Question

I have a string variable st and i have assign this string variable to output coming form data table by using this statement

string st;

if(dt!=null)
{
    if(dt.rows.count> 0)
    {
        st = dt.Rows[3]["timeslot_StartTime"].ToString();
    }
}

now i want to convert this string variable to date time property and i have done this one by using the below statement

DateTime pt1 = DateTime.Parse(st);

but it shows error at st saying that use of unassigned local varaible "st".

Answer 1

Probably you are using the variable in a different scope from the one where it’s assigned, like

string st;
if (condition) {
    st = dt.Rows[3]["timeslot_StartTime"].ToString();
}
DateTime pt1 = DateTime.Parse(st);

So, st is not always initialized (it is only if the if condition is verified). Try instead

string st;
if (condition) {
    st = dt.Rows[3]["timeslot_StartTime"].ToString();
    DateTime pt1 = DateTime.Parse(st);
}
