Just wanted to understand what is the best possible way to extract a SPUser object using Login Name in string format.
I was using this till now:SPFieldUserValue spfUser = new SPFieldUserValue(spWeb, "<login name>");
SPUser oUser = spfUser.User;
Now, the 1st line fails with an exception "Value out of range" for a user who has READ through Visitor´s group and CONTRIBUTE through Member´s.
So, I changed to this:
SPUser oUser = spWeb.EnsureUser("<login name>");
THis works perferctly fine.
But what´s the problem with the 1st one? And any negative impact due to the 2nd option? And, is there any other better way to do this?
With first approach you mentioned, you will get an error if the user has never browsed the site (ie., there wont be ay entry for this user in the user information list)
When you use EnsureUser() method, it checks if the user details are present in the user information list. If not, it will add them.
So, it a good to use EnsureUser() method.

Thanks Ram, but that´s what is confusing me.
The user (that is throwing the error) is using the site and in fact this error is thrown when the user is doing an action that has these lines in it´s code behind.
I had cross checked, this person is there in the UserInfoList.
maybe the user don't have the right to see the user "login name" , where is the "login name" user define? is it in a group that the current user can see the members?
