以下C＃示例代码演示了如何通过Jacques L. Chereau以 编程方式配置.NET成员资格提供程序 。 此代码要求您还配置名为MyDatabase 的连接字符串

 NameValueCollection objConfig = new NameValueCollection(); objConfig.Add("connectionStringName", "MyDatabase"); objConfig.Add("enablePasswordRetrieval", "false"); objConfig.Add("enablePasswordReset", "true"); objConfig.Add("requiresQuestionAndAnswer", "true"); objConfig.Add("applicationName", "MyApp"); objConfig.Add("requiresUniqueEmail", "true"); objConfig.Add("maxInvalidPasswordAttempts", "5"); objConfig.Add("passwordAttemptWindow", "10"); objConfig.Add("commandTimeout", "30"); objConfig.Add("passwordFormat", "Hashed"); objConfig.Add("name", "AspNetSqlMembershipProvider"); objConfig.Add("minRequiredPasswordLength", "8"); objConfig.Add("minRequiredNonalphanumericCharacters", "2"); objConfig.Add("passwordStrengthRegularExpression", "(?=^.{8,25}$)(?=.*\d)(?=.*[az])(?=.*[AZ])(?=.*[!@#$%^&*()_+}{\":;'?/>.<,])(?!.*\s).*$")); SqlMembershipProvider objSqlMembershipProvider = new SqlMembershipProvider(); objSqlMembershipProvider.Initialize(objConfig["name"], objConfig); MembershipProviderCollection colMembershipProviders = new MembershipProviderCollection(); colMembershipProviders.Add(objSqlMembershipProvider); colMembershipProviders.SetReadOnly(); BindingFlags enuBindingFlags = BindingFlags.NonPublic | BindingFlags.Static; Type objMembershipType = typeof(Membership); objMembershipType.GetField("s_Initialized", enuBindingFlags).SetValue(null, true); objMembershipType.GetField("s_InitializeException", enuBindingFlags).SetValue(null, null); objMembershipType.GetField("s_HashAlgorithmType", enuBindingFlags).SetValue(null, "SHA1"); objMembershipType.GetField("s_HashAlgorithmFromConfig", enuBindingFlags).SetValue(null, false); objMembershipType.GetField("s_UserIsOnlineTimeWindow", enuBindingFlags).SetValue(null, 15); objMembershipType.GetField("s_Provider", enuBindingFlags).SetValue(null, objSqlMembershipProvider); objMembershipType.GetField("s_Providers", enuBindingFlags).SetValue(null, colMembershipProviders); 

假设您有以下库引用：

 using System.Web.Security; using System.Collections.Specialized; using System.Reflection; 

编辑：

此方法在请求的生命周期中尽早设置成员资格提供程序中的连接字符串

 private void SetMembershipProviderConnectionString(string connectionString) { // Set private property of Membership. Untested code!! var connectionStringField = Membership.Provider.GetType().GetField("_sqlConnectionString", BindingFlags.Instance | BindingFlags.NonPublic); if (connectionStringField != null) connectionStringField.SetValue(Membership.Provider, connectionString); } 

未经测试但从Application_PreRequestHandlerExecute中的Global.asax.cs调用此方法可以完成这项工作。

有一个更简单的解决方案。

1. 创建一个扩展SqlMembershipProvider类的子类。
2. 覆盖Initialize方法
3. 设置connectionString属性config [“connectionString”]
4. 让base.Initialize逻辑继续
5. 在web.config文件中，使用您的自定义类而不是SqlMembershipProvider。 （如果你给它一个不同的免费精选名字大全，请确保设置defaultProvider属性以匹配它）
