How to avoid C# console applications from closing automatically.

• One way is to interop it with msvcrt.dll
  You can pinvoke this C function into your C# application. This process is very easy. There are a few steps:

  1) Insert System.Runtime.InteropServices to your using clauses.
  2) Insert this line in your class (usually in the first few lines)

  [DllImport("msvcrt.dll")]
  static extern bool system(string str);

  3) In that same class, simply write this:

  system("pause");

• The simplest way that I always use is to ask for input

  Console.ReadLine();

  or

  Console.ReadKey();

  ReadLine() waits for ↩, ReadKey() waits for any key (except for modifier keys).
