從數據庫作爲貨幣

Question

返回字符串我有

SELECT  SUM(Price) AS Sales 
FROM   BarOrder 
WHERE  (OrderDate <= @OrderDateEnds) AND (OrderDate >= @OrderDateStarts) 

我的價格區域被設置爲浮動，這樣能夠存儲美分以下查詢。這部分工作正常。現在我想用以下

lblTodayAmount.Text = Cstr(BarOrderTableAdapter.TodaysSalesAmount(CDate(strEndDay), CDate(strBeginDay)))("C") 

我得到以下檢索貨幣格式的信息：

Conversion from string "C" to type 'Integer' is not valid. 

，如果我做到以下幾點：

BarOrderTableAdapter.TodaysSalesAmount(CDate(strEndDay), CDate(strBeginDay))("C") 

然後我得到：

No default member found for type 'Double'. 

Answer 1

使用ToString，不CStr

lblTodayAmount.Text = BarOrderTableAdapter.TodaysSalesAmount(CDate(strEndDay), CDate(strBeginDay)).ToString("C")
