i made a dll in C# with Class Library project.
this dll has one function.
then i added this dll in an MFC project with Add Reference.
then i define a variable with type Mydll::Class1.
while this definition is placed in a function, there is no problem but when i want to define it as global or member variable of class i got an error.

the help offers this message:
You can only define CLR objects within function scope

is there any solution to define a global variable?

I doubt you can achieve that in plain vanila way!. See you are trying to export class, which is not possible straight forward.

I See you are MFC programmer, have you heard about MFC extension library these DLL are only capable of exporting class without com support for rest COM is only way. otherwise you wrap you dll and provide plain method to export data
