错误地说“必须声明一个身体” [英] Error saying "must declare a body"

问题描述

我正在调试代码，我得到了1个错误。

它缺少一个main方法，所以我做了静态void（）;在代码的开头。

错误说ffbCS.Program.Main（）必须声明一个正文，因为它没有标记为abstract，extern或partial

以下是我的代码

-------------------------------------- --------------------------------------------

I was debugging a code and I got it to 1 error.
It was missing a main method, so I did static void Main(); in the beginning of the code.
The error says "ffbCS.Program.Main() must declare a body because it is not marked abstract, extern, or partial"
Below is my code

推荐答案

答案在于错误。 Main（）方法没有正文。

方法必须有一个正文，除非你在一个接口中声明了它，或者它被标记为abstract，extern或partial。



尝试更换

The answer lies in the error. The Main() method doesn't have a body.
A method must have a body unless you have declared this inside an interface or it is marked abstract, extern, or partial.

Try replacing

static void Main();

with

with

static void Main(){}

希望这会解决你的问题问题。

如果我误解了一些内容，请告诉我更多详情：）

Hopefully, this resolves your problem.
If I misunderstood something, please let me know with little more details :)

Main（）是程序的起点..和所有方法或引用应该在main（）内，即这应该是你的代码..

Main() is the starting point of program.. and all methods or references should come inside main() i.e this should be your code..

namespace ffbCS
{
    class Program
    {
        static void Main()
        {
               //All Methods and References comes here
        }
     }
}

这是你应该做的事情

This is what you should do

class Program
{
   public static void Main()
   {
          DirectInputWrapper inst = new DirectInputWrapper();
   }
}
