c# - 如何在 C# 中调试 "Unable to create a constant value of type ' System.Object'"？

Question

这是 Controller

public ActionResult login(login ob)
{
    bool mm = db.regs.Any(model => model.username == ob.username && model.password.Equals(ob.password));
    if (mm)
    {
        return RedirectToAction("welcome");
    }
    else
    {
        @ViewBag.err = "Invaid";
    }
    return View();
}

Controller 中的错误是

Unable to create a constant value of type 'System.Object'. Only primitive types or enumeration types are supported in this context.

Answer 1

使用==代替Equals

model.password == ob.password
