＆QUOT;不含适合的切入点＆QUOT一个静态的'主'的方法; [英] "does not contain a static 'main' method suitable for an entry point"

问题描述

我不明白什么是我的错我的低于code。

I can't figure what's my wrong with my code below.

当我尝试编译我得到的消息：

When I try to compile I get the message:

不包含适合的切入点静态'主'的方法。

does not contain a static 'main' method suitable for an entry point.

这是我的code：

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 RandomNumberGenerator
{

public partial class Form1 : Form
{
    private const int rangeNumberMin = 1;
    private const int rangeNumberMax = 3;
    private int randomNumber;

public Form1()
{            
        randomNumber = GenerateNumber(rangeNumberMin, rangeNumberMax);
}

private int GenerateNumber(int min,int max)
    {
        Random random = new Random();
        return random.Next(min, max);
    }

private void Display(object sender, EventArgs e)
    {                       
        switch (randomNumber)
        {
            case 1:
            MessageBox.Show("A");
            break;
            case 2:
            MessageBox.Show("B");
            break;
            case 3:
            MessageBox.Show("C");
            break;
        }

    }           
}
}

有人可以告诉我在哪里，我已经错了。

Can someone please tell me where I've gone wrong.

推荐答案

每一个C＃程序需要一个切入点。默认情况下，一个新的C＃Windows窗体项目包括一个中的Program.cs文件程序类：

Every C# program needs an entry point. By default, a new c# Windows Forms project includes a Program class in a Program.cs file:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace StackOverflow6
{
    static class Program
    {
        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        [STAThread]
        static void Main()
        {
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            Application.Run(new Form1());
        }
    }
}

你可能缺少此或删除它。

You are probably missing this or deleted it.
