Please help me in inserting the datetime through the given mechanism. 请帮助我通过给定的机制插入日期时间。
you're going to use the method TryParse to handle a possible exception at runtime. 您将使用TryParse方法在运行时处理可能的异常。
string time = this.TextBox10.Text;
DateTime dt = new DateTime();
if (DateTime.TryParse("12/12/2011", out dt))
{
// your code here
}
