Freezable::WritePreamble Method
Visual Studio 2010
Namespace:
System.Windows
Assembly: WindowsBase (in WindowsBase.dll)
| Exception | Condition |
|---|---|
| InvalidOperationException | The Freezable instance is frozen and cannot have its members written to. |
This method calls VerifyAccess to verify the threading context is accessible, and it throws an exception if the Freezable instance is already frozen.
Notes to InheritorsClasses that derive from Freezable should call WritePreamble before attempting to write to any members that are not dependency properties. If you call WritePreamble in an API, you can omit a call to ReadPreamble.
Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
