    <p>I am currently doing a small C# exercise that deals with searching related terms/words in an text file and the program will write out all sentences in the text file that include the searched word. For instance, I enter the word: "example", and what the program will do is go through all the sentences in a text file and pull out those sentences that have the word "example" in them. </p> <pre><code>The text file is structured as so: &lt;sentenceDesignator&gt; &lt;text&gt; sentence 1: bla bla bla bla example of a sentence //each line contains a sentence sentence 2: this is not a good example of grammar sentence 3: bla is not a real word, use better terms </code></pre> <p>What I would like to be able to do is use a linear search to go through all the lines in the text file and write out all sentences that contain the searched string term.</p> <p>My code so far:</p> <pre><code> String filename = @"sentences.txt"; if (!File.Exists(filename)) { // Since we just created the file, this shouldn't happen. Console.WriteLine("{0} not found", filename); return; } else { Console.WriteLine("Successfully found {0}.", filename); } //making a listof type "Sentence" to hold all the sentences List&lt;Sentence&gt; sentences = new List&lt;Sentence&gt;(); //the next lines of code... StreamReader reader = File.OpenText(filename); //first, write out all of the sentences in the text file //read a line(sentence) from a line in the text file string line = reader.ReadLine(); while (line != null) { Sentence s = new Sentence(); //we need something to split data... string[] lineArray = line.Split(':'); s.sentenceDesignator = lineArray[0]; s.Text = lineArray[1]; Console.Write("\n{0}", line); line = reader.ReadLine(); } //so far, we can write out all of the sentences in the text file. Console.Write("\n\nOK!, search a term to diplay all their occurences: "); string searchTerm = Console.ReadLine(); if(!line.Contains(searchterm)) { Console.Write("\nThat term does not exist in any sentence."); } else { foreach (Sentence ss in sentences) { if (ss.sentenceDesignator.Contains(queryName)) { //I need help here } } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
