推荐答案

我不会给您转换后的代码，但是让我来帮助您编写它.
第一句话，
DateTime DOB = Convert.ToDateTime(txtDOB.Text, format);
从文本框中获取值，然后使用JavaScript Date Object将其转换为日期.所以，

I won''t give you the converted code, but let me help you write it.
First statement,
DateTime DOB = Convert.ToDateTime(txtDOB.Text, format);
Get the value from the textbox and use JavaScript Date Object to convert it into date. So,

var txtDOB = document.getElementById('<%= txtDOB.ClientID %>').value;
var DOB = new Date(txtDOB);

在这里，我正在使用日期对象的此重载-new Date(dateString);
我将验证部分留给您.

第二句话，
DateTime MatureDate = DOB.AddYears(18);
JavaScript没有AddYears或类似功能.但是您可以在JavaScript中轻松添加年份.这是您的操作方法:

Here I am using the this overload of the date object - new Date(dateString);
I leave the validations part to you.

Second statement,
DateTime MatureDate = DOB.AddYears(18);
JavaScript doesn''t have a AddYears or similar function. But you can easily add years to a date in JavaScript. Here is how you do it:

var myDate = new Date();
myDate.setFullYear(myDate.getFullYear() + 18);

因此，您只需要为DOB做就可以了.即

So you just have to do it for DOB. i.e

DOB.setFullYear(DOB.getFullYear() + 18);

最后是第三行，
int temp = DateTime.Compare(MatureDate, System.DateTime.Now);

比较日期并不是一项艰巨的任务. JavaScript日期对象 [
希望这可以帮助！ :thumbsup:

And finally the third line,
int temp = DateTime.Compare(MatureDate, System.DateTime.Now);

Comparing dates aren''t a big task. JavaScript Date Object[^]
Scroll down to the example "Compare Two Dates".

Hope this helps! :thumbsup:
