Updates information about a user in the SQL Server membership database.(Overrides MembershipProvider.UpdateUser(MembershipUser).)
Verifies that the specified user name and password exist in the SQL Server membership database.(Overrides MembershipProvider.ValidateUser(String, String).)
This class is used by the Membership and MembershipUser classes to provide membership services for an ASP.NET application using a SQL Server database. You cannot use a without SQL Server. When your computer has SQL Server Express installed with the default instance name and user-instancing enabled, the object will create a database called aspnetdb in the application's App_Data directory the first time the application is run.
To manually create the database, run the Aspnet_regsql.exe executable found in the %systemroot%\Microsoft.NET\Framework\ versionNumber folder and specify the -A m option (for example aspnet_regsql.exe -A m). The database created is called Aspnetdb. Alternatively, run Aspnet_regsql.exe to pull up the GUI configuration mode and choose to configure all ASP.NET Features.
If the membership provider is configured with a connection string that uses integrated security, the process account of the ASP.NET application must have rights to connect to the SQL Server database.
The Machine.config file defines a default AspNetSqlMembershipProvider that connects to the default SQL Server Express instance on the local machine. You can use this instance of the provider if you installed SQL Server Express with the default instance name, or you can define your own instance in the Web.config file for your ASP.NET application.instance named
If you set the passwordCompatMode attribute to Framework40, the application can use the hashing and encryption membership options that were added in ASP.NET 4. However, if the passwordCompatMode attribute is set to Framework20, only the hashing and encryption membership options from the ASP.NET 2.0, ASP.NET 3.5, and ASP.NET 3.5 SP1 can be used. The default value is Framework20. For more information, see MembershipPasswordCompatibilityMode.
The following code example shows the Web.config file for an ASP.NET application configured to use a.
<configuration> <connectionStrings> <add name="SqlServices" connectionString="Data Source=localhost;Integrated Security=SSPI;Initial Catalog=aspnetdb;" /> </connectionStrings> <system.web> <authentication mode="Forms" > <forms loginUrl="login.aspx" name=".ASPXFORMSAUTH" /> </authentication> <authorization> <deny users="?" /> </authorization> <membership defaultProvider="SqlProvider" userIsOnlineTimeWindow="15"> <providers> <add name="SqlProvider" type="System.Web.Security.SqlMembershipProvider" connectionStringName="SqlServices" applicationName="MyApplication" enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="true" requiresUniqueEmail="false" passwordFormat="Hashed" maxInvalidPasswordAttempts="5" passwordAttemptWindow="10" /> </providers> </membership> </system.web> </configuration>
