我想将DD/MM/YYYY
表格中存储的日期与当前日期进行比较。
我需要知道它是否早于或晚于DateTime.Now
...
有人有想法建议吗?
提前谢谢。

您可以使用DateTime.Compare
:
var result = DateTime.Compare(Convert.ToDateTime(TextBox1.Text), DateTime.Today);
string relationship;
if (result < 0)
relationship = "is earlier than";
else if (result == 0)
relationship = "is the same time as";
else
relationship = "is later than";
Console.WriteLine("{0} {1} {2}", date1, relationship, date2);
有关详细信息,请参阅MSDN上的documentation。

您可以使用以下代码将时间戳解析为DateTime对象,然后根据需要进行比较。
DateTime date;
DateTime.TryParseExact("12/03/2009", "dd/MM/yyyy", null, DateTimeStyles.None, out date);

这可以使用DateTime.Compare方法完成:
date1 = Convert.ToDateTime(TextBox1.Text)
date2 = DateTime.Today
var result = DateTime.Compare(date1, date2)
string relationship
if (result < 0)
relationship = "is earlier than";
else if (result == 0)
relationship = "is the same time as";
else
relationship = "is later than";
Console.WriteLine("{0} {1} {2}", date1, relationship, date2);
