conversion form self defined type to byte array

[stonee74]

Hi,

How can I convert a self defined datatype into a byte array?

thanks a lot,

for example this struct: (header of a bitmap file)
struct BitmapFileHeader
{
public ushort bfType;
public int bfSize;
public ushort bfReserved1;
public ushort bfReserved2;
public int bfOffBits;
public static int Length = 14;

public byte[] ToByteArray()
{
byte[] ByteArray = new byte[Length];
BitConverter.GetBytes(bfType).CopyTo(ByteArray,0);
BitConverter.GetBytes(bfSize).CopyTo(ByteArray, 2);
BitConverter.GetBytes(bfReserved1).CopyTo(ByteArray, 6);
BitConverter.GetBytes(bfReserved2).CopyTo(ByteArray, 8);
BitConverter.GetBytes(bfOffBits).CopyTo(ByteArray, 10);
return ByteArray;
}

public void FromByteArray(byte[] ByteArray)
{
bfType = BitConverter.ToUInt16(ByteArray, 0);
bfSize = BitConverter.ToInt32(ByteArray, 2);
bfReserved1 = BitConverter.ToUInt16(ByteArray, 6);
bfReserved2 = BitConverter.ToUInt16(ByteArray, 8);
bfOffBits = BitConverter.ToInt32(ByteArray, 10);
}
};

I used it to read and write this structure to a file.
