问题描述

谁能说出下面给出的代码为什么不起作用?

I have to write the code on button click for addition of two nos.

Can anyone tell why the code given below is not working?

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace myproject
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            int number1;
            int number2;
            int answer;



number1 = 3;
number2 = 5;

answer = number1 + number2;

//MsgBox(answer);


        }
    }

推荐答案

该代码似乎还可以.要查看结果，您可以编写:

That code seems quite ok. To see the results you can write:

MessageBox.Show(answer.ToString(); //Shows a message box with the content "8"

如果这不是问题，则应向我们显示错误消息.

If this is not the problem, you should show us the error message.

添加文本框以显示结果..

然后，

Add a textbox to display the result..

then,

TextBox1.Text = answer.Tostring();
