how to set date time field to null

I am using .net 4.0. I have interface with date time fields like

 DateTime FromDate
    {
        get;
        set;
    }
    DateTime ToDate
    {
        get;
        set;
    }

I want to set the value to this to null in my user interface like

IUser m_user = new User();
  m_user.FromDate = DBNull.value;

In shows error , like cannot convert null to datetime.

How to assign null to datetime?

Thanks , pooja

For DateTime instead of null using DateTime.MinValue

You can't do that, as DateTime can't get null value because it's value type.

One way is changing your code to use Nullable type instead:

DateTime? FromDate
{
    get;
    set;
}

Then it can be null:

m_user.FromDate = null;
