I have a textbox where a user can type bytes; 0x01, 0x02, 0x03 for example.
I want the textbox text to be added in here;
byte[] offset = new byte[] { **TEXTBOXINPUTHERE** };
Android.SetMemory(0x0248C8FC, offset);
How can I accomplish this? Many examples are converting the textbox input, which I don't want.
I want a user to send a offset to a memory address. So if a user TICKS the checkbox, it inputs the textbox text that has the offset. so instead of
byte[] buffer = new byte[] { 0x60, 0x00, 0x00, 0x00 };
I want it to be
byte[] buffer = new byte[] { textbox1.text };
User would input value like "0x01" or "0x01, 0x60, 0x00, 0x00" or any other.
If you input always consists of single-byte hex values prefixed with 0x, separated by a comma (i.e. "0x01, 0x02, 0x03"), then you can simply do something like:
var input = "0x01, 0x02, 0x03";
// no validation whatsoever
var array = input
.Split(',')
.Select(i => i.Trim().Replace("0x", ""))
.Select(i => Convert.ToByte(i, 16))
.ToArray();
Or, a slightly less strict version would split on different separator characters (e.g. commas, spaces, tabs):
private static byte[] GetByteArrayFromHexString(string input)
{
return input
.Split(new[] { ',',' ','\t' }, StringSplitOptions.RemoveEmptyEntries)
.Select(i => i.Trim().Replace("0x", ""))
.Select(i => Convert.ToByte(i, 16))
.ToArray();
}
This should work for several different inputs, so that your users don't have to type all that unnecessary stuff:
// all these variants produce the same output
GetByteArrayFromHexString("0x01, 0x02, 0x03") // --> new byte[] { 1, 2, 3 }
GetByteArrayFromHexString("0x01 0x02 0x03") // --> new byte[] { 1, 2, 3 }
GetByteArrayFromHexString("01 02 03") // --> new byte[] { 1, 2, 3 }
