我有一个创建用户向导控件，并为其添加了更多字段，并希望将该额外信息存储到同一个数据库中的另一个表中。我已经尝试了几个教程，但似乎都没有。下面的一个，我得到错误，“对象引用未设置为对象的实例”
我做错了什么。也许我需要为我设置的桌子做些额外的事情？链接等会有所帮助。感谢
表名是ExtraUserInfo。其他表是成员资格服务的默认设置.... aspnet_reqsql.exe
这是来源
<asp:SqlDataSource ID="ExtraUserInfo" runat="server" ConnectionString="LoginSQL"
InsertCommand="INSERT INTO [ExtraUserInfo] ([CompanyName]) VALUES (@CompanyName)"
ProviderName="MySqlLoginProvider">

protected void CreateUserWizard1_CreatedUser(object sender, EventArgs e)
{
Guid userFKey;
MembershipUser mu = Membership.GetUser(CreateUserWizard1.UserName);
userFKey = (Guid)mu.ProviderUserKey;
TextBox UserNameTextBox = (TextBox)CreateUserWizardStep1.ContentTemplateContainer.FindControl("CompanyName");
SqlDataSource DataSource = (SqlDataSource)CreateUserWizardStep1.ContentTemplateContainer.FindControl("ExtraUserInfo");
object UserGUID = mu.ProviderUserKey;
DataSource.InsertParameters.Add("UserId", UserGUID.ToString());
DataSource.Insert();
}
完整错误
Line 48: object UserGUID = mu.ProviderUserKey;
Line 49:
Line 50: DataSource.InsertParameters.Add("UserId", UserGUID.ToString());
Line 51: DataSource.Insert();

在代码中，请遵循以下内容：我从这里获得{http://www.4guysfromrolla.com/articles/070506-1.aspx}
protected void CreateUserWizard1_CreatedUser(object sender, EventArgs e)
{
TextBox UserNameTextBox = (TextBox)CreateUserWizardStep2.ContentTemplateContainer.FindControl("UserName");
SqlDataSource DataSource = (SqlDataSource)CreateUserWizardStep2.ContentTemplateContainer.FindControl("InsertExtraInfo");
MembershipUser User = Membership.GetUser(UserNameTextBox.Text);
object UserGUID = User.ProviderUserKey;
DataSource.InsertParameters.Add("UserId", UserGUID.ToString());
DataSource.Insert();
}
