在 Visual Basic 中将表示为字符串的日期转换为日期

Question

我正在使用SSIS，我需要转换日期。 如何在 VB.NET 中将字符串格式的日期（例如 1980 年 9 月 14 日）转换为相同但日期格式？

我希望将日期时间格式插入 SQL 数据库。

在VB.NET:

' Assume the current culture is en-US. 
' The date is Feburary 16, 1992, 12 hours, 15 minutes and 12 seconds.
Dim myDateTimeValue As String = "2/16/1992 12:15:12"  
Dim myDateTime As DateTime = DateTime.Parse(myDateTimeValue)

' Reverse month and day to conform to a different culture.
' The date is Feburary 16, 1992, 12 hours, 15 minutes and 12 seconds.
Dim cultureGB = New CultureInfo("en-GB", True)
Dim myDateTimeValue As String = "16/2/1992 12:15:12"  
Dim myDateTime As DateTime = DateTime.Parse(myDateTimeValue, cultureGB)

' Dsiplay the date in DD/MM/YYYY format
Debug.Print Format(myDateTime ,"dd/MM/yyyy")

在VB6:

dim dt as date
dim s as string
s="10/09/2009"
dt = cdate(s)
