是否可以將Linq格式化爲價格

我正在使用C＃MVC。我有一個使用Linq導出CSV Excel文件的類，我想將一列的格式設置爲一個價格，而不是一個小數，可能有無限多的0。是否可以將Linq格式化爲價格

控制器：

public ActionResult Summary() 
     { 
      _logger.Debug("Request made for File."); 

      var currentYearSetup = _db.GetYearSetupForMostRecentOrCurrentReportingPeriod(); 
      var types = _db.GetAnimalTypes().ToArray(); 
      var rows = _db.GetSummaryRows(); 
      var file = _sm.CreateSummaryFile(rows); 
      var filename = String.Format("Summary_{0}.csv", DateTime.Now.ToString("yyyy_MM_dd__HH_mm")); 
      _logger.DebugFormat("Serving {0}", filename); 
      return File(file, System.Net.Mime.MediaTypeNames.Application.Octet, filename); 
     }

IRepository：

IEnumerable<SummaryRow> GetSummaryRows();

庫：

public IEnumerable<SummaryRow> GetSummaryRows() 
     { 
      var thing = _db.YearSetups.Select(i => new 
      { 
       Year = i.Name, 
       Transfer = _db.BatchPaymentSplits 
        .Where(bps => bps.YearSetupId == i.YearSetupId) 
        .Where(bps => bps.CustomerIdEntered != null) 
        .Where(bps => _db.BatchPayments 
         .Where(bp => _db.Batches.Where(b => b.BatchTypeId.Equals("T")) 
               .Select(b => b.BatchId) 
               .Contains(bp.BatchId) 
         ) 
         .Select(bp => bp.BatchPaymentId).Contains(bps.BatchPaymentId) 
        ) 

        .Sum(bps => (decimal?)bps.Amount) ?? 0, 
      }); 

      return _db.YearSetups.Where(y => _db.BatchPaymentSplits.Select(bps => bps.YearSetupId).Contains(y.YearSetupId)) 
      .Select(i => new 
      { 
       Year = i.Name, 
       Deposit = _db.BatchPaymentSplits 
        .Where(bps => bps.YearSetupId == i.YearSetupId) 
        .Where(bps => bps.CustomerIdEntered != null) 
        .Where(bps => _db.BatchPayments 
         .Where(bp => _db.Batches.Where(b => b.BatchTypeId.Equals("C") || b.BatchTypeId.Equals("E") || b.BatchTypeId.Equals("M")) 
               .Select(b => b.BatchId) 
               .Contains(bp.BatchId) 
         ) 
         .Select(bp => bp.BatchPaymentId).Contains(bps.BatchPaymentId) 
        ) 
        .Sum(bps => (decimal?)bps.Amount) ?? 0, 
       Transfer = _db.BatchPaymentSplits 
        .Where(bps => bps.YearSetupId == i.YearSetupId) 
        .Where(bps => bps.CustomerIdEntered != null)

               .Select(b => b.BatchId) 
               .Contains(bp.BatchId) 
         ) 
         .Select(bp => bp.BatchPaymentId).Contains(bps.BatchPaymentId) 
        ) 

        .Sum(bps => (decimal?)bps.Amount) ?? 0, 
       NSF = _db.BatchPaymentSplits

               .Contains(bp.BatchId) 
         ) 
         .Select(bp => bp.BatchPaymentId).Contains(bps.BatchPaymentId) 
        ) 

        .Sum(bps => (decimal?)bps.Amount) ?? 0, 
       BankCorrection = _db.BatchPaymentSplits 
        .Where(bps => bps.YearSetupId == i.YearSetupId) 
        .Where(bps => bps.CustomerIdEntered != null) 
        .Where(bps => _db.BatchPayments

         )

你如何導出爲CSV？標準方式是使用[標準貨幣格式代碼]（https://msdn.microsoft.com/en-us/library/dwhawy9k（v = vs.110）.aspx＃Anchor_1）將字段輸出爲字符串。。但是，如果不知道上下文，則不清楚是在查詢還是其他地方執行該操作。 –

我添加了一些代碼。我使用視圖中的鏈接調用控制器。 – BlowFish

這是一個有點很難說你的任何結構，沒有你發帖任何代碼。但是，以下展示瞭如何變換int爲貨幣字符串：

var intArray = new[] {3,5,6,7}; 
var currencyArray = intArray.Select(x => x.ToString("C"));

它給我：

kr. 3,00 
kr. 5,00 
kr. 6,00 
kr. 7,00
