RuntimeWrappedException Class

Definition

Namespace:

System.Runtime.CompilerServices

Assembly:

System.Runtime.dll

Source:

RuntimeWrappedException.cs

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

public ref class RuntimeWrappedException sealed : Exception

public sealed class RuntimeWrappedException : Exception

type RuntimeWrappedException = class
    inherit Exception

Public NotInheritable Class RuntimeWrappedException
Inherits Exception

Inheritance

RuntimeWrappedException

Examples

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;
}

Remarks

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.

Constructors

RuntimeWrappedException(Object)

Initializes a new instance of the RuntimeWrappedException that contains the inner exception object.

Properties

Data	Gets a collection of key/value pairs that provide additional user-defined information about the exception. (Inherited from Exception)
HelpLink	Gets or sets a link to the help file associated with this exception. (Inherited from Exception)
HResult	Gets or sets HRESULT, a coded numerical value that is assigned to a specific exception. (Inherited from Exception)
InnerException	Gets the Exception instance that caused the current exception. (Inherited from Exception)
Message	Gets a message that describes the current exception. (Inherited from Exception)
Source	Gets or sets the name of the application or the object that causes the error. (Inherited from Exception)
StackTrace	Gets a string representation of the immediate frames on the call stack. (Inherited from Exception)
TargetSite	Gets the method that throws the current exception. (Inherited from Exception)
WrappedException	Gets the object that was wrapped by the RuntimeWrappedException object.

Methods

Equals(Object)	Determines whether the specified object is equal to the current object. (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 the default hash function. (Inherited from Object)
GetObjectData(SerializationInfo, StreamingContext)	Obsolete. Sets the SerializationInfo object with information about the exception.
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)

Events

SerializeObjectState

Obsolete. Occurs when an exception is serialized to create an exception state object that contains serialized data about the exception. (Inherited from Exception)
