提问by Pinchy
Assume I have a string "2.36" and I want it trimmed to "236"
假设我有一个字符串“2.36”，我想把它修剪为“236”
I used Trim function in example
我在示例中使用了 Trim 功能
String amount = "2.36";
String trimmedAmount = amount.Trim('.');
The value of trimmedAmount is still 2.36
trimmedAmount 的值仍然是 2.36
When amount.Trim('6');it works perfectly but with '.'
当amount.Trim('6');它完美运行但带有 '.' 时

我做错了什么？

String.Trimremoves leading and trailing whitespace. You need to use String.Replace()
String.Trim删除前导和尾随空格。你需要使用String.Replace()
Like:
喜欢：
string amount = "2.36";
string newAmount = amount.Replace(".", "");

Two ways :
两种方式：
string sRaw = "5.32";
string sClean = sRaw.Replace(".", "");
Trim is make for removing leading and trailings characters (such as space by default).
Trim 用于删除前导和尾随字符（例如默认情况下的空格）。

If you want to remove everything but the digits:
如果要删除除数字以外的所有内容：
String trimmedAmount = new String(amount.Where(Char.IsDigit).ToArray());
or:
或者：
String trimmedAmount = Regex.Replace(amount, @"\D+", String.Empty);
