## 2. MessageBox

### 2.1 Basic Usage

```csharp
// Simple message
MessageBox.Show("Operation completed successfully.");

// With title
MessageBox.Show("File saved.", "Success");

// With buttons
var result = MessageBox.Show(
    "Do you want to save changes?",
    "Confirm",
    MessageBoxButton.YesNoCancel);

// With icon
MessageBox.Show(
    "An error occurred.",
    "Error",
    MessageBoxButton.OK,
    MessageBoxImage.Error);
```

### 2.2 MessageBox Options

**Buttons:**
| Value | Buttons |
|-------|---------|
| OK | OK |
| OKCancel | OK, Cancel |
| YesNo | Yes, No |
| YesNoCancel | Yes, No, Cancel |

**Icons:**
| Value | Icon |
|-------|------|
| None | No icon |
| Information | Info circle |
| Warning | Warning triangle |
| Error | Red X |

### 2.3 Processing Results

```csharp
var result = MessageBox.Show(
    "Are you sure you want to delete this item?",
    "Confirm Delete",
    MessageBoxButton.YesNo,
    MessageBoxImage.Warning,
    MessageBoxResult.No);  // Default button

switch (result)
{
    case MessageBoxResult.Yes:
        DeleteItem();
        break;
    case MessageBoxResult.No:
        // Cancelled
        break;
}
```
