# How to: Obtain a Writable Copy of a Read-Only Freezable
|
|
This example shows how to use the <xref:System.Windows.Freezable.Clone%2A> method to create a writable copy of a read-only <xref:System.Windows.Freezable>.
|
|
|
|
After a <xref:System.Windows.Freezable> object is marked as read-only ("frozen"), you cannot modify it. However, you can use the <xref:System.Windows.Freezable.Clone%2A> method to create a modifiable clone of the frozen object.
|
|
|
|
## Example
|
|
The following example creates a modifiable clone of a frozen <xref:System.Windows.Media.SolidColorBrush> object.
