C＃正则表达式匹配逗号和小数

Question

I am trying regex to match decimals and commas. Code will take Bitcoin wallet account balance from API, what example would be 0.003827385, How could regex match number like that?

Answer 1

this should do it:

 Regex.Match(SearchString,"[0-9]+\.?[0-9,]*");

Answer 2

Why don't you just try a regex to match decimals?

([\d+[,\d]*]*\.\d+)|[\d+[,\d]*]*

Your question is not clear about usage of commas. Note the above regex will not match commas after decimal point.
