# What is the using statement in C#? How is it different from IDisposable?

- The `using` statement ensures that resources like file handles, DB connections, etc., are disposed automatically.
- It works on types that implement the `IDisposable` interface.

```cs
using (var reader = new StreamReader("file.txt")) {
    string content = reader.ReadToEnd();
}
```

`IDisposable.Dispose()` is called implicitly at the end of the `using` block.
