无过载需要“0”参数 [c#]
我在 Start(); 处收到“没有重载需要 0 参数”的错误；我的主要方法中的一行。我不知道如何解决它，我四处寻找但找不到任何东西。
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace ConsoleApplication1
{
class Program
{
public static void main(string[] args)
{
Start();
}
public static string Start(string move)
{
Console.Write("");
string gameType = Console.ReadLine();
if (gameType == "s")
{
Console.Write("");
begin:
Console.Write("\nEnter your move: ");
move = Console.ReadLine();
switch (move)
{
case "r":
Console.Write("s");
Console.ReadLine();
break;
case "s":
Console.Write("");
Console.ReadLine();
break;
case "f":
Console.Write("");
Console.ReadLine();
break;
default:
Console.Write("\nInvalid move, try again\n\n");
goto begin;
}
Console.ReadLine();
return move;
}
else
{
return move;
}
}
static string Genius(string genius, string move)
{
Console.Write(move);
return genius;
}
}
}
I am getting an error of "No overload takes 0 args" at the Start(); line in my main method. I do not know how to fix it, and I've searched around and couldn't find anything.
using System;
using System.Collections.Generic;
using System.Linq;

public static string Start(string move)
{

对 Start 的方法调用应该是
Edit: 正如其他人指出的那样：将任何内容传递给 Start() 是没有意义的。传入的移动值将被忽略并替换为从控制台读取的值。因此，我建议简单地从 Start() 方法签名中删除参数，以便它只读取
The method call to Start should should be
Edit: as others have pointed out: there is no point in passing anything to Start(). The move value passed in is ignored and replaced by whatever is read from the console. Therefore I suggest simply removing the argument from the Start() method signature so it just reads
由于您正在从控制台读取移动，因此从 Start 的参数定义中删除
string move并将其作为局部变量移动到内部，应该没问题：顺便说一句，您的 main 应该be Main - 在 c# 中，main 应该大写 M！
我建议您阅读一些 C# 基础知识。
Since you are reading the move from the console, remove the
string movefrom the parameter definition of Start and move it inside as a local variable and it should be fine:And btw, your main should be Main - in c# the main should have a capital M!
I recommend you read some basics of C#.
提示：这是您的方法调用：
这是方法的签名：
它们之间不匹配...
Hint: this is your method call:
and this is the method's signature:
There is a mismatch between them...
你的 Start(arg) 应该是这样的：
Your Start(arg) should be like:
start 方法需要一个字符串作为参数：
示例：
开始（“r”）；
开始（“s”）；
开始（“f”）；
The start method expects a string as a parameter:
Examples:
Start("r");
Start("s");
Start("f");
您应该在调用 Start() 时传递一个参数（如 Anders 建议的那样），或者应该从 Start() 中删除该参数并将其声明为局部变量：
You should either pass an argument when Start() is called (as Anders suggested) or you should remove the argument from Start() and declare it as a local variable instead:
