] | How do I make the computer's internal speaker beep in C# without external speakers? | In .Net 2.0, you can use [`Console.Beep`](https://learn.microsoft.com/en-us/dotnet/api/system.console.beep).
```
// Default beep
Console.Beep();
```
You can also specify the frequency and length of the beep in milliseconds.
```
// Beep at 5000 Hz for 1 second
Console.Beep(5000, 1000);
