I have a byte array and want to split this with * char I am C++/Qt developer i can do this easy with this code in Qt
QByteArray byteArray;
QList<QByteArray> byteArrayList;
byteArray = file.readAll();
file.close();
byteArrayList = byteArray.split('*');
How can i split a byte array with char in C# ?
byte[] bytes = File.ReadAllBytes("yourtextfile.txt");
string[] x = Encoding.UTF8.GetString(bytes).Split('*');
Change encoding if needed.
I'm not sure anything is inbuilt for that, since it isn't a common scenario; however you can search by index:
(all use of string here is purely for illustration; the actual split code doesn't use that)
static void Main()
{
// pretend this isn't text
byte[] bytes = Encoding.ASCII.GetBytes("askdjhkas*hdaskjdhakjshdjkahs*dkujyash");
foreach(var chunk in Split(bytes, (byte)'*'))
{
// cheating with text to see if it worked
var s = Encoding.ASCII.GetString(chunk.Array, chunk.Offset, chunk.Count);
Console.WriteLine(s);
}
}
static IEnumerable<ArraySegment<byte>> Split(byte[] data, byte splitBy)
{
int start = 0, end;
while((end = Array.IndexOf<byte>(data, splitBy, start)) > 0)
{
yield return new ArraySegment<byte>(data, start, end - start);
start = end + 1;
}
end = data.Length;
if ((end - start) > 0)
{
yield return new ArraySegment<byte>(data, start, end - start);
}
}
Note: this would be a great scenario for "span" when that lands.
string.Split but for arrays?)
List<ArraySegment<byte>>> ? if so: var bytesList = Split(bytes, (byte)'*').ToList();. As I say, "span" would be idea for this and would avoid extra allocs. If you must duplicate all the pieces, it can be done, sure
QByteArray? what API does that expose? that's not an inbuilt type, so... what happens with your code? doesbyterArray.split((byte)'*');work?byte[] byteArray = ...?
