我如何解析网址？

问题描述

你好，



什么是解析字符串并找出特定单词的最佳方法。



例如，



www.abc.com/public/test/this_is_test.php



现在在上面的网址中，我需要查找test和this_is_test并将其改为一个单词 - test_this_is_test并使用它重定向到另一个网站。



但是网址可能会有所不同，但有类似的模式。所以我不能只搜索this_is_test这个词..



希望它有意义..



谢谢

Hello,

What's a best way to parse a string and find out the particular word.

For instance,

www.abc.com/public/test/this_is_test.php

Now in the above url, I need to find out test and this_is_test and make it into one word - test_this_is_test and use it to redirect to another site.

But the url can vary but with a similar pattern. So I can not just search for the word this_is_test..

Hope it makes sense..

Thanks

推荐答案

string url = "www.abc.com/public/test/this_is_test.php";
string[] splitString = url.Split('/');
var lastValue = string.Empty;
string lastPart = string.Empty;
for(int i = 0; i <splitstring.count;>{
 var secondValue = splitString[2].ToString();
 lastValue = splitString[3].ToString();
}

现在你将在单独的变量中得到test和this_is_test.php。

再次你需要拆分lastValue使用'。'并获得第一部分如下：

Now you will get the test and this_is_test.php in the separate variables.
Again you need to split the lastValue with the '.' and get the first part as below:

string[] lastSplit = lastValue.Split('.');
lastPart = lastSplit[0].ToString();

所以你的最终值将是secondValue和lastpart的连续符号如下：

So your final value will be the concatantion of the secondValue and lastpart as below:

string finalValue = secondValue + "_" + lastPart;

希望它对您有所帮助。

Hope it will be helpful to you.
