C# - 将一串十六进制值转换为十六进制 [英] C# - Convert a string of hex values to hex
问题描述
这可能听起来很奇怪,但我的问题是,我从文本文件中获得了十六进制值的文本字符串,如下所示:
This might sound odd, but my issue is that I have a text string of hex values from a text file, like so:
"0x0f, 0x40, 0xff, ...."
数组被分隔符分割,但我现在需要做的是在十六进制中有一个字节数组:
I have stored them in an array split by the delimiters, but what I now need to do is have a byte array of what thay are in hex:
stringArray[0] = "0x0f";
byteArray[0] = 0x0f;
我该怎么做(用户可以加载文本文件,所以我不知道是什么值是),是否有某种算术我可以使用?
How do I do this (the user can load the text file, so I don't know what the values are), is there some sort of arithmetic I can use?
推荐答案
你只需要解析每个字符串。因为每一个只有一个值,你可以这样做:
You just have to parse each string. Because each one is already only one value, you can do this:
byte b;
if (byte.TryParse(s, NumberStyles.HexNumber,
CultureInfo.InvariantCulture.NumberFormat, out b))
{
// b contains the value.
}
其中s是要解析的字符串,b是结果值。
where s is the string you want to parse, and b is the resulting value.
