เมธอด BitConverter.ToUInt32() ใน C# ใช้สำหรับแปลง 4 ไบต์จากตำแหน่งที่ระบุใน Byte Array ให้เป็น Unsigned 32-bit Integer (uint)
Syntax
public static uint ToUInt32 (byte[] val, int begnIndex);
val คือ Byte Array, begnIndex คือตำแหน่งเริ่มต้นใน val
ตัวอย่าง
using System;
public class Demo {
public static void Main() {
byte[] arr = { 0, 3, 5, 10, 15, 2 };
int count = arr.Length;
Console.Write("Byte Array... ");
for (int i = 0; i < count; i++) {
Console.Write("\n" + arr[i]);
}
Console.WriteLine("\n\nByte Array (String representation) = {0} ", BitConverter.ToString(arr));
for (int i = 1; i < arr.Length - 1; i = i + 4) {
uint res = BitConverter.ToUInt32(arr, i);
Console.WriteLine("\nValue = " + arr[i]);
Console.WriteLine("Result = " + res);
}
}
}
ผลลัพธ์
Byte Array... 0 3 5 10 15 2 Byte Array (String representation) = 00-03-05-0A-0F-02 Value = 3 Result = 252314883
