立即使用（）为国外

-1

我试图将不同的日期格式转换为适当的SQL DateTime格式，并且出现错误。立即使用（）为国外

我有一个客户端的机器，是建立与下列日期格式，“DD-MM-YYYY”（本地化是印度）

当内VB.Net NOW（）使用它分析的月份和日子向后。我试过下面的代码，但得到转换错误。

Dim Month As String = Nothing 
    Dim Year As String = Nothing 
    Dim Day As String = Nothing 
    Dim Hour As String = Nothing 
    Dim Minute As String = Nothing 
    Dim Second As String = Nothing 
    Dim strDate As String = Nothing 
    Dim Date_to_SQL_DateTime As Date 


    Month = DatePart(DateInterval.Month, Now()).ToString 
    Year = DatePart(DateInterval.Year, Now()) 
    Day = DatePart(DateInterval.Day, Now()) 
    Hour = DatePart(DateInterval.Hour, Now()) 
    Minute = DatePart(DateInterval.Minute, Now()) 
    Second = DatePart(DateInterval.Second, Now()) 

    strDate = Month & “/” & Day & “/” & Year & “ “ & Hour & “:” & Minute & “:” & Second 

    Date_to_SQL_DateTime = Date.ParseExact(strDate, "MM/dd/yyyy hh:mm:ss", CultureInfo.InvariantCulture)

strDate返回

1/24/2017 23:17

错误我收到是

String was not recognized as a valid Datetime

您可以使用GetDate（）来替代，还是仅将日期作为Date参数传递？ –

@AndrewMortimer嗯，这真的打开了另一罐蠕虫......并进入使用UTC时间与用户特定的偏移量。我宁愿将时间存储在数据库中，因为日期时间和特定于当前时间。这是一个很好的想法，我需要做的事情.. –

你可以显示你的插入语句吗？ –

下面尝试。需要确保参数的格式与ParseExact函数中指定的格式相同。

Dim Month As String = Nothing 
Dim Year As String = Nothing 
Dim Day As String = Nothing 
Dim Hour As String = Nothing 
Dim Minute As String = Nothing 
Dim Second As String = Nothing 
Dim strDate As String = Nothing 
Dim Date_to_SQL_DateTime As Date 

Month = DatePart(DateInterval.Month, Now()).ToString("00") 
Year = DatePart(DateInterval.Year, Now()).ToString("0000") 
Day = DatePart(DateInterval.Day, Now()).ToString("00") 
Hour = DatePart(DateInterval.Hour, Now()).ToString("00") 
Minute = DatePart(DateInterval.Minute, Now()).ToString("00") 
Second = DatePart(DateInterval.Second, Now()).ToString("00") 

strDate = Month & "/" & Day & "/" & Year & " " & Hour & ":" & Minute & ":" & Second 
Date_to_SQL_DateTime = DateTime.ParseExact(strDate, "MM/dd/yyyy hh:mm:ss", CultureInfo.InvariantCulture)
