Add FBA users to sharepoint programmatically

Scenario:
You want to add FBA users to one of the SharePoint Group

Solution:
1) Create FBA Membership User
2) Create SharePoint User
3) Get your site instance
4) Add SharePoint User to a Desired group

Code:


MembershipUser membershipUser = Membership.CreateUser(login, password, email);

SPWeb spWeb = SPControl.GetContextWeb(HttpContext.Current);

SPUser spUser = spWeb.EnsureUser(login);
SPGroup spGroup = spWeb.SiteGroups["VISITORS"];
spGroup.AddUser(spUser);

Possible Errors:
[SPException: The user does not exist or is not unique.]
or 
When You try to put this new user into a sp group, the web is redirected to the login page

Use SPSecurity.RunwithElevatedPrivileges and also while giving permission add the MembershipProvider with ":" separated User name

how to do this if i am running the above code from a console app.

what if the above code is put in a console app and run. Will ensureuser will work there as currently is throwing error "User doesnot exists". FYI I am using the using statement to get the SPSite object.

hmm.. I will try on my end over weekend but as long as you were able to create a SPSite object , the code should work.

Doesnt worked for me. Can You post real working example in console Application? I tried so:

SPSecurity.RunWithElevatedPrivileges(delegate()
{
using (SPSite site = new SPSite("http://localhost/"))
using (SPWeb spWeb = site.OpenWeb())
{

try
{
MembershipUser membershipUser = Membership.CreateUser(login, password);

// fba_member is providr from web.config, but it doesn't help
SPUser spUser = spWeb.EnsureUser("fba_member:" + login);
SPGroup spGroup = spWeb.SiteGroups["FBA_Users"];
spGroup.AddUser(spUser);
}
catch (Exception ex)
{
System.Console.WriteLine(ex.ToString());
}
}
});

This is a working example. I usually only code from my projects.

But I will take a look over weekend.
Also you can try adding a FBA user first from Sharepoint UI , and then note the format { membershipprovidername:username } , usually that causes issue.

Sandeep K Nahta, thank You for Your response!

I mean working with real values of user, membership provider, etc..

I'm getting an error in translate it will be like "password-answer is invalid"

If You mean solution from codeplex as sharepoint UI, I can't install it on this server. So I wanted to create simple console application to add one User to my FBA.

Sandeep K Nahta, thanks! It works if we add to our console project app.config file with connectionstring and membership and role providers. ;)

I am trying to set up a user self-registration process for a SharePoint site using Forms/Claims Authentication.

The process is, however failing at the line:

SPUser spUser = spWeb.EnsureUser(login);

Where I am re-directed to the login screen.

This appears to be due to the fact that during registration no user is not logged in - i.e. the site context is anonymous and that the process does not have sufficient authority to make user changes.
