将字符串更改为字节数组而不进行转换

Question

我有一个JSON格式的对象，字节数组以字符串形式出现。我需要将该字符串更改为字节数组，但不转换字符串。

    static byte[] GetBytes(string str)
    {
        return str.Select(Convert.ToByte).ToArray();
    }

上面的代码解决了这个问题，不幸的是它仍然将每个char转换为它的相应字节。

对于完整性，这是我的字符串

我需要将其更改为字节数组，例如

['P'，'C'，'F']等，没有将每个字符转换为它的相应字节

在该问题中，正在转换字符串。 标题中我不想转换

Answer 1

假设这是您的实际问题描述：

  

我有一个base64编码的字符串，我希望将其转换为字节数组，其中每个字节包含base64字符串中一个字符的ASCII代码。

然后你可以很容易地做到这一点：

byte[] characterBytes = Encoding.ASCII.GetBytes(input);

因为base64字符串中使用的字符都低于Unciode代码点127，所以它们都可以用Encoding.ASCII获得的单个字节表示。

事实上，如果这是您的实际问题描述，则表明此问题与C# Convert a string to ASCII bytes重复。
