C#: Copying 2 buffers

Use Buffer.BlockCopy method

<span style="color:Blue;">public</span> <span style="color:Blue;">static</span> <span style="color:Blue;">void</span> BlockCopy(
	Array src,
	<span style="color:Blue;">int</span> srcOffset,
	Array dst,
	<span style="color:Blue;">int</span> dstOffset,
	<span style="color:Blue;">int</span> count
)
Example:

byte[] dataRcvd = new byte[20];
byte[] commBuffer = new byte[5];
Buffer.BlockCopy(commBuffer,0, this.dataRcvd,0, 5);
