asp.net timespan

我使用時間跨度函數計算出天數，然後將此值添加到文本框並保存到數據庫。asp.net timespan

我最近添加了一個半天的單選按鈕，所以如果選中它，它將增加0.5天的假期而不是1天。這似乎在保存前顯示在文本框中時正常工作。但是，實際保存並更新數據庫時，顯示值爲1而不是0.5，如文本框中所示。

該字段在數據庫中的字段類型最初設置爲'int'，但當我添加了半天它不會保存，因爲它試圖保存一個小數，我已經將此字段類型更改爲'decimal'因爲它認爲這會更合適..我不確定這是否正確或應該是不同的東西？

我似乎無法弄清楚爲什麼它不保存在文本框中指定的值...任何建議

Private Sub btnHNoDays_Click(sender As Object, e As System.EventArgs) Handles btnHNoDays.Click 

    'declare dates 
    Dim dtStart As Date = txtHStart_Date.Text 
    Dim dtEnd As Date = txtHEnd_Date.Text 

    'timespan function used to minus one date to another and produce a value 
    Dim ts As TimeSpan = (dtEnd - dtStart) 

    If RadioButton1.Checked Then 

     ts = (dtEnd - dtStart) - TimeSpan.FromDays(0.5) 
    Else 
     ts = (dtEnd - dtStart) 
    End If 

    ' the value is set to to textbox. 
    txtNoofDays.Text = ts.TotalDays() 

    ' the today days value 
    Console.WriteLine(ts.TotalDays) 
End Sub

    'collect data
