### Description

Gets an object that can be used to synchronize access to the collection.

### Syntax

The type implements this member of System.Collections.ICollection explicitly: code reaches it by casting to the interface, as in ((ICollection)value).SyncRoot.

```csharp
object ICollection.SyncRoot { get; }
```

```vbnet
Private ReadOnly Property SyncRoot As Object Implements ICollection.SyncRoot
```

### Examples

The following example works with editable regions in the current document by using `EditableRegionCollection.syncroot`.

```csharp
textControl.Text = "Customer: Contoso Ltd.";
textControl.Select(10, 12);
EditableRegionCollection editableRegionCollection = textControl.EditableRegions;
editableRegionCollection.Add(new EditableRegion("ReviewTeam", 100));

ICollection collection = editableRegionCollection;
var value = collection.SyncRoot;
```

```vbnet
textControl.Text = "Customer: Contoso Ltd."
textControl.Select(10, 12)
Dim editableRegionCollection As EditableRegionCollection = textControl.EditableRegions
editableRegionCollection.Add(New EditableRegion("ReviewTeam", 100))

Dim collection As ICollection = editableRegionCollection
Dim value = collection.SyncRoot
```

### Limitations

Read only.
