You can check for any type of variable
C#
string ot ="adas";
if (ot is string)
   return string;
else if (ot is int)
   return int;

u can use int.TryParse for this:
C#
foreach (DataRow dr in datatable.Rows)
{
    int temp;

    bool flag = int.TryParse(dr["ProjectId"].ToString(), out temp);

    if (flag == true)
    {
        //if success, i.e. ProjectId is int. its value will be in variable temp
    }
    else
    {
        //if failure, i.e ProjectId is not integer
    }
}
