namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
double firstNumber, seondNumber;
string userName;
Console.WriteLine("键入你的名字");
userName = Console.ReadLine();
Console.WriteLine("输入第一个字");
firstNumber = Convert.ToDouble(Console.ReadLine());
Console.WriteLine("键入第二个子");
seondNumber = Convert.ToDouble(Console.ReadLine());
Console.WriteLine("{0}{2}{3}", firstNumber, seondNumber, firstNumber + seondNumber);
Console.WriteLine("{0}{2}{3}", firstNumber, seondNumber, firstNumber - seondNumber);
Console.WriteLine("{0}{2}{3}", firstNumber, seondNumber, firstNumber * seondNumber);
Console.WriteLine("{0}{2}{3}", firstNumber, seondNumber, firstNumber

我帮你改正了
static void Main(string[] args)
{
double firstNumber, seondNumber;
string userName;
Console.WriteLine("键入你的名字");
userName = Console.ReadLine();
Console.WriteLine("输入第一个字");
firstNumber = Convert.ToDouble(Console.ReadLine());
Console.WriteLine("键入第二个子");
seondNumber = Convert.ToDouble(Console.ReadLine());
Console.WriteLine("{0}{1}{2}", firstNumber, seondNumber, firstNumber + seondNumber);
Console.WriteLine("{0}{1}{2}", firstNumber, seondNumber, firstNumber - seondNumber);
Console.WriteLine("{0}{1}{2}", firstNumber, seondNumber, firstNumber * seondNumber);
Console.WriteLine("{0}{1}{2}", firstNumber, seondNumber, firstNumber / seondNumber);
Console.WriteLine("{0}{1}的余数是{
