What are some basic examples of async programming in C#?

Async programming in C# allows you to run tasks without blocking the main thread. A basic example is using async and await keywords.

Can you show me a simple code example?

Sure! Here's a simple example:

public async Task<string> GetDataAsync() {
    await Task.Delay(1000); // Simulates a delay
    return "Data retrieved!";
}

What does Task.Delay do in this context?

Task.Delay creates a task that completes after a specified time, simulating an asynchronous operation like fetching data.

How can I handle exceptions in async methods?

You can use try-catch blocks within your async methods to handle exceptions. For example:

try {
    var data = await GetDataAsync();
} catch (Exception ex) {
    // Handle exception
}
