Using a structure defined (unmanaged code) in a managed code.

[sgunnala]

Hello,

i want to use the unmanaged code in CSharp.

the structure defined in the cpp dll is

typedef struct XTRAP_CLIENT_LI ST
{
char prnNetAdd[100];
char hostAddress[100];
XTYPE_ADDESS ClientType;
struct XTRAP_CLIENT_LI ST* next;
} XTRAP_CLIENT_LI ST;

typedef XTRAP_CLIENT_LI ST FAR * LPXTRAP_CLIENT_ LIST;

how to define this structure in c# .net. and how to use the function which is using the structure.

i have defined the structure as

public struct XTRAP_CLIENT_LI ST
{
[MarshalAs(Unman agedType.ByValT Str, SizeConst = 100)]
public string prnNetAdd;

[MarshalAs(Unman agedType.ByValT Str, SizeConst = 100)]
public string hostAddress;
public XTYPE_ADDESS ClientType;
public IntPtr next;

}

But i don't know how to use use the IntPtr in my function.

Try like this,

IntPtr handle = this.ServiceHan dle;

myServiceStatus .currentState = (int)State.SERV ICE_START_PENDI NG; //0x00000002
myServiceStatus .checkPoint = 1;
myServiceStatus .waitHint = 5000;
SetServiceStatu s(handle, ref myServiceStatus );
