I have an Asp.Net2 application using C# that allows users to upload SWF files in my site and i need to check if the SWF file contains specific two lines of code, if it contains it so i will alow the SWF file to be uploaded and if not exists i will need to insert this two lines of code in the SWF file.
How can i read SWF file code from C# and update it can any one help me?
Note:I need to read the content of the SWF file not the header
