Main（）方法必须有一个返回类型错误;第一天搞乱与C＃＃

本文介绍了Main（）方法必须有一个返回类型错误;第一天搞乱与C＃＃的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 我正在学习如何使用C＃，并且在我的班级作业的一部分中遇到过这个错误。不幸的是，我现在的代码是文盲，所以请耐心等待我。基于下面的代码，我知道我正在编译错误的东西，但我不明白我做错了什么并且继续得到CS1520方法必须有一个返回类型错误并且无法找出原因。 编辑：向静态void添加void Main（）产生CS0017错误定义了多个入口点。再一次，我不明白这意味着什么，或者我应该解决什么。 我尝试过： I'm just learning how to use C# and have been faced with this error as part of an assignment for my class. Unfortunately, I'm code illiterate at the moment, so please be patient with me. Based on the code below, I know that I'm compiling something wrong, but I don't understand what I'm doing wrong and keep getting a CS1520 "Method must have a return type" error and can't figure out why. Adding void to static void Main() produces a CS0017 error of "More than one entry point defined". Yet again, I don't understand what this means, or what I should fix.What I have tried:using System;using System.Linq;class Program{ static Main() { int number1, number2, number3; Console.Write("Enter an integer score"); number1 = Convert.ToInt32(Console.ReadLine()); Console.Write("Enter an integer score"); number2 = Convert.ToInt32(Console.ReadLine()); Console.Write("Enter an integer score"); number3 = Convert.ToInt32(Console.ReadLine()); int result = (number1 + number2 + number3) % 3; Console.WriteLine("The average of {0}, {1}, {2} is: {3}", number1, number2, number3, result); }} 推荐答案 Quote： int result = （number1 + number2 + number3）％3; int result = (number1 + number2 + number3) % 3;这不计算三个整数的平均值。你应该写： That's not compute the average of the three integers. You should write instead:double avg = (number1 + number2 + number3) / 3.0; 这篇关于Main（）方法必须有一个返回类型错误;第一天搞乱与C＃＃的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
