I declare an array in .h file as the following:
 public __gc class myClass
 {
 public:
  int myIntArray __gc[];
。。。

in the class constructor:

myIntArray= __gc new int[5];
for (int i=0;i<2;i++) myIntArray[i]=i;

what I get are compiler errors, as follows:

Lib2.cpp(22) : error C2726: “__gc new”can not create __gc object
Lib2.cpp(22) : error C2440: “=” ....

What is the proper syntax?
Thanks!

Hi CFree,

Just use

public __gc class myClass
 {
 public:
  int myIntArray *__gc;
   // etcetera
}

don't forget to delete your array in the destructor

Good luck,
Jaime.

hi Jaime,
since the array declared as the managed code, why need i delete it in the destructor?
Thanks!

Is your myIntArray class being reconized at that point?
Maybe you have not #included proper header.

public:
  int myIntArray *__gc;

I replaced  " int myIntArray __gc[] " with the above section  in the head file.

Correct syntax is:

    public __gc class myClass
   {
      public:
      int myIntArray __gc[];
    };


then:

    myIntArray= new int __gc[5];
    for (int i=0;i<2;i++) myIntArray[i]=i;
