How to retrieve integer values from a comma separated string array which is stored in a session?

Question

I have a string array like this

string[] BranchIds = {"1","2","3"};

and then stored it into a session

Session["BranchIds"] = BranchIds;

Now how can I retrieve this values as integers from session?

Answer 1

You can do this:

string[] branchIds = (string[])Session["BranchIds"]

Then you can iterate array for it's values.

Answer 2

You first get the values as an array of strings:

var strArr = (string[])Session["BranchIds"];

Then you can convert it to an array of int:

var intArr = Array.ConvertAll(strArr, int.Parse);

Answer 3

The 2 Question are not related, so retrieve from session is same as you add to session so if say:

string [] BranchIds = (string[])Session["BranchIds"]

then you you retrieved the array from session.

to parse a string value to integer you can use:

Int32.Parse()

so for example to parse first id:

int id = Int32.Parse(BranchIds[0]);

or you can do a for loop and convert all of them to integers, or you can store to session in integer from beginning if needed.
