Recursively searching directories to find text within files in C#

A straightforward utility to recursively search for text contained within files and directories. I created a C# console application. The actual recursive routine to search the directories and subdirectories recursively is quite straightforward: [code language="csharp"] foreach (var directory in Directory.GetDirectories(sDir)) { foreach (var filename in Directory.GetFiles(directory)) { using (var streamReader = new StreamReader(filename)) { var contents = streamReader.ReadToEnd().ToLower(); if (contents.Contains(SearchText)) { FilesFound.Add(filename); } } } DirSearch(directory); } [/code] Each directory is recursively searches as well as all the files contained within it. Full code listing [code language="csharp"] using System; using System.Collections.Generic; using System.IO; using System.Linq; using System.Text; using System.Threading.Tasks; namespace RecursiveSearch { internal class Program { private static List<string> FilesFound { get; } = new List<string>(); private const string SearchText = "get; set;"; private static void DirSearch(string sDir) { try { foreach (var directory in Directory.GetDirectories(sDir)) { foreach (var filename in Directory.GetFiles(directory)) { using (var streamReader = new StreamReader(filename)) { var contents = streamReader.ReadToEnd().ToLower(); if (contents.Contains(SearchText)) { FilesFound.Add(filename); } } } DirSearch(directory); } } catch (System.Exception ex) { Console.WriteLine(ex.Message); } } private static void Main(string[] args) { DirSearch(@"E:\CodeSamples\Archive"); Console.WriteLine("Files containing the word " + SearchText); Console.WriteLine(); foreach (var file in FilesFound) { Console.WriteLine(file); } } } } [/code] So to search for all files containing the text "get; set" within the directory "E:\CodeSamples\Archive" gives the following output: recursivesearch

Using the Supervisor Controller Pattern to access View controls in MVVM

As discussed on a StackOverflow post , this is considered bad practice, so only use this when necessary. Step 1: Create a new WPF project Step 2: Add event handling code A number of classes are needed for doing command bindings in MVVM. Create the following classes and add to your Visual Studio project: RelayCommand.cs [code language="csharp"] using System; using System.Windows.Input; namespace SupervisorControllingPattern { public class RelayCommand<T> : ICommand { private readonly Predicate<T> _canExecute; private readonly Action<T> _execute; public RelayCommand(Action<T> execute) : this(execute, null) { _execute = execute; } public RelayCommand(Action<T> execute, Predicate<T> canExecute) { if (execute == null) throw new ArgumentNullException(nameof(execute)); _execute = execute; _canExecute = canExecute; ...

Getting started with client-server applications in C++

Image
A demonstration of simple Internet client-server applications in C++ (Linux-based). The client application tries to connect to the remote server application using the IP address of the remote server ('localhost' or 127.0.0.1) and the server port number which defaulted to 1234. The server application listens to port number 1234 for a connection request. When the server application receives the connection request it sends the text message "Hello!\r\n" to the client.

How to send an e-mail via Google SMTP using C#

First things first, some useful StackOverflow links: https://stackoverflow.com/questions/9201239/send-e-mail-via-smtp-using-c-sharp https://stackoverflow.com/questions/17462628/the-server-response-was-5-7-0-must-issue-a-starttls-command-first-i16sm1806350 To demonstrate how this is done I first create a new Visual Studio project: Some example code for sending an email via a Google email account (smtp.goolgle.com) - obviously replace this with email / credentials of your own... I put the code within a try-catch block in order to capture any errors that may occur while attempting this. [code language="csharp"] using System; using System.Net; using System.Net.Mail; namespace EmailSmtp { class Program { static void Main(string[] args) { try { // Credentials var credentials = new NetworkCredential("someEmail@gmail.com", "somePassword"); // Mail message var ...
