Question

我试图用参数调用一个动作结果，但它们都显示为null？

这是我的ActionLink：

@Html.ActionLink("Add", "APNewQuote", "APQuotes", new {OENum = Model.OENumber, QuoteNumber = Model.QuoteNumber, ClaimNumber = Model.ClaimNumber, MotorBodyRepairer = Model.MotorBodyRepairer, VehicleRegistration = Model.VehicleRegistration, VehicleMakeId = Model.VehicleMakeId, VehicleModelId = Model.VehicleModelId, VehicleRangeId = Model.VehicleRangeId}, new { @class = "btn btn-primary niceButton" })

在我的控制器中：

public ActionResult APNewQuote(string OENum, string QuoteNumber, string ClaimNumber, string MotorBodyRepairer, string VehicleRegistration, int? vehicleMakeId, int? vehicleModelId, int? vehicleRangeId)
{
 //Do things with the variables passed in

 APNewQuoteViewModel viewModel = new APNewQuoteViewModel
 {
  OENumber = OENumber,
  QuoteNumber = QuoteNumber,
  ClaimNumber = ClaimNumber,
  MotorBodyRepairer = MotorBodyRepairer,
  VehicleRegistration = VehicleRegistration,
  VehicleMakeId = vehicleMakeId,
  VehicleMakes = vehicleMakes,
  VehicleModelId = vehicleModelId,
  VehicleModels = vehicleModels,
  VehicleRanges = vehicleRanges,
  VehicleRangeId = vehicleRangeId,
  Date = Date
 };

 return View(viewModel);
}

上面的方法用于初始显示视图，如果所有输入参数都为空，则它很好，但是当我再次调用动作Result时，我需要使用这些参数，因此它们不能为空。

我可以运行我的项目，当我点击我的动作链接时，我只是为了一切恢复null，它确实会移动到正确的方法。

您可以尝试访问ike：Request.Params[0]

确保以下MVC Helper代码生成带有查询字符串的链接

@Html.ActionLink("Add", "APNewQuote", "APQuotes", new {OENum = Model.OENumber, 
     QuoteNumber = Model.QuoteNumber, ClaimNumber = Model.ClaimNumber, 
     MotorBodyRepairer = Model.MotorBodyRepairer, VehicleRegistration = 
     Model.VehicleRegistration, VehicleMakeId = Model.VehicleMakeId, 
     VehicleModelId = Model.VehicleModelId, VehicleRangeId = Model.VehicleRangeId}, 
    new { @class = "btn btn-primary niceButton" })

即

<a href="/APNewQuote/Add?OENum=val1&QuoteNumber=val2,etc">APQuotes</a>

然后，默认情况下，您的控制器方法应该能够为[HttpGet]提供服务。如果您只使用[HttpPost]修饰，请同时添加HttpGet动词。

[HttpGet]
[HttpPost]
public ActionResult APNewQuote(string OENum, string QuoteNumber, string ClaimNumber, string MotorBodyRepairer, string VehicleRegistration, int? vehicleMakeId, int? vehicleModelId, int? vehicleRangeId)
{

}

ActionLink参数不起作用？
