# SheetProtection
```csharp
public sealed class SheetProtection
```
Namespace `SharpCell` ยท package `SharpCell`
What users may still do on a protected sheet, as Excel's Protect Sheet dialog lists it: by default they may select cells and nothing else. Set properties in an initializer and pass the object to [Worksheet.Protect](SharpCell.Worksheet.md#protect-string-sheetprotection). Excel enforces the protection; SharpCell only keeps and saves it.
## Constructors
### SheetProtection()
```csharp
public SheetProtection()
```
A protection allowing users to select cells and nothing else; set properties in an initializer.
### SheetProtection(SheetProtection)
```csharp
public SheetProtection(SheetProtection source)
```
A copy of another protection, so it can be changed in an initializer: `new SheetProtection(sheet.Protection) { Sort = true }`.
**Parameters**
- `source`: The protection to copy.
**Exceptions**
- `ArgumentNullException`: The source is null.
