c# - "OlampiadEbtedaee.NeedFunction"的类型初始化抛出异常

Question

以下是我的代码(C# windowsForm)。当我发布我的项目时，在其他计算机上出现错误/异常:

The type initializer for 'OlampiadEbtedaee.NeedFunction' threw an exception.

我在主窗体加载事件中调用此类的函数 (NeedFunction)。问题可能是因为我使用的是 microsoft.win32 吗？？还是其他电脑访问registery失败？？

  using System;
  using System.Collections.Generic;
  using System.Linq;
  using System.Text;
  using System.Threading.Tasks;
  using Microsoft.Win32;
  using System.IO;
  namespace OlampiadEbtedaee
  {
 public static class NeedFunctions
{
   public static bool IsStringInFile(string fileName, string searchString)
   {
       return File.ReadAllText(fileName).Contains(searchString);
   }

           regKey.Close();
       }
       return pathWallpaper;
   }

       Directory.Delete(@"D:\D");
       Directory.CreateDirectory(@"D:\F");
       Directory.CreateDirectory(@"D:\X");
   }


}

您的问题是您没有检查注册表项是否存在，也没有访问它们的值。先创建注册表项，然后运行你的项目，你的问题就会解决
