错误 1 非静态的字段、方法或属性“sanjiaoxing.Program.qwx(string)”要求对象引用


我的代码
namespace sssssss
{
    class Program
    {
        int s;
     
          string qwx(string w)
        {
            if (int.TryParse(w, out s))
            {
                return "right";
            }
            else
            {
                Console.ForegroundColor = ConsoleColor.Blue;
                Console.Write("输入数据“{0}”有误，：", w);
                Console.ForegroundColor = ConsoleColor.White;
                return "wrong";
            }
        }

        static void Main(string[] args)
        {
           
            while (true)
            {
                int a, b, c;
                string a1, b1, c1,a2,b2,b3;
                Console.Write("\n");
                Console.ForegroundColor = ConsoleColor.White;
                while (true)
                {
                    Console.WriteLine("请输入第1数：");
                    a1 = Console.ReadLine();
                    a2 =qwx(a1);
                    if (a2 == "right")
                    {
                        break;
                    }
                    else
                    {
                        continue;
                    }           
                }
            }
        }

错误 1 非静态的字段、方法或属性“sanjiaoxing.Program.qwx(string)”要求对象引用

好像你的程序里面没有sanjiaoxing命名空间啊，你的把它加上！！--using sanjiaoxing；

不是这样的！关命名空间什么事情。那个都可以换的！

已经解决 楼主看看 基础不扎实啊

using System;
using System.Collections.Generic;
using System.Text;

namespace sssssss
{
    class Program
    {
        //修改为静态变量
        static int s;
        // 修改为静态方法
        static  string qwx(string w)
        {
            if (int.TryParse(w, out s))
            {
                return "right";
            }
            else
            {
                Console.ForegroundColor = ConsoleColor.Blue;
                Console.Write("输入数据“{0}”有误，：", w);
                Console.ForegroundColor = ConsoleColor.White;
                return "wrong";
            }
        }

        static void Main(string[] args)
        {

            while (true)
            {
                int a, b, c;
                string a1, b1, c1, a2, b2, b3;
                Console.Write("\n");
                Console.ForegroundColor = ConsoleColor.White;
                while (true)
                {
                    Console.WriteLine("请输入第1数：");
                    a1 = Console.ReadLine();
                    a2 = qwx(a1);
                    if (a2 == "right")
                    {
                        break;
                    }
                    else
                    {
                        continue;
                    }
                }
            }
        }
    }
}
