge to pick where you want to apply it.\\n    <\\/p>\\n  <\\/div>\\n\\n\\n\\n\"},\"code\":\"OK\",\"msg\":\"OK\"}";

    String pattern="(?<=data-sku=)([\\\\]*\")(\\d+)";

    Pattern p = Pattern.compile(pattern);

    Matcher matcher = p.matcher(string);

     while (matcher.find()) {
            System.out.print("Start index: " + matcher.start());
            System.out.println(" End index: " + matcher.end() + " ");
            System.out.println("number="+matcher.group(2));
        }

C＃ - 单击多次时按钮计数器不会增加
