C# 允许RequireUniqueEmail=false会导致ChangePasswordAsync方法出错

在我的c#代码中，我允许接受具有以下代码的相同电子邮件的用户

UserValidator = new UserValidator<ApplicationUser>(this)
    {
        AllowOnlyAlphanumericUserNames = false,
        RequireUniqueEmail = false
    };

---

我现在应该在哪里进行更改，这样就可以了？？？

您是否将电子邮件地址视为用户名？如果是，则为用户提供唯一的用户名，但允许使用相同的电子邮件地址

还可以在web.config中查看RequireSuiQueeMail标记

    <membership defaultProvider="MySqlMembershipProvider">
      <providers>
        <clear />
        <add connectionStringName="SimpleConnection" applicationName="abc" enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="false" requiresUniqueEmail="false" passwordFormat="Hashed" maxInvalidPasswordAttempts="15" minRequiredPasswordLength="7" minRequiredNonalphanumericCharacters="0" passwordAttemptWindow="10" passwordStrengthRegularExpression="" name="MySqlMembershipProvider" type="System.Web.Security.SqlMembershipProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
      </providers>
    </membership>
