如何删除我的成员表中的所有用户

我有一个测试，需要删除我的SimpleMembershipProvider UserProfile表中的所有用户。我想在我的SeedMembership()方法(下面)中做到这一点。比如membership。deleteallusers。知道怎么做吗?

private int SeedMembership()
        {
            if (!WebMatrix.WebData.WebSecurity.Initialized)
            {
                WebSecurity.InitializeDatabaseConnection("TestConnection", "UserProfile", "UserId", "UserName", autoCreateTables: true);
            }

            var roles = (SimpleRoleProvider)Roles.Provider;
            var membership = (SimpleMembershipProvider)Membership.Provider;
            if (!roles.RoleExists("Admin"))
            {
                roles.CreateRole("Admin");
            }
            if (!roles.RoleExists("User"))
            {
                roles.CreateRole("User");
            }
            // Somehow delete all users here
            if (membership.GetUser("user", false) == null)
            {
                membership.CreateUserAndAccount("user", "covert");
            }
            if (!roles.GetRolesForUser("user").Contains("Admin"))
            {
                roles.AddUsersToRoles(new[] { "user" }, new[] { "admin" });
            }
            return membership.GetUserId("user");
        }

或者直接这样做…

foreach (MembershipUser u in Membership.GetAllUsers())
{
 Membership.DeleteUser(u.UserName, true);
}

在SQL Server和MySQL中可以运行:

TRUNCATE my_aspnet_users
TRUNCATE my_aspnet_membership
TRUNCATE my_aspnet_profiles
TRUNCATE my_aspnet_roles

我不得不在几个项目中实现类似的功能，我发现最简单的方法是这样做(从记忆中，但我认为这是要工作的):

var dbUsernames = context.Database.SqlQuery<string>("SELECT UserName FROM UserProfile");
foreach (string dbUsername in dbUsernames)
{
    string[] userRoles = Roles.GetRolesForUser(dbUsername);
    if (userRoles != null && userRoles.Length > 0)
    {
        Roles.RemoveUserFromRoles(dbUsername, userRoles); 
    }
    int userId = context.Database.SqlQuery<int>("SELECT UserId FROM UserProfile WHERE UserName = {0}", dbUsername).First();
    // HERE: Delete any other dependent rows in other tables that use UserId, and have referential integrity
    // Now tear down any final bits and delete the user, for example: 
    Membership.DeleteUser(dbUsername, true);
    context.Database.ExecuteSqlCommand(
        "DELETE FROM webpages_Membership WHERE UserId = {0}", userId);
}

如果你想删除所有成员，删除表并重新创建它，这更像是一个技巧而不是答案。或者使用实体框架更容易。
