c# - 如何删除我的会员表中的所有用户？

Question

我有一个测试要求删除 SimpleMembershipProvider UserProfile 表中的所有用户。我想在我的 SeedMembership() 方法中执行此操作（如下）。像membership.DeleteAllUsers 这样的东西。知道如何做到这一点吗？

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");

        }

Answer 1

在 SQL Server 和 MySQL 中，您可以运行：

TRUNCATE my_aspnet_users
TRUNCATE my_aspnet_membership
TRUNCATE my_aspnet_profiles
TRUNCATE my_aspnet_roles

或者干脆这样做......

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

好吧，如果您想删除所有成员，请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。

我不得不在几个项目上实现类似的功能，我发现最简单的方法是这样（从记忆中，但我认为这会起作用）：

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);
}
