VB.NET：如何將字符串轉換爲日期？

Question

我已經通過字符串文本文件即將通過的SSIS包形式：

"20090910" (string) 

和它需要

2010-09-01 00:00:00 (Date) 

有什麼建議？

嘗試從MSDN DateTime.ParseExact()

實例與您的數據：

Dim dateString, format As String 
Dim result As Date 
Dim provider As Globalization.CultureInfo = Globalization.CultureInfo.InvariantCulture 

' Parse date and time with custom specifier. 
dateString = "20090910" 
format = "yyyyMMdd"   
Try 
    result = Date.ParseExact(dateString, format, provider) 
    Console.WriteLine("{0} converts to {1}.", dateString, result.ToString()) 
    Console.ReadLine() 
Catch e As FormatException 
    Console.WriteLine("{0} is not in the correct format.", dateString) 
End Try
