A variable of type DateTime in C# cannot be assigned to a null value. However, in some cases, we do need to do that.
In such cases, we can use the Nullable version of DateTime. Two suggested ways of assigning a null value to DateTime are:
1. Nullable<DateTime> currentDate = null
2. DateTime? currentDate = null
One Problem I faced while using the Nullable DateTime is that, when I tried to convert the date into string I was not able to specify the any format as there is no overload for DateTime?.ToString() which takes one or more arguments like DateTime.ToString().
Nullable are actually Generic, Value properly gives directly the DateTime inside the Generics.
This is what works.
delvDate = DateTime.Now;
string str = delvDate.Value.ToString(“yyyy-MM-dd”);
Following is the link which talks about the workarounds and Nullable in .Net2.0
