### 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 uses the collection's synchronization root while reading its size.

```csharp
ICollection collection = textControl.SubTextParts;
lock (collection.SyncRoot)
{
    Console.WriteLine($"Named regions: {collection.Count}");
}
```

```vbnet
Dim collection As ICollection = textControl.SubTextParts
SyncLock collection.SyncRoot
    Console.WriteLine($"Named regions: {collection.Count}")
End SyncLock
```

### Limitations

Read only.
