如何在vb.net中将标签类型转换为日期类型

Dim dateString As String = "2022-01-01"
Dim format As String = "yyyy-MM-dd"
Dim provider As CultureInfo = CultureInfo.InvariantCulture
Dim dateValue As DateTime = DateTime.ParseExact(dateString, format, provider)

Dim dateString As String = "2022-01-01"
Dim format As String = "yyyy-MM-dd"
Dim provider As CultureInfo = CultureInfo.InvariantCulture
Dim dateValue As DateTime

If DateTime.TryParseExact(dateString, format, provider, DateTimeStyles.None, dateValue) Then
    ' 转换成功
    Console.WriteLine("转换成功，日期为：" & dateValue.ToString())
Else
    ' 转换失败
    Console.WriteLine("转换失败")
End If
