C# BitConverter.ToUInt64 方法使用示例
语法
public static ulong ToUInt64 (byte[] val, int begnIndex);
示例
在上面，val是字节数组，而begnIndex是val中的开始位置。
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\nByte Array (String representation) = {0} ",
BitConverter.ToString(arr));
for (int i = 1; i < arr.Length - 7; i = i + 8) {
ulong res = BitConverter.ToUInt64(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 Byte Array (String representation) = 00-00-01-03-05-07-09-0B-0F Value = 0 Result = 1083970061066240256
示例
using System;
public class Demo {
public static void Main() {
byte[] arr = { 0, 0, 1, 3, 5, 7, 9, 11, 15, 0, 1, 6, 8, 10, 20, 25, 36, 34 };
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 - 7; i = i + 8) {
ulong res = BitConverter.ToUInt64(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 0 1 6 8 10 20 25 36 34 Byte Array (String representation) = 00-00-01-03-05-07-09-0B-0F-00-01-06-08-0A-14-19-24-22 Value = 0 Result = 1083970061066240256 Value = 0 Result = 2601132293100011776
