I will post the code I have to convert from Int64 to byte[4] and from byte[4] to Int64.
Feel free to comment on the code. I am still searching of a simpler way of doing this:

System.Int64 paraInt64 = 4294967295;
System.Byte[] myByte = new System.Byte[4];

myByte[0] = Convert.ToByte(paraInt64/(256*256*256));

if (paraInt64/(256*256) <= 255)
  myByte[1] = Convert.ToByte(paraInt64/(256*256));
else
  myByte[1] = Convert.ToByte((paraInt64/(256*256))%256);

if (paraInt64/(256) <= 255)
  myByte[2] = Convert.ToByte(paraInt64/256);
else
  myByte[2] = Convert.ToByte((paraInt64/256)%256);

myByte[3] = Convert.ToByte(paraInt64%256);

System.Int64 iValue; 
iValue = (Convert.ToInt64(myByte[0]) * (256*256*256)) + (Convert.ToInt64(myByte[1]) * (256*256)) + (Convert.ToInt64(myByte[2]) * 256) + (Convert.ToInt64(myByte[3]));
