เมธอด BitConverter.ToString() ใน C# ใช้สำหรับแปลงค่าตัวเลขของแต่ละ Element ใน Byte Array ให้เป็น Hexadecimal String Representation
Syntax
public static string ToString (byte[] val);
val คือ Byte Array
ตัวอย่าง
using System;
public class Demo {
public static void Main() {
byte[] arr = {0, 10, 2, 5, 32, 45};
int count = arr.Length;
Console.Write("Byte Array... ");
for (int i = 0; i < count; i++) {
Console.Write("\n" + arr[i]);
}
Console.WriteLine("\nByte Array (String representation) = {0} ", BitConverter.ToString(arr));
}
}
ผลลัพธ์
Byte Array... 0 10 2 5 32 45 Byte Array (String representation) = 00-0A-02-05-20-2D
ตัวอย่างเพิ่มเติม
using System;
public class Demo {
public static void Main() {
byte[] arr = { 0, 0, 7, 10, 18, 20, 25, 26, 32};
int count = arr.Length;
Console.Write("Byte Array... ");
for (int i = 0; i < count; i++) {
Console.Write("\n" + arr[i]);
}
Console.WriteLine("\nByte Array (String representation) = " + BitConverter.ToString(arr));
for (int i = 0; i < arr.Length - 1; i = i + 2) {
short res = BitConverter.ToInt16(arr, i);
Console.WriteLine("\nValue = " + arr[i]);
Console.WriteLine("Result = " + res);
}
}
}
ผลลัพธ์
Byte Array... 0 0 7 10 18 20 25 26 32 Byte Array (String representation) = 00-00-07-0A-12-14-19-1A-20 Value = 0 Result = 0 Value = 7 Result = 2567 Value = 18 Result = 5138 Value = 25 Result = 6681
