You were told how to do this at: http://www.codeproject.com/Answers/375941/How-to-pass-one-Zip-file-path-to-another-folder-th#answer1. Why did you ignore that answer?

Solution 1

Try this:

C#

private byte [] StreamFile(string filename)
{
   FileStream fs = new FileStream(filename, FileMode.Open,FileAccess.Read);

   // Create a byte array of file stream length
   byte[] ImageData = new byte[fs.Length];

   //Read block of bytes from stream into the byte array
   fs.Read(ImageData,0,System.Convert.ToInt32(fs.Length));

   //Close the File Stream
   fs.Close();
   return ImageData; //return the byte data
}

and have a look on CP article:

Why not use the File.ReadAllBytes method advocated by Mantu Singh? You've just reinvented something that MS has already provided for you.

Hi,

try Following Code

C#

private byte[] StreamFile(string filename)
    {
        FileStream fs = new FileStream(filename, FileMode.Open, FileAccess.Read);

        // Create a byte array of file stream length
        byte[] byteData = new byte[fs.Length];

        //Read block of bytes from stream into the byte array
        fs.Read(byteData, 0, System.Convert.ToInt32(fs.Length));

        //Close the File Stream
        fs.Close();
        return byteData; //return the byte data
    }

Hope this Code help U
Best Luck
Happy Coding:)

Hi I have a zip file that contains several pdfs. I used your method to convert them to byte array and send it to the method. When I open my zipfile pdfs are there but when I try to open pdfs they are corrupted. Any solution for that?

Short and simple use the following:

C#

using System.IO;

byte [] data=File.ReadAllBytes("C:\\file.zip");

Best of luck.
