num.Length - num.IndexOf(".")-1;
num.SubString(num.IndexOf(".") + 1).Length;
只要在之后总是有一些果园,我们就会工作。
string[] s = num.split( . );
int count = s[1].Length;
这应当是最可读的形式。
num.SkipWhile(c => c != . ).Skip(1).Count();
var a = 12345.67;
var after_dot = (a.toString().split(".")[1]).length;
var before_dot= (a.toString().split(".")[0]).length;
