C＃模式匹配 [英] C# pattern matching

问题描述

我有点新的C＃中，我要寻找一个字符串匹配模式做到以下几点，

我有这样

$ B字符串
$ b

这本书将在数量
接收唐宁街11号
展出，并将于关键医疗

$ b将出席$ b

我需要创建一个span标记突出使用startIndex和长度有一定的文字片段，

有关例如，

1. 的startIndex = 3，长度= 10


2. 的startIndex = 8，长度= 8

我需要动态地创建一个span标记，也可以创建一个对于交叉口单独span标签

在这种情况下，

 在< ;跨度ID ='span1'颜色=蓝>本书< / SPAN> <跨度ID ='intersectionSpan'颜色粉红=>将< / SPAN> <跨度ID = SPAN2'颜色='黄色'>展出< / SPAN> 
  

任何人遇到任何种类的设计模式或smiler问题

请指教

解决方案

我不认为这德兴模式相关，但我会看什么ü问道自定义控件

正如你所知道的标签控件将呈现为一个跨度，以便开始进行，例如新的控制customlabel从它里面的标签控制和克里特功能继承它接受地点（startIndex和长度）和颜色（红，黄）

让我们说我们有控制这里面功能

 私人字符串AddSpan（字符串originalString，INT []的位置，串色）
 {
字符串old = originalString.Substring（位置[0] ，位置[1]）; 
线=中newstr的String.Format（<跨度ID ={0}颜色={1}>中，idUWant，颜色）; 
 originalString = originalString.Replace（老，中newstr）; 
返回originalString; 
} 
  

的

originaltext是这本书将在前台唐宁街11号展出
，将被重点医疗出席

的位置是简单的2维整数数组第一个将是开始索引和第二个将是长度，颜色参数是颜色字符串

我认为这是更好地使像一类holiding的参数的资料容器只喜欢startIndex和长度和颜色的一些属性，使之更容易阅读和维护

I am bit new to c#, i am looking for a string matching pattern to do the following,

I have a string like this

The book will be showcased at a reception in Number 11 Downing Street and will be attended by key healthcare

i need to create a span tag to highlight some text fragments using startIndex and length,

for an example,

1. startIndex = 3, Length = 10
2. startIndex = 8, Length = 8

i need to create a span tag dynamically and also create a separate span tag for intersections

in this case,

The < span id= 'span1' color='blue'> book < /span> < span id='intersectionSpan' color= pink > will </ span> < span id '= span2' color = 'yellow' > be showcased </ span>

anyone has come across any kinds of design pattern or smiler problems

please advice

解决方案

I don't think this related to desing pattern but i would look to what u asked as custom control

as you know the label control will render as a span so start to make new control customlabel for example inherit it from the label control and creta functions inside it to accept the locations (startindex and length ) and the color (red , yellow )

let's say we have this function inside the control

 private string AddSpan(string originalString, int[] location, string color)
    {
        string old = originalString.Substring(location[0], location[1]);
        string newStr = string.Format("<span id= '{0}' color='{1}'>", "idUWant", color);
        originalString = originalString.Replace(old, newStr);
        return originalString ; 
    }

the originaltext is The book will be showcased at a reception in Number 11 Downing Street and will be attended by key healthcare

the location is simple 2 dimension array of integer the first one will be the start index and second one will be length , color parameter is color string

i think it's better to make data container for the paramters like a class holiding only a few properties like startindex and length and color to make it easier for reading and maintaining
