參數無效的ActionLink？

我想用參數調用一個行爲結果，但它們都顯示爲null？參數無效的ActionLink？

這是我的ActionLink的：

@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" })

而在我的控制器：

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); 
}

上述方法用於initialy顯示視圖，以便它的細如果所有的輸入參數是空的，但當我再次調用動作結果時，我需要使用這些參數，以便它們不能爲空。

我可以運行我的項目，當我點擊我的動作鏈接時，我只是將所有內容都復位爲null，它確實移動到正確的方法。

您是否確認模型已傳遞到您的視圖。 –

@ Pomster ..你使用MVC 3嗎？我也面臨類似的問題 –

@AvinashKothamasu我正在使用MVC 4 – Pomster

你能嘗試訪問IKE在此：Request.Params[0]

我不確定你想要展示什麼？ – Pomster

@ Pomster ..我只是想讓你檢查你的模型值是否達到控制器？ –

確保下面的MVC助手代碼生成與查詢字符串的鏈接

@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>

那麼你的控制器方法應該默認情況下可以爲[HttpGet]提供服務。如果您僅使用[HttpPost]修飾，請添加HttpGet動詞。

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

}
