如果我在分子中有int号,我将从my1.cs做一个方法,如果我在分母/分母中有双号,我将从另一个名为my2.cs的类中做方法.我如何编码IF,

if (number = int) {//; bla bla bla...} 要么

if (number = double) {//; bla bla bla...}

如何编写if语句:if (numerator.GetType==int){...}？

主要的麻烦在于:我从文本框中读取了nominator和denominator,其中var dr1 = textBox1.Text.Split('/'); !拆分,但我怎么能从字符串gettype ???
