+ bytesPerLine * 3 // - 2 digit for the hexadecimal value and 1 space
+ (bytesPerLine - 1) / 8 // - 1 extra space every 8 characters from the 9th
+ 2; // 2 spaces
var lineLength = firstCharColumn
+ bytesPerLine // - characters to show the ascii value
+ Environment.NewLine.Length; // Carriage return and line feed (should normally be 2)
var line = (new string(' ', lineLength - Environment.NewLine.Length) + Environment.NewLine).ToCharArray();
var expectedLines = (bytesLength + bytesPerLine - 1) / bytesPerLine;
var result = new StringBuilder(expectedLines * lineLength);
for (var i = 0; i < bytesLength; i += bytesPerLine)

line[2] = hexChars[(i >> 20) & 0xF];
line[3] = hexChars[(i >> 16) & 0xF];
line[4] = hexChars[(i >> 12) & 0xF];
line[5] = hexChars[(i >> 8) & 0xF];
line[6] = hexChars[(i >> 4) & 0xF];
line[7] = hexChars[(i >> 0) & 0xF];
var hexColumn = firstHexColumn;
var charColumn = firstCharColumn;
for (var j = 0; j < bytesPerLine; j++)

hexColumn++;
if (i + j >= bytesLength)

var b = buffer[i + j];
line[hexColumn] = hexChars[(b >> 4) & 0xF];
line[hexColumn + 1] = hexChars[b & 0xF];
line[charColumn] = b < 32 ? '·' : (char)b;
}
