vb net中怎么样将字符串类型转换成日期型

Answer 1

给你一个例子，里边包含了几种不同格式转换成标准的日期时间格式；
Public Class Form1

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Try
' 01/09/2001 00:00:00
Dim MyDateTime1 As DateTime = DateTime.Parse("Sep 2001")
' 05/09/2001 14:15:33
Dim MyDateTime2 As DateTime = DateTime.Parse("Wed 5 September 2001 14:15:33")
' 01/09/2005 00:00:00
Dim MyDateTime3 As DateTime = DateTime.Parse("5,9,01")
' 09/05/2001 14:15:33
Dim MyDateTime4 As DateTime = DateTime.Parse("5/9/2001 14:15:33")
' 当前系统日期 14:15:00
Dim MyDateTime5 As DateTime = DateTime.Parse("2:15 PM")
Dim MyInfo As String = MyDateTime1.ToString()
MyInfo += vbCrLf + MyDateTime2.ToString()
MyInfo += vbCrLf + MyDateTime3.ToString()
MyInfo += vbCrLf + MyDateTime4.ToString()
MyInfo += vbCrLf + MyDateTime5.ToString()
MessageBox.Show(MyInfo, "信息提示", _
MessageBoxButtons.OK, MessageBoxIcon.Information)
Catch ex As Exception
MessageBox.Show(ex.Message, "信息提示", _
MessageBoxButtons.OK, MessageBoxIcon.Information)
End Try

End Sub
End Class
