从印刷的asciiArt字符中获取一封信

Question

我有一个asciiArt从A到Z 打印（使用＃）字符的方法。它称为asciiArt.printChar (char c)。

这是一个测验问题，所以我没有此方法的定义。我需要的是获取printChar方法返回的打印字符串，搜索并返回与此字符串匹配的正确字符。

Answer 1

Does this work?

char ScanChar(string art)
{
    // Iterate over each character from A to Z.
    for (char c = 'A'; c <= 'Z'; c++)
    {
        // Check to see if the character corresponds with the ASCII art.
        if (asciiArt.printChar(c) == art)
        {
            // Return the character if it does.
            return c;
        }
    }

    // Optionally use a null character to indicate that the string passed
    // doesn't correspond to any valid ASCII art.
    return (char)0;
}

Instead of returning a null character to handle a bad string being passed, you could also throw an error like this.

throw new ArgumentException("The string does not correspond to valid ASCII art.");

Also keep in mind that C# methods are conventionally capitalized.
