why i can't put struct to Generic::List

[shengmin.ruan]

the wrong code is:

[StructLayout(LayoutKind::Sequential)]
public ref struct OutPacket{
int index;
List<MainInfo^>^ mainInfos;
};

[StructLayout(LayoutKind::Sequential)]
public ref struct MainInfo{
String^ value1;
String^ value2;
};

----------
the error message is:
Error 1 error C2065: 'MainInfo' : undeclared identifier
please help me ,thank u

public ref struct OutPacket{
int index;
List<MainInfo^>^ mainInfos;
};

[StructLayout(LayoutKind::Sequential)]
public ref struct MainInfo{
String^ value1;
String^ value2;
};

the error message is:
Error 1 error C2065: 'MainInfo' : undeclared identifier

Try swapping the declarations. When you declare OutPacket, MainInfo is still
unknown because its declaration is placed after the declaration to
OutPacket.
Declaring MainInfo first takes care of that problem.
