我怎样才能避免更换> =使用> = [英] How Can I Avoid Replacing >= With > =

问题描述

我正在尝试验证编码中的运算符。键入输入后我需要用空格替换输入正常工作，但这是一个问题，如果我试图用空格替换> =它打破两个标准> =这是错的。我无法从编码中删除logicdata.Replace（<，<）.Replace（>，>），因为我也需要它。

所以请建议我如何避免它。



以下是编码。



var validatelist = logicdata.Replace（<，<）.Replace（>，>）.Replace（ > =，> =）。放置（{，{）。放置（}，}）。放置（），））。放置（（ ，（）。替换（+，+）。替换（ - ， - ）。替换（&&，&&）。替换（==，== ）.Replace（||，||）。Replace（！=，！=）。Replace（< =，< =）.Replace（&=， &=）。放置（<< =，<< =）。放置（>> =，>> =）;



提前感谢。

Hi,

I am trying to validate operators in my coding. After typing input I need to replace input with space which is working fine but here is one problem, if I am trying to replace >= with space it is breaking in two par > = which is wrong. I can't remove "logicdata.Replace("<", " < ").Replace(">", " > ")" from coding as I need this also.
So please suggest How can I avoid it.

Below is the coding.

var validatelist = logicdata.Replace("<", " < ").Replace(">", " > ").Replace(">=", " >= ").Replace("{", " { ").Replace("}", " } ").Replace(")", " ) ").Replace("(", " ( ").Replace("+", " + ").Replace("-", " - ").Replace("&&", " && ").Replace("==", " == ").Replace("||", " || ").Replace("!=", " != ").Replace("<=", " <= ").Replace("&=", " &= ").Replace("<<=", " <<= ").Replace(">>=", " >>= ");

Thank in advance.

推荐答案

首先，我不得不说我无法想象你需要什么样的场景在这里。



但是，如果我必须这样做：

First, I have to say that I have trouble imagining what kind of scenario you'd need to this in.

But, if I had to do this:

.Replace(">=", "GTE")
.Replace("<=", "LTE")
.Replace("<<=", "SFL")
.Replace(">>=", "SFR")

.Replace("<", " < ")
.Replace(">", " > ")

.Replace("GTE", " >= ")
.Replace("LTE", " <= ")
.Replace("SFL", " <<= " )
.Replace("SFR", " >>= ");
