How to use a DLL

Question

Hi I'm starting with c# now and have previouse used VB6.0. In VB I have declared the following: Declare Function Logon Lib DBCOM (ByVal id As String ByVal TypeNo As Integer ByVal NoOfArg As Integer ArgFields As Integer ArgValues As String) As Integer I then call the function Logon in the code to access the logon function in the DBCOM.DLL. The code goes like this: Dim iReturnVal as integer iReturnVal = Logon(User1343The args) I hope there is some smart C# brains in this forum who can help me by telling me how I can use this Logon function placed in the DBCOM.DLL from C#. Thanks
