Compiler Error C3893
'var' : l-value use of initonly data member is only allowed in an instance constructor of class 'type_name'
Static initonly data members can only have their address taken in a static constructor.
Instance (non-static) initonly data members can only have their address taken in instance (non-static) constructors.
The following sample generates C3893:
// C3893.cpp
// compile with: /clr
ref struct Y1 {
Y1() : data_var(0) {
int% i = data_var; // OK
}
initonly int data_var;
};
int main(){
Y1^ y= gcnew Y1;
int% i = y->data_var; // C3893
}
