Compiler Warning (level 4) C4434

  • Article

a class constructor must have private accessibility; changing to private access

C4434 indicates that the compiler changed the accessibility of a static constructor. Static constructors must have private accessibility, as they are only meant to be called by the common language runtime. For more information, see Static constructors.

Example

The following sample generates C4434.

// C4434.cpp
// compile with: /W4 /c /clr
public ref struct R {
   static R(){}   // C4434
};
