Why is the Rank of this array 4?
You are using i for three of the 4 indices.
It could be replaced by a 2 dimensional array, and then initialize with
string [,] arraylist = new string[dt.Rows.Count, dt.Columns.count];
and just assign into:
arraylist[i, j] = ...

On this line

arraylist[i, i, i, j] = dt.Columns[j].ToString();

if i is greater than 4 it will throw the exception. That's because you have declared the array as

new string[dt.Columns.Count, 4, 4, 4];

Maybe it should be

new string[dt.Columns.Count, dt.Rows.Count, 4, 4];

? I can't tell the exact answer because I don't know what you're trying to do.

Also, by looking the name of your method (getDailyAvgRatingByCompanyId), I think this might be easier to do with a database query than with code.

Or maybe this could be done with Linq (if you're using C# 3.5 or newer)?
