Wifi Network Backup Manager Utility

After couple of years I was too lazy to do it, each time I format my computer or want to copy Wifi networks between my machine to another I faced a problem, there is easy way to copy network profiles so I’ve created a simple utility that allows you to Save and Load Wifi Network Profiles, using Native Wifi API through P/Invoke interop.

[DllImport("wlanapi.dll")]

public static extern int WlanGetProfile(

[In] IntPtr clientHandle,

[In, MarshalAs(UnmanagedType.LPStruct)] Guid interfaceGuid,

[In, MarshalAs(UnmanagedType.LPWStr)] string profileName,

[In] IntPtr pReserved,

[Out] out IntPtr profileXml,

[Out, Optional] out WlanProfileFlags flags,

[Out, Optional] out WlanAccess grantedAccess);

[DllImport("wlanapi.dll")]

public static extern int WlanGetProfileList(

[In] IntPtr clientHandle,

[In, MarshalAs(UnmanagedType.LPStruct)] Guid interfaceGuid,

[In] IntPtr pReserved,

[Out] out IntPtr profileList

);
