<exception> (Visual C++)

The <exception> tag lets you specify which exceptions can be thrown. This tag is applied to a method definition.

<exception cref="member">description</exception>

member

A reference to an exception that is available from the current compilation environment. Using name lookup rules, the compiler checks that the given exception exists, and translates member to the canonical element name in the output XML. The compiler issues a warning if it does not find member.

Enclose the name in single or double quotation marks.

For information on how to create a cref reference to a generic type, see <see> (Visual C++).

description

A description.

Compile with /doc to process documentation comments to a file.

The Visual C++ compiler will attempt to resolve cref references in one pass through the documentation comments. Therefore, if using the C++ lookup rules, a symbol is not found by the compiler the reference will be marked as unresolved. See <seealso> (Visual C++) for more information.

// xml_exception_tag.cpp
// compile with: /clr /doc /LD
// post-build command: xdcmake xml_exception_tag.dll
using namespace System;

/// Text for class EClass.
public ref class EClass : public Exception {
   // class definition ...
};

/// <exception cref="System.Exception">Thrown when... .</exception>
public ref class TestClass {
   void Test() {
      try {
      }
      catch(EClass^) {
      }
   }
};
