日期检查在asp.net [英] date check in asp.net

问题描述

大家好

我需要检查一下出生日期是否小于30/11/2007，而不是禁用一些文本框.
这是我尝试的代码

hi to all

i need to check that if date of birth is less than 30/11/2007 than i need to disable some textbox.
here is my code i trying

if (dtdates.Rows[0]["dob"].ToString() < "30/11/2007")  //if dob is before 30/11/2007 than disabling
                  {
                      Txt1.Enabled = false;
                      Txt2 = false;
                      Txt2 = false;

                  }

不能应用于<类型的操作数. string和string

cannot be applied to operands of type < string and string

推荐答案

进行日期比较而不是字符串比较.

试试类似的东西:

Do date comparison instead of string comparison.

Try something like:

if (Convert.ToDate(dtdates.Rows[0]["dob"]) < Convert.ToDate("30/11/2007"))  //if dob is before 30/11/2007 than disabling 
{
                        Txt1.Enabled = false;
                        Txt2 = false;
                        Txt2 = false;
 
}
