value is greater than Byte.MaxValue. Examples The following example converts an array of unsigned 16-bit integers to Byte values. C# Copy Run ushort[] numbers = { UInt16.MinValue, 121, 340, UInt16.MaxValue }; byte result; foreach (ushort number in numbers) { try { result = Conver...
public static byte[] HexadecimalStringToByteArray(String hexadecimalString){int length = hexadecimalString.Length;byte[] byteArray = new byte[length / 2];for (int i = 0; i < length; i += 2){byteArray[i / 2] = Convert.ToByte(hexadecimalString.Substring(i, 2), 16);}...
Create the short array at half the size of the byte array, and copy the byte data in: short[] sdata =newshort[(int)Math.Ceiling(data.Length /2)]; Buffer.BlockCopy(data,0, sdata,0, data.Length); It is the fastest method by far....
