How to Keep a C# Console Application Open After Execution?

Prevent C# Console Apps from Immediately Closing

During C# console application development within Visual Studio, it's beneficial to retain the console window after execution to review the output. By default, the console closes automatically; however, several methods prevent this:

Visual Studio Setting (2017 and later):

The simplest approach, available in newer Visual Studio versions, involves a configuration setting:

1. Access the Visual Studio settings via Tools → Options.
2. Navigate to the Debugging tab.
3. Deactivate the checkbox labeled "Automatically close the console when debugging stops."

Manual Code Implementation:

For older Visual Studio versions or those preferring a code-based solution, these methods pause execution:

• Console.ReadLine(): This function waits for a user to press Enter before proceeding.

  <code class="language-csharp"> Console.ReadLine();</code>

• Console.ReadKey(): This function waits for any keypress (excluding modifier keys like Shift or Ctrl).

  <code class="language-csharp"> Console.ReadKey();</code>

Example:

The following code snippet illustrates the Console.ReadKey() method:

<code class="language-csharp">Console.WriteLine("Hello World!");

// Pause execution until a key is pressed
Console.ReadKey();</code>

This enhanced example displays "Hello World!" and then pauses, allowing output inspection before closing.
