public class MyCommand : ICommand { public async Task ExecuteAsync() { // code to execute asynchronously } } public class CommandExecutor { private readonly ICommandService _commandService; public CommandExecutor(ICommandService commandService) { _commandService = commandService; } public async Task ExecuteCommand(ICommand command) { await _commandService.ExecuteAsync(command); } }In this example, we create a command object called `MyCommand` which implements the `ICommand` interface with an `ExecuteAsync()` method. We also create a class called `CommandExecutor` which takes an instance of `ICommandService` in its constructor. We then create a method called `ExecuteCommand` which takes an `ICommand` instance and executes it asynchronously using the `ICommandService ExecuteAsync` method. Overall, `ICommandService ExecuteAsync` is a useful tool for executing asynchronous commands in C# applications.
