我是MVC的新手，並花了幾個小時試圖找到解決這個問題。我正在嘗試爲一些出租物業設置發票系統。財產管理者提供一個包含當前水讀數的excel文件。我必須扣除上個月的水量數據以瞭解每月的使用情況。我所做的觀點是這樣做的，並同時顯示所有單位。我遇到的問題是將上傳的文件和模型數據（上個月的讀數）一起傳遞給控制器。該文件顯示，但沒有其他數據。MVC更新視圖與上傳文件
在視圖中我有兩個提交按鈕。一個用於上傳要整合到模型數據中的文件，另一個用於基於之前和當前（上載的）數據創建新記錄。以下是相關的模型，視圖和控制器。
最終，賬單管理員會看到上個月的數據，上傳新數據，檢查並驗證沒有錯誤，然後提交新發票的數據。
如果有更好的方法來完成那麼我在這裏嘗試請讓我知道。這看起來好像用所有的linq查詢重新創建模型數據會更容易。在此先感謝您的幫助！
型號：
public partial class UtilityData
{
public DateTime bEntryDate { get; set; }
public string bPrevDate { get; set; }
public int bID { get; set; }
//public int residenceCount { get; set; }
public IEnumerable<UtilEntry> utilData { get; set; }
public HttpPostedFileBase UploadFile { get; set; }
}
public partial class UtilEntry
{
public int rID { get; set; }
public long? WaterReading { get; set; }
public int ResNumber { get; set; }
public long? prevWaterReading { get; set; }
public decimal wDifference { get; set; }
public int GrnUpper { get; set; }
public int GrnLower { get; set; }
public int YelUpper { get; set; }
public int YelLower { get; set; }
}

您好，我認爲這將是最好不要使用Excel的全部，你能不能創造一個經理可以將數據輸入網站上的形式？ – GreatJobBob
