How to read a range of bytes from a bytearray in c#

Question

I have to read a range of bytes from a byte array. I have the starting position and the ending position to read.

-(NSData *) getSubDataFrom:(int)stPos To:(int)endPos withData:(NSData *) data{
    NSRange range = NSMakeRange(stPos, endPos);
    return [data subDataWithRage:range];
}

The above code in ObjectiveC reads the range of data(bytes) from a NSData(byteArray). Is there any equivelent method in c# to do the same. or how else we can do this. Please advise!

Answer 1

What do you mean by read? Copy a range of bytes into another byte array?

var mainArray = new byte[] { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 };
var startPos = 5;
var endPos = 10;
var subset = new byte[endPos - startPos + 1];
Array.Copy(mainArray, startPos, subset, 0, endPos - startPos + 1);
