RuntimeWrappedException Class

Note: This class is new in the .NET Framework version 2.0.

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

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

[SerializableAttribute] 
public sealed class RuntimeWrappedException : Exception
/** @attribute SerializableAttribute() */ 
public final class RuntimeWrappedException extends Exception
SerializableAttribute 
public final class RuntimeWrappedException extends Exception

Some languages, such as C++, allow you to throw exceptions of any 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 as an exception in C++ and catch it using a RuntimeWrappedException object.

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

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

        Console::WriteLine("String exception thrown.");

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

int main()
{
    run();

    return 0;
}
