Byte array to textboxes

[aannn]

Hi,
In my application there is a structure that holds 200 parameters for 200 tests. These structure is converted to byte array . I want to write this byte array to a file in save button and when I click open button, this file must open and write these bytes to corresponding text boxes. How it possible.??

What are you having problems with?
Writing to/saving the file?
Opening the file?
Reading the contents?
Displaying the contents?
