你如何将字符串转换为ASCII码为二进制在C＃中？ [英] How do you convert a string to ascii to binary in C#?

问题描述

前阵子（高中一年级）我问一个很好的C ++程序员谁是小辈做一个简单的应用程序将字符串转换为二进制。他给了我下面的code样品：<​​/ P>

A while back (freshman year of high school) I asked a really good C++ programmer who was a junior to make a simple application to convert a string to binary. He gave me the following code sample:

void ToBinary(char* str)
{
    char* tempstr;
    int k = 0;

    tempstr = new char[90];

    while (str[k] != '\0')
    {
	    itoa((int)str[k], tempstr, 2);
	    cout << "\n" << tempstr;
	    k++;
    }

    delete[] tempstr;
}

所以我想我的问题是我如何得到一个相当于在C＃中itoa功能？或者，如果没有一个我怎么能达到同样的效果？

So I guess my question is how do I get an equivalent to the itoa function in C#? Or if there is not one how could I achieve the same effect?

推荐答案

这是很容易用C＃做的。

This is very easy to do with C#.

var str = "Hello world";

With LINQ
foreach (string letter in str.Select(c => Convert.ToString(c, 2)))
{
  Console.WriteLine(letter);
}

Pre-LINQ
foreach (char letter in str.ToCharArray())
{
  Console.WriteLine(Convert.ToString(letter, 2));
}
