推荐答案

您可以搜索关键字。关键字仍然只是一个单词，您可以在文件内（或在长字符串内）搜索。然后你可以简单地获取文档的内容，你有一个字符串。并在其上执行字符串函数以在其中查找数据。



例如，如果您要查找单词的完全匹配，可以编写此代码，

You can search for a keyword. A keyword is still just a word, that you can search for inside the file (or inside a long string). Then you can simply just get the content of the document, you're having as a string. And perform string functions over it to find your data in it.

For example, if you're going to find an exact match of a word you can write this code,

string data = "This is your data";
string word = "word";

if(data.IndexOf(word) != -1) {
  // The word is found in the string
}

..或者因为IndexOf返回一个整数值，你也可以用字符串的单词得到这个单词的索引。还有很多其他选项，可以在ASP.NET中使用C＃在一串数据中查找单词。

.. or since IndexOf returns an integer value, you can also get the index of this word in the words of string too. Quite multiple other options too, to seach for a word inside a string of data using C# in ASP.NET.
