ASP.NET looping through jagged array stored in session

Question

hey all,

im having some problems with jagged arrays stored in session for ASP.net i have some code which creates a jagged array, them populates, and then stores this populated jagged array into session

protected string[][] answersJArray;
answersJArray[0] = new string[4]("test","test1","test2","test3"};
answersJArray[1] = new string[4]("test","test1","test2","test3"};
Session.Add("answersJArray", answersJArray);

how would i loop through each jagged array in the session ?? if they were not in session i no i could do the following

    for (j = 0; j < answersJArray[1].Length; j++)
    {
        label.Text = (answersJArray[1][j].ToString());
    }

how would i do the above by looping through the session ??

thanks

Answer 1

First declare a jagged array variable and cast it from the session variable like so:

string[][] answersJArray = (string[][])Session["answersJArray"];

Then you can loop through the array like you were going to:

    for (j = 0; j < answersJArray[1].Length; j++)
    {
        label.Text = (answersJArray[1][j].ToString());
    }

Shouldn't be too tough. You can get the object out of session and cast it into a string[]. If it's a local variable, you can check its length and iterate that way. I might be misunderstanding your issue, but am I missing something by saying get the variable out of the Session map, so you can work with it as a strong-type?
