MissingInteropDataException Class (.NET Native)
.NET for Windows apps for Windows 10, .NET Native only
The exception that is thrown when a manual marshaling method is called, but metadata for a type isn't found by static analysis or in a runtime directives file.
Namespace: System.Runtime.CompilerServices
Important
The MissingInteropDataException class is intended solely for internal use by the .NET Native tool chain. It is not intended for use in third-party code, nor should you handle the exception in your application code. Instead, you eliminate the exception by adding entries to your runtime directives file. For more information, see the Remarks section.
Syntax
public class MissingInteropDataException : Exception
The MissingInteropDataException class has the following members:
Constructors
| Constructor | Description |
|---|---|
public MissingInteropDataException(String resourceId, Type pertinentType) |
Initializes a new instance of the MissingInteropDataException class by using the ID of a system-supplied message that describes the error and the type whose data is missing. This constructor is for internal use by the .NET Native tool chain only. |
Properties
| Property | Description |
|---|---|
public IDictionary Data { get; } |
Gets a collection of key/value pairs that provide additional user-defined information about the exception. (Inherited from System.Exception.) |
public string HelpLink { get; set; } |
Gets or sets a link to the help file associated with this exception. (Inherited from System.Exception.) |
public int HResult { get; protected set; } |
Gets or sets the HRESULT, which is a coded numeric value that is assigned to a specific exception. (Inherited from System.Exception.) |
public Exception InnerException { get; } |
Gets the exception that caused the current exception. (Inherited from System.Exception.) |
public string Message { get; } |
Gets a message that describes the current exception. (Inherited from System.Exception.) |
public Type MissingType { get; private set; } |
Gets or sets the type whose data is missing. |
public string Source { get; set; } |
Gets or sets the name of the app or object that caused the error. (Inherited from System.Exception.) |
public string StackTrace { get; } |
Gets a string representation of the immediate frames on the call stack. (Inherited from System.Exception.) |
public MethodBase TargetSite { get; } |
Gets the method that threw the current exception. (Inherited from System.Exception.) |
Methods
| Method | Description |
|---|---|
public bool Equals(Object obj) |
Determines whether the specified object is equal to the current object. (Inherited from Object.) |
protected void Finalize() |
Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
public Exception GetBaseException() |
Returns the exception that is the root cause of one or more subsequent exceptions. (Inherited from System.Exception.) |
public int GetHashCode() |
Returns a hash code for a MissingInteropDataException instance. (Inherited from Object.) |
public void GetObjectData(SerializationInfo info, StreamingContext context) |
Sets a SerializationInfo object with information about the exception. (Inherited from System.Exception.) |
public Type GetType() |
Gets the runtime type of the current instance. (Inherited from System.Exception.) |
protected Object MemberwiseClone() |
Creates a shallow copy of the current object. (Inherited from Object.) |
public string ToString() |
Returns the string representation of the current exception. (Inherited from System.Exception.) |
Events
| Event | Description |
|---|---|
protected event EventHandler<SafeSerializationEventArgs> SerializeObjectState |
Occurs when an exception is serialized to create an exception state object that contains serialized data about the exception. (Inherited from System.Exception.) |
Usage Details
The MissingInteropDataException exception is thrown when a method call to a COM or Windows Runtime component cannot be made successfully because type information isn't available.
The metadata that is available to an app at run time is defined by the runtime directives (XML configuration) file, *.rd.xml. To prevent your app from throwing this exception, you must modify this file to define the metadata that must be present at run time. Most commonly, you address this error by adding a MarshalObject, MarshalDelegate, or MarshalStructure attribute to an appropriate program element in the runtime directives file. For information about the format of this file, see Runtime Directives (rd.xml) Configuration File Reference.
Important
Because this exception indicates that metadata needed by your application isn't available at run time, you shouldn't handle this exception in a try/catch block. Instead, you should diagnose the cause of the exception and eliminate it by adding the appropriate entry to a runtime directives file.
The MissingInteropDataException class contains a single unique member, the MissingType property, that indicates the type whose metadata is needed for a successful method call. All remaining members are inherited from the base class, System.Exception.
