Its really simple to read a console’s text (contents) in C#. This can be done using the Console.In.ReadLine() method. The Console and the Console.In classes exposes a loads of methods that are really handy. Here is a small snippet that tries to print the directories in blue color and the others in default color in console when you type dir.

string aConsoleReadLine = null;
ConsoleColor aDefaultConsoleColor = Console.ForegroundColor;
while ((aConsoleReadLine = Console.In.ReadLine()) != null)  //Reading the text from the console and storing it in a local variable
{
  if (aConsoleReadLine.Contains("<DIR>"))  //Check if it is a directory
  {
    Console.ForegroundColor = ConsoleColor.Blue;
  }
  else
  {
    Console.ForegroundColor = aDefaultConsoleColor;
  }
  Console.WriteLine(string.Format("{0}", aConsoleReadLine));
}

To run the above mentioned snippet, create a console app and put this snippet in your main method. Then, open up command prompt. In the command prompt type dir | <your_built_exe>.exe. We use | so that we can get the output to our program.

Yeah. One can overload operators in a structure (C#). Syntaxes are similar to that of class operator overloading, except for that fact that we need to operate on struct variables and not on class objects (obvious isn’t it ??).

For newbies — struct is of value type (stored in stacks) and classes are of reference types (stored in heaps)

You can add two Size or Point members directly using the + key. Did you know that ?? You can even do -, == and != on these memebers. You cannot do * or / on them thou’. If  you find anyother class / struct in C# that enables operator overloading, you can add it to the above it. Hope you find this useful.
