我如何找到二进制字符串

本文介绍了我如何找到二进制字符串的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我正在尝试创建一个程序，我可以用一定的数字来编写以触发多个函数。 但是我无法确定何时使用某个数字。举个例子说我有数字10我想用某种算法自动将它改成二进制字符串（00001010）。之后我想知道哪些位是打开和关闭所以我可以调用不同的函数。

I'm trying to make a program where i can write in a certain number to trigger multiple functions. But I'm having trouble identifying when a certain number is used. For an example say i have the number "10" i would like to change it to a binary string(00001010) automatically using an algorithm of some-sort. After that i would like to know which bits are on and off so i can call different functions.

推荐答案

你要找的术语不是字节形式 ，它是二进制或可能是二进制字符串。 转换它非常简单： The term you are looking for is not "byte-form", it's "binary" or possibly "binary string". Converting it is pretty easy: int i = 10; Console.WriteLine(Convert.ToString(i, 2).PadLeft(8, '0'));

但是你不需要将其转换为检查位：

But you don't need to convert it to check bits:

int i = 10; for (int j = 7; j >= 0; j--) { Console.Write(BitValue(i, j)); } Console.WriteLine(); } private int BitValue(int i, int bitNo) { return (i >> bitNo) & 1; }

或者甚至：

Or even:

int i = 10; Console.WriteLine(Convert.ToString(i, 2).PadLeft(8, '0')); for (int j = 7; j >= 0; j--) { Console.Write(BitValue(i, j) ? '*' : '.'); } Console.WriteLine(); } private bool BitValue(int i, int bitNo) { return (i & (1 << bitNo)) != 0; }
