XamlParseException Class
Represents the exception class for parser-specific exceptions from a WPF XAML parser. This exception is used in XAML API or WPF XAML parser operations from .NET Framework 3.0 and .NET Framework 3.5, or for specific use of the WPF XAML parser by calling System.Windows.Markup.XamlReader API.
Assembly: PresentationFramework (in PresentationFramework.dll)

UidContext | Gets or sets the x:Uid Directive of the object where the exception occurred. |
| Name | Description | |
|---|---|---|
|
|
Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
|
|
Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
|
|
GetBaseException | When overridden in a derived class, returns the Exception that is the root cause of one or more subsequent exceptions. (Inherited from Exception.) |
|
|
GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
|
|
GetObjectData | Gets the data that is required to serialize the specified object by populating the specified SerializationInfo object. (Overrides Exception.GetObjectData(SerializationInfo, StreamingContext).) |
|
|
GetType | Gets the runtime type of the current instance. (Inherited from Exception.) |
|
|
MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
|
|
ToString | Creates and returns a string representation of the current exception. (Inherited from Exception.) |
| Name | Description | |
|---|---|---|
|
SerializeObjectState | Occurs when an exception is serialized to create an exception state object that contains serialized data about the exception. (Inherited from Exception.) |
XamlParseException is used only for the WPF-implemented XAML parser that performs the XAML parsing and loading for WPF applications. Specifically, the exception is only relevant when an application targets .NET Framework 3.0 and .NET Framework 3.5. The exception can also originate from user code in run-time calls to APIs that hook up the WPF-implemented XAML parser to load XAML from within a running WPF application (for example, calls to XamlReader.Load).
For .NET Framework 4, the XamlParseException exception that typically reports XAML processing exceptions is defined in a different namespace (System.Xaml) and a different assembly (System.Xaml).
Unless you are writing an equivalent to the WPF XAML parser or working with .NET Framework 3.0 and .NET Framework 3.5 targeting, you generally will not throw XamlParseException from your own code. However, handling for the exception is sometimes necessary. For application scenarios, where you may want to suppress XAML parse errors, a Dispatcher UnhandledException event handler at the application level is one way to handle a run-time XamlParseException. Whether to suppress exceptions or let them surface to user code depends on how you design your application for purposes of loading XAML, and the trust level that you assign to the XAML your application loads. For more information, see XAML Security Considerations or "XAML Security" section of XAML Overview (WPF).
For pages of an application, when the XamlParseException is thrown, it is usually in the context of the InitializeComponent call made by your page class, which is the entry point for the WPF application model's usage of the WPF XAML parser at the per-page level. Therefore another possible handling strategy is to place try/catch blocks in InitializeComponent. However, this technique does not integrate well with templates, visual design surfaces and other generated sources that hook up InitializeComponent.
