skip iteration outer loop in an inner loop

Question

I have two loops and when I iterating in my inner loop, I want to skip iteration for the outer loop according to my condition; continue; is only skips inner loop. Any idea?

foreach (DataRow row in dt.Rows)
 {
                for (int i = 0; i < 6; i++)
                {
                    if (row[i].Equals(DBNull.Value))
                        //skip iteration to outer loop. Go to next row.
                }
 }

You cannot jump to the next outer-loop-iteration until your inner loop ended. Is this a problem for you? If not, you can use break. Are there other instructions behind your inner loop which are inside the outer-loop too? — Koopakiller

@cihata87 write break; it will break inner loop and continue the outer loop — Akanksha Gaur

@Akanksha break; breaks from inner loop but it continues under for loop. I want to go to the } of foreach loop so I can check next row. — cihadakt

I think break will serve the purpos, if you want to get out of the inner loop and continue with the next row of the outer loop

  foreach (DataRow row in dt.Rows)
  {
            for (int i = 0; i < 6; i++)
            {
                if (row[i].Equals(DBNull.Value))
                    break;
            }
     }

You could do this:

foreach (DataRow row in dt.Rows)
{
    foreach (int i in Enumerable.Range(0, 6).TakeWhile(n => !row[n].Equals(DBNull.Value)))
    {
        // no need for `if` at all now.
    }
}
