ASP.NET成员资格密码重置无需符号

Question

我在一个应用程序中使用了asp.net Membership Provider。同时，我也使用了“开箱即用”的asp:PasswordRecovery控件。

我的客户抱怨说新密码太复杂了。例如：}>;-(hYrS^OTfY

有没有什么小的调整可以让新密码只包含字母和数字？

谢谢！

我查了一下，没找到通过 web.config 影响 ResetPassword() 功能的方法。很可能你需要自己创建解决方案来解决这个问题。 - Greg

谢谢 Greg！我将在本周晚些时候发布我从那篇文章中开发的代码。 - aron

这个有效：

    using System;
using System.Collections.Generic;
using System.Web.Profile;
using System.Web.Security;
using System.Text;

namespace TS.Common.MembershipProvider
{
    public class MembershipProvider : SqlMembershipProvider
    {
        /// Create an array of characters to user for password reset.
        /// Exclude confusing or ambiguous characters such as 1 0 l o i
        string[] characters = new string[] { "2", "3", "4", "5", "6", "7", "8",
            "9", "a", "b", "c", "d", "e", "f", "g", "h", "j", "k", "m", "n",
            "p", "q", "r", "s", "t", "u", "v", "w", "x", "y", "z"};

        const int DefaultResetPasswordLength = 10;
        private int ResetPasswordLength;

        // Create a more user friendly password to avoid confusion when
        // trying to key in the new value
        public override string GeneratePassword()
        {
            string newPassword = string.Empty;
            System.Random rnd = new Random();

            for (int i = 0; i < ResetPasswordLength; i++)
            {
                newPassword +=
                characters[rnd.Next(characters.GetUpperBound(0))];
            }
            return newPassword;
        }
    }

}
