使用TempData是理想的Post-Redirect-Get模式。

您的文章操作：

[HttpPost] 
public ActionResult Create(string txthospitalname, int city) 
{ 
    var hospitals = new Hospital() 
    { 
     Name = txthospitalname, 
     FKCityID = city, 
     CreatedAt = DateTime.Now, 
     CreatedBy = 1, 
    }; 
    _db.Hospitals.Add(hospitals); 
    _db.SaveChanges(); 
    TempData["Success"] = true; 
    return RedirectToAction("Create"); 
} 

的GET操作：

[HttpGet] 
public ActionResult Create() 
{ 
    ViewBag.Success = TempData["Success"] as bool; 
    return View(); 
} 

您的看法：

@if (ViewBag.Success != null && ViewBag.Success) 
{ 
    <h2> Your Success Message Here</h2> 
} 

@using (Html.BeginForm("Create", "Hospital", FormMethod.Post, 
    new {enctype = "multipart/form-data", id = "hospitalform"})) 
{ 
    //Text Fields 
}
