Hi Team，

我需要在.net框架中实现url解析器。当输入网址时，应用程序应显示给定网址中的图像数量，单词数量和最常用的单词。

推荐答案

首先，使用
System.Net.WebClient .DownloadFile（）或.DownloadString下载内容。

First, you use System.Net.WebClient.DownloadFile() or .DownloadString to download the content.

To计算图像的数量，计算"< img"的出现次数。

RegEx.Matches（）。

To count the number of images, count the occurance of "<img" with RegEx.Matches().

要计算字符数，请在''上使用String.Split（）和RemoveEmptyEntries。您可能希望添加一些String.Replace（）以替换某些符号  with space（例如，"，"，"to"""）以确保它被正确地标记化。然后 返回
结果数组的长度。

To count the number of characters, use String.Split() on ' ' with RemoveEmptyEntries. You may want to add some String.Replace() to replace certain symbol with space (say, "," to " ") to ensure it's properly tokenized. And then return the length of resulting array.

要找到最常用的单词，我将循环使用之前生成的标记化数组，并使用Dictionary< string，int>存储每个单词的出现。最后使用.Select（x => x.Value）.Max（）来获取最大出现次数，并输出
字典中的所有单词，其匹配计数如下：

To found the most used word, I'd loop against the previously generated tokenized array, and use a Dictionary<string, int> to store occurance of each word. Finally use .Select(x => x.Value).Max() to get the max occurance count, and output all word within the Dictionary with the matching count with something like:

int maxcnt = result.Select(x => x.Value).Max();
foreach (string word in result.Where(x => x.Value == maxcnt).Select(y => y.Key))
{
     Console.WriteLine(word);
}
//or the following to store the result directly in array:
string[] maxOccWords = result.Where(x => x.Value == maxcnt).Select(y => y.Key).ToArray();

替换Console.WriteLine（），带有用于存储结果的语句。

Replace Console.WriteLine() with statement to store the outcome.
