You can use the overload of Array.Sort which takes a Comparison:

bla[] blas = new[] { 
    new bla() { name = "3", depth = 3 }, 
    new bla() { name = "4", depth = 4 }, 
    new bla() { name = "2", depth = 2 }, 
    new bla() { name = "1", depth = 1 }, 
};

Array.Sort(blas, (x,y) => x.depth.CompareTo(y.depth));

On this way you sort the original array instead of creating new one.
