Compiler Warning (level 1) C4572


For the latest documentation on Visual Studio 2017 RC, see Visual Studio 2017 RC Documentation.

[ParamArray] attribute is deprecated under /clr, use '...' instead

An obsolete style for specifying a variable argument list was used. When compiling for the CLR, use ellipsis syntax instead of ParamArrayAttribute. For more information, see Variable Argument Lists (...) (C++/CLI).

The following sample generates C4572.

// C4572.cpp  
// compile with: /clr /W1  
void Func([System::ParamArray] array<int> ^);   // C4572  
void Func2(... array<int> ^){}   // OK  
int main() {  
   Func2(1, 2, 3);
