C# BitConverter.ToUInt32() 使用方法及实例
C#中的BitConverter.ToUInt32()方法用于返回从字节数组中指定位置的四个字节转换而来的32位无符号整数。
语法
public static uint ToUInt32 (byte[] val, int begnIndex);
在上面，val是字节数组，而begnIndex是val的起始位置。
示例
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\n字节数组（字符串表示形式） = {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);
}
}
}输出结果
Byte Array... 0 3 5 10 15 2 字节数组（字符串表示形式） = 00-03-05-0A-0F-02 Value = 3 Result = 252314883
示例
using System;
public class Demo {
public static void Main() {
byte[] arr = { 0, 0, 1, 3, 5, 7, 9, 11, 15 };
int count = arr.Length;
Console.Write("Byte Array... ");
for (int i = 0; i < count; i++) {
Console.Write("\n"+arr[i]);
}
Console.WriteLine("\n\n字节数组（字符串表示形式） = {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);
}
}
}输出结果
Byte Array... 0 0 1 3 5 7 9 11 15 字节数组（字符串表示形式） = 00-00-01-03-05-07-09-0B-0F Value = 0 Result = 84082944 Value = 7 Result = 252381447
