推荐答案

检查一下： http://www.dotnetperls.com/regex-split-numbers [ ^ ]

正则表达式可能是要走的路：

A regex is probably the way to go:

Match m = Regex.Match("01XWed", "\d+");
if (m.Sucess)
   {
   int value = int.Parse(m.Value);
   ...
   }

public void getNum()
{
	string a = "01xwed";
	string value = "";
	if (a(0).ToString == "0") {
		value = 0;
	}
	value = value + int.Parse(Regex.Replace(a, "[^\\d]", ""));
}

再见
