Question

这是我应用程序的主要布局

<!DOCTYPE html>

我在用户登录时获得侧边栏，所有链接都在边栏中工作，但

除外

@Html.ActionLink("myconn", "Action", "Controller")

当我点击名为SuperOffice的链接时，浏览器链接更改为http://localhost:14834/Connection 但我得到错误：在视觉工作室说

An unhandled exception of type 'System.StackOverflowException' occurred in System.Core.dll

这是我的控制器代码

[Authorize]
public class Controller : Controller
{
    private readonly IConnectionRepository _connectionRepository;

    public ConnectionController(IConnectionRepository connectionRepository)
    {
        _connectionRepository = connectionRepository;
    }
}

当我在Connection控制器的Index方法中放置断点，并单击SuperOffice链接时，我甚至没有使用该方法。知道发生了什么吗？我觉得很奇怪，所有的链接都在工作，我被转发到控制器，除了那个之外，所有的东西都很完美。

Answer 1

    var hasSuperOfficeConnection = _connectionRepository.CheckIfSuperOfficeIsConnected(userId);
    var model = new Index
    {
        IsSuperOfficeConnected = hasSuperOfficeConnection
    };

我认为这里有一个无限循环如果你能提供更多代码（即IsSuperOficeConnected）我们可以帮助你更多

public class ConnectionRepository:IConnectionRepository
{
    private readonly DatePickerDbContext _db;
    //private readonly ISuperOfficeRepository _superOfficeRepository;

    public ConnectionRepository(DatePickerDbContext db)//, ISuperOfficeRepository superOfficeRepository
    {
        _db = db;
      //  _superOfficeRepository = superOfficeRepository;
    }
     public int GetConnectionId(string connectionName)
     {
        var connection = _db.Connections.Single(c => c.Name == connectionName);
        return connection.Id;
      }

     public bool CheckIfSuperOfficeIsConnected(string userId)
     {
        var connectionId = GetConnectionId("SuperOffice");
        var result = _db.UserConnections.Where(uc => uc.UserId == userId && uc.ConnectionId == connectionId);
        return result.Any();
     }
 }

Answer 2

你可能在某个地方有[Authorize]属性，它给你stackoverflow。
