我正在使用以下链接中的步骤来创建自定义 Create_User_Wizard，但我遇到了一些 METADATA 错误。有人可以帮帮我吗？

http://weblogs.asp.net/gurusakar/archive/2009/01/27/storing-user-profile-into-a-custom-table-using-createuser-wizard-control.aspx

以下是我在 WEB.CONFIG 文件中使用的连接：

<add name="ASPNETDBEntities" connectionString="metadata=res://*/App_Code.ASPNETDB.csdl|res://*/App_Code.ASPNETDB.ssdl|res://*/App_Code.ASPNETDB.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=.\SQLEXPRESS;attachdbfilename=|DataDirectory|\ASPNETDB.MDF;integrated security=True;user instance=True;multipleactiveresultsets=False;App=EntityFramework&quot;" providerName="System.Data.EntityClient" /></connectionStrings>

我在后面的代码中使用以下代码enter code here

         //protected void CreateUserWizard2_CreatedUser(object sender, EventArgs e)
        {

// get the user id of the just created user before the final profile is created

            MembershipUser newUser = Membership.GetUser(CreateUserWizard2.UserName);

            Guid newUserId = (Guid)newUser.ProviderUserKey;

            //Get Profile Data Entered by user in CUW control

            String Country =
            ((TextBox)CreateUserWizard2.CreateUserStep.ContentTemplateContainer.FindControl("Country")).Text;

        // Insert a new record into User_Profile

        // Get your Connection String from the web.config. MembershipConnectionString is the name I have in my web.config


        string connectiontest = ConfigurationManager.ConnectionStrings["ASPNETDBEntities"].C

    onnectionString;

            string insertSql = "INSERT INTO User_Profile(UserId,Country) VALUES(@UserId, @Country)";


            using (SqlConnection myConnection = new SqlConnection(connectiontest))

            {
                myConnection.Open();

                SqlCommand myCommand = new SqlCommand(insertSql, myConnection);

                myCommand.Parameters.AddWithValue("@UserID", newUserId);
                myCommand.Parameters.AddWithValue("@Country", Country);
                myCommand.ExecuteNonQuery();
                myConnection.Close();
            }
        }

一切正常，但是当我单击“创建用户”按钮时，所有数据都从现有字段中插入，但我创建的新字段中的数据没有插入到数据库中，并且它抛出与以下相关的错误一些元数据不支持：

单击“创建用户”按钮后，我收到以下错误

“/”应用程序中的服务器错误。

不支持关键字：“元数据”。

看到您的错误行号：45，您的实体框架和 Ado.net 连接似乎都使用相同的连接字符串：SqlConnection。

您上面显示的 ConnectionString 是您的实体框架。不要将它用于您的 ADO.NET 连接。

ADO.NET 连接字符串示例如下：

"data source=FLOP-PC\Practice;initial catalog=Northwind;integrated security=True"

简而言之，您需要两个连接字符串，一个用于您的实体框架（已经存在）和一个用于您的 ADO.Net 部分的新字符串。
