Membership.GetUser or Profile.GetProfile?

Whats the different between Membership.GetUser and Profile.GetProfile if i wants to return a specific users information?

Solution

Membership and Profile are two completely different things. The Membership.GetUser providers authentication for an application and designates if the user is logged in, while the Profile is something that can be used to describe a user given properties that have been defined in the web.config that are type safe and customized for an applicaiton.

EDIT: To follow up a little more, a User object that is returned from Membership.GetUser() has information like username, password, security question / answer.

Profile information can contain anything that you want to know about a user, such as first name, last name, DOB, favorite type of ice cream, etc. Just as long as you set this up in the web.config:

<system.web>
    <profile>
        <properties>
            <add name="firstName" type="string"/>
            <add name="lastName" type="string"/>
            <add name="DOB" type="DateTime"/>
            <add name="favoriteIceCream" type="string"/>
        </properties>           
    </profile>
</system.web>
