Adding byte to byte array

There are two methods. either to create a new array or resize the existing array;

To resize existing array, do this;

Array.Resize(ref fileBytesArray, fileBytesArray.Length + 1);

To create a new array from existing one and resize, do this;

bArray = AddByteToArray(bArray,  newByte);

Here is the method;

public byte[] AddByteToArray(byte[] bArray, byte newByte)
{
    byte[] newArray = new byte[bArray.Length + 1];
    bArray.CopyTo(newArray, 1);
    newArray[0] = newByte;
    return newArray;
}
