storing array in session variable

[mechweb]

Hi all, I can successfully store an array in a session variable like so:
string[] arr1 = new string[10];

Session["myarray"] = arr1;

But, when I try to display the elements (using the code below) on another
page I get this error:

txtmyarray.Text = Session["myarray"][0];

Cannot apply indexing with [] to an expression of type 'object'

The weird thing is that the code works fine in the immediate window while
debugging. Any thoughts?

Re: storing array in session variable

hi,

My advise is that you should read an introductory book to c# , this is
based on both your questions.

This will solve your problem:
txtmyarrat.Text = ((string[])Session["myarray"])[0];

cheers,

Hi,

you've got to cast it back to an array type.

txtmyarray.Text = (string)((Array )Session["myarray"])[0]
or
txtmyarray.Text = ((string[])Session["myarray"])[0]

Session["myarray"] is returning type object. Cast it to string[] before
trying to access it as such.
