endThe RuntimeCompatibilityAttribute type exposes the following members.
| Name | Description | |
|---|---|---|
.gif) | RuntimeCompatibilityAttribute | Initializes a new instance of the RuntimeCompatibilityAttribute class. |
| Name | Description | |
|---|---|---|
.gif) | TypeId | When implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute.) |
| WrapNonExceptionThrows | Gets or sets a value that indicates whether to wrap exceptions that do not derive from the Exception class with a RuntimeWrappedException object. |
| Name | Description | |
|---|---|---|
| Equals | Infrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.) |
.gif) | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
| GetHashCode | Returns the hash code for this instance. (Inherited from Attribute.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| IsDefaultAttribute | When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.) |
| Match | When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
| Name | Description | |
|---|---|---|
.gif) .gif) | _Attribute | Maps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.) |
| _Attribute | Retrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.) |
| _Attribute | Retrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.) |
| _Attribute | Provides access to properties and methods exposed by an object. (Inherited from Attribute.) |
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 apply the RuntimeCompatibilityAttribute class to an assembly that throws a String object as an exception in C++ and catches 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;
}
