Passing bytearray by ref in C#

Hi

You can use also following code for Passing bytearray by ref in C#.you can refer this.

byte[] tmpArray = new byte[10];

for (int i = 0; i < 10; i++) { tmpArray[i] = (byte)i; }

Array ar = tmpArray;

myactivexControl.test2(ref ar);

refer article

Thanks a lot for your reply shankey
Actually my problem is
string fileName = "rgb.jp2";
FileStream fs = new FileStream(fileName, FileMode.Open, FileAccess.Read);
BinaryReader br = new BinaryReader(fs);
long numBytes = new FileInfo(fileName).Length;
byteData = br.ReadBytes((int)numBytes); /// Now byteData contains image bytes info

//now if i use
codec.OpenFile("rgb.jp2"); /// Shows a file in control codec
///
//// but i want to do it by using memory as i am using all this in a live stream
/// i cant write all this in a file becuase it will consume time
//codec.OpenMemory is the function that will do it but i am unable to pass parameters in it
// It requires parametersvoid codec.OpenMemory (ref byte src_buff, int src_buff)
// While i only have a bytearray named byteData which holds bytes containing image info. I cant pass byte array as a reference i can only pass a single byte
 
I have also uploaded the source code.

hi Hassan,

I tried the following code and by default the byte array is passed by reference you can try following code.

namespace byteArray
{
    class Program
    {
        static void Main(string[] args)
        {
            byte[] byteData;
            string fileName = @"C:\pic3.jpeg";
            FileStream fs = new FileStream(fileName, FileMode.Open, FileAccess.Read);
            BinaryReader br = new BinaryReader(fs);
            long numBytes = new FileInfo(fileName).Length;
            byteData = br.ReadBytes((int)numBytes);
            openMemory(byteData);

            for (int i = 0; i < 10; i++)
            {
                Console.WriteLine("{0}:{1}", i, byteData[i]);
            }
        }

        private static void openMemory(byte[] b)
        {
            for (int i = 0; i <10; i++)
            {
                Console.WriteLine("{0}:{1}", i, b[i]);
                b[i]++;
            }

        }
    }
}

And if i am not able to understand your problem clearly then plz provide some more details like the prototype of the openmemory function...
