Date formatting on DateTime?

[Shikari Shambu]

I have DateOfBirth declared as

DateTime? DateOfBirth;

DateOfBirth.ToSTring("yyyyMMdd");

gives an error - no overload method ToString() takes 1 arguments.

However, if I were to declare DateOfBirth as

DateTime DateOfBirth;

this works without an error.

How do I get the formatting to work on the nullable DateTime I.e DateTime?
DateOfBirth;

TIA

I have DateOfBirth declared as

DateTime? DateOfBirth;

DateOfBirth.ToSTring("yyyyMMdd");

Use DateOfBirth.Value.ToString("yyyyMMdd");

Figured this out. Have to explicitly give .Value.

DateOfBirth.Value.ToString("yyyyMMdd");

Time to learn about how to use nullable variables?

string text = DateOfBirth.HasValue ?
DateOfBirth.Value.ToString("yyyyMMdd") : "-";

Check to make sure it's not null, then cast it to DateTime.
