如何在我的代码中阻止一些标点符号 [英] How to block some punctuation in my code

问题描述

大家好，

有人能指导我找出如何在我的代码中阻止一些标点符号吗?
我想输入一个浮点数，并且我不希望逗号与点."相符，但是¬
像这样的真实逗号，我绝对不知道如何利用常规¬
为此表达.
我的代码如下所示:

Hi everybody,

would somebody please guide me in finding out how to block some punctuation in my code?
I''d like to enter a floating point number and I don''t want a comma with the point ".", but ¬
the comma with the real comma like this ", I have absolutely no idea of how to utilize regular ¬
expression for this.
My code looks something like this:

float value = Convert.ToSingle(Console.Readline());
string rex = @"[0-9],";
// I don't know how to continue from here on

有人可以帮我吗?

Stefan
