Hi,
There are 2 grids in which i have to display data in sorted form
for 1st grid - data with high price
for 2nd grid - data with low value

i am getting the data in a string array (string[5][4])
i.e. data[0-5]{string []{"value","high price","low value","qty"}}

e.g.

string[][] newval = new string[][] { 
    new string[]{"12","113.12","121.90","12"},
    new string[]{"12","111.15","121.95","12"},
    new string[]{"12","115.16","121.92","12"},
    new string[]{"12","116.13","121.98","12"},
    new string[]{"12","114.11","121.95","12"}};

each time data is coming in the format above & with 5 rows i have to fill these grids as(first 2 values for grid 1 & next 2 values for grid 2)

grid 1

high price-- value

grid 2

low value -- qty

i have to create a string array of 10 from the coming data as string[10][4] thus to display 10 rows in each grid condition grid 1 to be sorted on high price(data type double) and grid2 to be sorted on low value (data type double).

Solution 1

Hi,

Is this what you're asking?

C#

var list1 = newval.Select(x => new String[] { x[1], x[0] });
var list2 = newval.Select(x => new String[] { x[2], x[3] });

Hope it helps.

Edit: I'm missing the sort: List<t>.Sort[^]

Didn't get this.. what will exactly this will do??
will this sort double values accurately which we are getting as string??

It will split you matrix into 2 arrays:

list1 will contain the high prices and the values
list2 will contain the low prices and the quantities

Then, you'll just need to sort those two lists as _Amy said.

Solution 2

Hi,
Try this:

C#

int[,] array = new int[3, 3] { { 1, 4, 2 }, { 4, 5, 1 }, { 7, 3, 8 } };
int[,] sortedByFirstElement = array.OrderBy(x => x[0]);
int[,] sortedBySecondElement = array.OrderBy(x => x[1]);
int[,] sortedByThirdElement = array.OrderBy(x => x[2]);

Refer this[^] also.
