How to delete user accounts in asp.net?

Question

I have a Register page, I used the following Walkthrough: Creating a Web Site with Membership and User Login to make my webpage. The problem is the Registration page creates users, but I am clueless about how to delete user accounts from the Database where it gets stored.

Answer 1

The membership provider has a DeleteUser method.

The following works just as well:

Membership.DeleteUser("username");

Answer 2

For the completeness' sake, here is a solution similar to Yasser's, however, with using the UserName instead of the GUID as the OP has asked:

DECLARE @UserId uniqueidentifier
SET @UserId = (SELECT TOP(1) UserID FROM aspnet_Users 
  WHERE UserName = 'THE USERNAME OF THE USER HERE')

DELETE FROM aspnet_Profile WHERE UserID = @UserId
DELETE FROM aspnet_UsersInRoles WHERE UserID = @UserId
DELETE FROM aspnet_PersonalizationPerUser WHERE UserID = @UserId
DELETE FROM dbo.aspnet_Membership WHERE UserID = @UserId
DELETE FROM aspnet_users WHERE UserID = @UserId
