推荐答案

首先，UTF-8是一种编码，但十六进制和十进制不是：它们是数字格式，可能包含也可能不包含在您的文件中。



如果您的意思是您的文件包含文本格式的数字组：

Firstly, UTF-8 is an encoding, but "hexadecimal" and "decimal" aren't: they are numeric formats, which may or may not be contained in your file.

If you mean that your file contains groups of numbers in a text format:

1234,1A7F
5678,00FF
...

你想将它们转换成数学值，你可以用数学方法操作，然后你必须将每个数字分开并解析它。 br />
对于十六进制值：

And you want to convert them into numeric values that you can manipulate mathematically, then you have to separate each number, and parse it.
For hexadecimal values:

string inp = "1A7F";
int x = Convert.ToInt32(inp, 16);

对于十进制值：

For decimal values:

string inp = "1234";
int x = int.Parse(inp);

或

Or

string inp = "1234";
int x;
if (int.TryParse(inp, out x))
    {
    ...
    }
