我怎么计算一下在狗后的性质数目
原标题:How do I count number of characters after dot

string num ="123.12400";

之后,我需要获得一些特性。

最佳回答
num.Length - num.IndexOf(".")-1;
问题回答
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;
