Compiler Error C2715

'type' : cannot throw or catch this type

Remarks

Value types are not valid arguments when using exception handling in managed code (see Exception Handling for more information).

Example

The following example generates C2715 and shows how to fix it:

// C2715a.cpp
// compile with: /clr
using namespace System;

value struct V {
   int i;
};

void f1() {
   V v;
   v.i = 10;
   throw v;   // C2715
   // try the following line instead
   // throw ((V^)v);
}

int main() {
   try {
      f1();
   }

   catch(V v) { if ( v.i == 10 ) {   // C2715
   // try the following line instead
   // catch(V^ pv) { if ( pv->i == 10 ) {
         Console::WriteLine("caught 10 - looks OK");
      }
      else {
         Console::WriteLine("catch looks bad");
      }
   }
   catch(...) {
      Console::WriteLine("catch looks REALLY bad");
   }
}
