| The function declaration :
public static extern Int32 WNetAddConnection2(
ref NETRESOURCE
lpNetResource,
[MarshalAs(UnmanagedType.LPStr)] string lpPassword,
[MarshalAs(UnmanagedType.LPStr)] string lpUserName,
Int32 dwFlags);
Says the parameter must be passed by reference. You need to call this function like:
WNetAddConnection2(ref theNetResource, ........
Give that a try
