C#

DateTime maxDate = dt.AsEnumerable()
            .Where(r => r.Field<string>("Column1") == "someValue")
            .Select(r => r.Field<string>("column2"))
            .Max();

ypu can use LINQ for this purpose, but i think this is fastest way as compare to LINQ

C#

int minAccountLevel = int.MaxValue;
int maxAccountLevel = int.MinValue;
foreach (DataRow dr in table.Rows)
{
    int accountLevel = dr.Field<int>("AccountLevel");
    minAccountLevel = Math.Min(minAccountLevel, accountLevel);
    maxAccountLevel = Math.Max(maxAccountLevel, accountLevel);
}
