为什么这在 Visual Studio 2019 中运行而不是 2022？ c#中的方法

Question

尝试学习 c# 中的方法/函数，但这段代码由于某种原因无法运行，但它确实可以在 visual studio 2019 中运行。

编辑：添加了我在下面遇到的错误

static int ThrowDice(int slag)
{
    return ThrowDice(6, slag);
}

static int ThrowDice(int sidor, int slag)
{
    int resultat = 0;
    Random rnd = new Random();
    for (int i = 0; i < slag; i++)
    {
        int varjekast = rnd.Next(1, sidor + 1);
        Console.WriteLine($"kast{i+1} blir {varjekast}");
        resultat += varjekast;
    }

    return resultat;
}


Console.WriteLine("Ange tärningens antal sidor: ");
int sidor = int.Parse(Console.ReadLine());
Console.WriteLine("Ange tärningskast: ");
int kast = int.Parse(Console.ReadLine());
Console.WriteLine("Resultat: " + ThrowDice(sidor, kast));

Console.ReadLine();

我得到的错误：

Severity    Code    Description Project File    Line    Suppression State
Error   CS1501  No overload for method 'ThrowDice' takes 2 arguments
Severity    Code    Description Project File    Line    Suppression State

正如您的错误消息告诉您的那样，您不能对具有相同名称的本地函数进行 delcare：

Error   CS0128  A local variable or function named 'ThrowDice' is already defined in this scope

所以你需要给它们起不同的名字，或者像这样把它们放在 class 中

Console.WriteLine ("Ange tärningens antal sidor: ");
int sidor = int.Parse (Console.ReadLine ());
Console.WriteLine ("Ange tärningskast: ");
int kast = int.Parse (Console.ReadLine ());
Console.WriteLine ("Resultat: " + new Dice().ThrowDice (sidor, kast));

public class Dice
{
  public int ThrowDice (int slag)
  {
    return ThrowDice (6, slag);
  }

  public int ThrowDice (int sidor, int slag)
  {
    int resultat = 0;
    Random rnd = new Random ();
    for (int i = 0; i < slag; i++)
    {
      int varjekast = rnd.Next (1, sidor + 1);
      Console.WriteLine ($"kast{i + 1} blir {varjekast}");
      resultat += varjekast;
    }

    return resultat;
  }
}
