你最喜欢的是后绑定模型 比如说
public ActionResult myController(){
var model= new myModel();
return View(model);
}
[HttpPost]
public ActionResult myController(myModel model){
model.StaffId = 1;
return View(model);
}

您没有发布控制器代码。无论如何,试试这个例子
[HttpPost]
public ActionResult <Resultnamehere>(<YOUR MODEL CLASS HERE> model)
{
return View(Model);
}
[HttpPost]
公共行动结果(模型)
{
返回视图(模型);
}

为了获得更好的结果,请为编程语言添加一个标记在控制器的post方法中有返回视图()之前的部分可能会更好,但据我所见,这可能是因为在post方法中,不会重新填充ViewBag变量。您需要在每个返回视图之前设置它们。为了获得更好的结果,请添加编程语言的标记。最好在控制器的post方法中包含返回视图()之前的部分,但从我看到的情况来看,这可能是因为在post方法中,不会重新填充ViewBag变量。您需要在每次返回视图之前设置它们。我的控制器代码:[HttpPost][ValidateAntiForgeryToken]公共操作结果创建([Bind(Include=“StaffId,Tdate,Edate”)]TrainingRecord TrainingRecord{if(ModelState.IsValid){db.TrainingRecordDBSet.Add(TrainingRecord);db.SaveChanges();返回重定向到操作(“搜索”,“训练记录”,新建{id=trainingRecord.StaffId});}返回视图(trainingRecord);}我的控制器代码:[HttpPost][ValidateAntiForgeryToken]公共操作结果创建([Bind(Include=“StaffId,Tdate,Edate”)]trainingRecord训练记录){if(ModelState.IsValid){db.TrainingRecordDBSet.Add(trainingRecord);db.SaveChanges();返回重定向到操作(“搜索”,“TrainingRecords”,new{id=trainingRecord.StaffId});}返回视图(trainingRecord);}我的控制器代码:[HttpPost][ValidateAntiForgeryToken]公共操作结果创建([Bind(Include=“StaffId,Tdate,Edate”)]trainingRecord trainingRecord trainingRecord){if(ModelState.IsValid){db.TrainingRecordDBSet.Add(trainingRecord);db.SaveChanges();返回重定向到操作(“搜索”,“TrainingRecords”,new{id=trainingRecord.StaffId});}返回视图(trainingRecord);}我的控制器代码:[HttpPost][ValidateAntiForgeryToken]公共操作结果创建([Bind(Include=“StaffId,Tdate,Edate”)]TrainingRecord TrainingRecord{if(ModelState.IsValid){db.TrainingRecordDBSet.Add(TrainingRecord);db.SaveChanges();返回重定向到操作(“搜索”,“TrainingRecords”,new{id=TrainingRecord.StaffId});}返回视图(TrainingRecord);}
