使用以下Regex:

Use the following Regex:

public static Regex regex = new Regex(
    @"\<td.*\>(?<num>.*)\<\/td\>",
    RegexOptions.IgnoreCase
    | RegexOptions.Multiline
    | RegexOptions.IgnorePatternWhitespace
    | RegexOptions.Compiled
    );

这将为您提供名为num的命名匹配.

Which will give you named matches called num.

Mehdi Gholam 给出的解决方案1非常好.唯一的问题是regex 中给出的.*会捕获包括< and >在内的所有内容，因此我们只能得到最后一个数字，即130.0.因此，必须将.*替换为[^<>]*.
此外，在用matches捕获所有数字之后，在每个匹配项中捕获的数字将为Groups[1].因此，OP在上述注释中声明的Groups[2], Groups[3]可能无法给出正确的结果.
因此，以下代码可用于根据需要设置值.

The Solution 1 given by Mehdi Gholam is excellent. Only thing is that .* given in the regex captures everything including < and > so that we get only the last number i.e. 130.0. So, .* has to be replaced by [^<>]*.
Further, after capturing all the numbers with matches, the captured number will be Groups[1] in each match. So, Groups[2], Groups[3] stated by OP in the comment above, may not give the correct result.
Hence, the following code can be used to set the values as required.

Regex regex = new Regex(@"\<td[^<>]*\>([^<>]*)\<\/td\>",RegexOptions.IgnoreCase | RegexOptions.Multiline);
var matches = regex.Matches(comp);
if (matches.Count==3){
    string v=matches[0].Groups[1].Value;
    string r=matches[1].Groups[1].Value;
    string s=matches[2].Groups[1].Value;
}
