Correct convert/marshall C Function and DLL Structure type to C#

Question

Hi,

Can someone please help me convert my C structure/function into C#? I really need this badly...

I believe I can call the DLL properly if I have able to correctly convert the function and marshal properly my structure.

Here is my struct and the function that uses it:

[CODE]

typedef struct UIclient_info {

char name[50];

int age;

SECONDUSER *stParent;

} FIRSTUSER;

typedef struct ui_product_form {

char m_sCoupon;

double amountTotal;

char m_sErrorCode[50];

SUBPRODUCT *pstSubProduct;

} PRODUCT;

typedef struct tagReport

{

REPORTSUMMARY *pstRepsum;

char errorMsg[100];

}FINAL_REPORT;

int Save(FIRSTUSER *myUser, PRODUCT *uiStructure)

FINAL_REPORT GenerateReport(FIRSTUSER *myUser, PRODUCT *uiStructure)

[/CODE]

PLEASE HELP.

Thanks in advance.
