RuntimeWrappedException Class

Wraps an exception that does not derive from the Exception class. This class cannot be inherited.

System.Object
  System.Exception
    System.Runtime.CompilerServices.RuntimeWrappedException

Namespace:  System.Runtime.CompilerServices
Assembly:  mscorlib (in mscorlib.dll)

[SerializableAttribute]
public sealed class RuntimeWrappedException : Exception

The RuntimeWrappedException type exposes the following members.

  NameDescription
Public propertyDataGets a collection of key/value pairs that provide additional user-defined information about the exception. (Inherited from Exception.)
Public propertyHelpLinkGets or sets a link to the help file associated with this exception. (Inherited from Exception.)
Public propertyHResultGets or sets HRESULT, a coded numerical value that is assigned to a specific exception. (Inherited from Exception.)
Public propertyInnerExceptionGets the Exception instance that caused the current exception. (Inherited from Exception.)
Public propertyMessageGets a message that describes the current exception. (Inherited from Exception.)
Public propertySourceGets or sets the name of the application or the object that causes the error. (Inherited from Exception.)
Public propertyStackTraceGets a string representation of the immediate frames on the call stack. (Inherited from Exception.)
Public propertyTargetSiteGets the method that throws the current exception. (Inherited from Exception.)
Public propertyWrappedExceptionGets the object that was wrapped by the RuntimeWrappedException object.

  NameDescription
Public methodEquals(Object)Determines whether the specified object is equal to the current object. (Inherited from Object.)
Public methodGetBaseExceptionWhen overridden in a derived class, returns the Exception that is the root cause of one or more subsequent exceptions. (Inherited from Exception.)
Public methodGetHashCodeServes as the default hash function. (Inherited from Object.)
Public methodGetObjectDataSets the SerializationInfo object with information about the exception. (Overrides Exception.GetObjectData(SerializationInfo, StreamingContext).)
Public methodGetTypeGets the runtime type of the current instance. (Inherited from Exception.)
Public methodToStringCreates and returns a string representation of the current exception. (Inherited from Exception.)

Some languages, such as C++, allow you to throw exceptions of any managed type. Other languages, such as Microsoft C# and Visual Basic, require that every thrown exception be derived from the Exception class. To maintain compatibility between languages, the common language runtime (CLR) wraps objects that do not derive from Exception in a RuntimeWrappedException object.

You can use the RuntimeCompatibilityAttribute class to specify whether exceptions should appear wrapped inside catch blocks and exception filters for an assembly. Many language compilers, including the Microsoft C# and Visual Basic compilers, apply this attribute by default to specify the wrapping behavior.

Note that the runtime still wraps exceptions even if you use the RuntimeCompatibilityAttribute class to specify that you do not want them wrapped. In this case, exceptions are unwrapped only inside catch blocks or exception filters.

The following code example demonstrates how to throw a String object as an exception in C++ and catch it using a RuntimeWrappedException object.

using namespace System;
using namespace System::Runtime::CompilerServices;

[assembly:RuntimeCompatibilityAttribute(WrapNonExceptionThrows = true)]; 

void run()
{
    try
    {
        throw gcnew String("This is a string");

    }
    catch(RuntimeWrappedException^ e)
    {
        Console::WriteLine("RuntimeWrappedException caught!");
    }
}

int main()
{
    run();

    return 0;
}
