namespace PROJ.Service {
   public static class ExceptionDatesUpdateService {
        public static ExceptionDatesUpdateService()
        {
        }

        public static bool IsServiceRunning() {
            return _updateThread != null && _updateThread.IsAlive;
        }
   }
}

当我尝试使用上面的静态类时，它说它不可访问。为什么？参考存在。

using PROJ.Service;
namespace PROJ.admin {
  public void ProcessRequest(HttpContext context) {
    bool ch = ExceptionDatesUpdateService.IsServiceRunning();
  }
}

感谢大家。问题被发现了。当我解决其他错误并编译它时。它消失了。我是 C# 新手，很抱歉这个愚蠢的问题。:)

Assuming you've added the appropriate project reference, one problem I see is that static type initializers cannot have access modifiers. Try this:

public static class ExceptionDatesUpdateService {
    static ExceptionDatesUpdateService()
    {
    }
}

Of course, if there's nothing inside the initializer, you can just remove it entirely.

Check if Target Framework is same in the project properties for both the projects.

This is often caused by different .NET framework versions being set in the project properties. For instance, one project may be .NET 3.5 and you're trying to reference a .NET 4.0 project.

It can also be caused by a similar x64 vs x86 mismatch.

Usually the reference itself will have a warning icon next to it.

namespace PROJ.admin 
{
    public static class NewClass

        {
            bool ch = ExceptionDatesUpdateService.IsServiceRunning();
        }
    }
}

试试这个工作
