Sorting array of object by name (multi dimensional)

Question

how can i sort a array of objects by name.

Example of how the array is constructed array:

     object[] o = new object[items.Count+(row-exists)];
     int i = 0;
     for(i=0; i<items.Count;i++)
     {
    XmlNode item = items[i];

    o[i] = new object[5];
    ((object[])o[i])[0] = Safe(item, "ows_Title");
    ((object[])o[i])[1] = Safe(item, "ows_Column5");
    ((object[])o[i])[2] = ((string)Safe(item, "ows_Column7")).Trim(new char[] {'\''});
    ((object[])o[i])[3] = Convert.ToDouble(Safe(item, "ows_Column12"), provider);
    ((object[])o[i])[4] = Convert.ToDouble(Safe(item, "ows_Column9"), provider);
}

i want the 'o' to be sorted based on the value of ((object[])o[i])[0] .

Thank you

the array 'o' contains objects with a new array, am I right? I want the 'o' to be sorted based on the value/(string) of the index 0 of the 2nd array. I'm not sure if I managed to explain myself any better. — cap

Why don't you store your object in generic SortedList, with object's primary key as list's key or choose key as per your requirements? — FIre Panda

I think I understand. The linq below should do what you require.

var sortedResult = o.OrderBy(x => ((object[])x)[0]).ToArray();

However, I would look at using a differt data structure. Can you create a new type to encapsulate what the second array represents? For example:

class MyObject
{
  Safe Title {get; set;}
  Safe Column5 {get; set;}
  String Column7 {get; set;}
  double Column9 {get; set;}
  double Column12 {get; set;}
}

You can then use a SortedList to store the new objects.

Thanks IndigoDelta, looks like you understand what I'm in need of. unfortunately I don't have access to linq, and I'm on a 2.x framework.

I pity the man without access to linq. You can write your own sorting algorithm if required. Have a look some examples. There is a library on CodeProject of sorting algorithms which might help you
