Web应用程序项目 - 如何使用ProfileCommon

Question

I am porting a site I had developed on an old box across to a new dev env. I have not just copied all the files as I didn't have a great file structure and some parts of the code needed to be removed as I went along.

Originally I had created a website (File -> New -> Web Site). I wanted a file structure something like:

Popular folder structure for build

So I created a new blank solution so the sln file was on its own, then added projects (various DLL projects) and am ASP.NET Web Application.

This last part seems to have caused me a few issues, I am now getting the following error:

"The type or namespace name ' ProfileCommon' could not be found".

I found the following page:

http://weblogs.asp.net/joewrobel/archive/2008/02/03/web-profile-builder-for-web-application-projects.aspx

It seems a bit long winded and I was hoping someone might know of a better solution.

I am trying to use the ProfileCommon with the CreateUser Wizard as I add a little extra information into it.

protected void CreateUserWizard1_CreatedUser(object sender, EventArgs e)
{
    // Create an empty Profile for the newly created user
    ProfileCommon p = (ProfileCommon)ProfileCommon.Create(CreateUserWizard1.UserName, true);

    // Populate some Profile properties off of the create user wizard
    p.CurrentLevel = Int32.Parse(((DropDownList)CreateUserWizard1.CreateUserStep.ContentTemplateContainer.FindControl("clevel")).SelectedValue);

    // Save profile - must be done since we explicitly created it
    p.Save();
}

Web.config:

<profile enabled="true">
<properties>
    <add name="CurrentLevel" type="Int32"/>
</properties>
</profile>

If there is another way to add this extra information into the creation wizard, or just a better way of setting extra info to a new user then I am all ears and would be very grateful.

Thanks for the help and advice.

Answer 1

This is a very late post, but I just ran into this same problem when porting a VB.NET Visual Studio 2008 (.NET 3.5) website over to C# Visual Studio 2010 (.NET 4.0) website.

I found references to ProfileCommon in MSDN's ProfileBase documentation, but nothing on how to get that object.

From your helpful MSDN link, I noticed that ProfileCommon would only ever be just a wrapper for the HttpContext .

In short, I used the var keyword to extract the ProfileCommon information from the HttpContext , as in:

var profile = HttpContext.Current.Profile;

Using this one bit of information, I was able to create the entire class for reading and writing the information for my website visitors.

Like you, I hope this code might help someone else:

using System.Web;
using System.Web.Security;

namespace WebApplication17 {

  public partial class ManageProfile : System.Web.UI.Page {

    protected void Page_Load(object sender, EventArgs e) {
      if (!IsPostBack) {
        if (User.Identity.IsAuthenticated) {
          loadProfile();
        } else {
          goHome();
        }
      }
    }

    private void changePassword(string pwdOld, string pwdNew) {
      MembershipUser user = Membership.GetUser(User.Identity.Name);
      user.ChangePassword(pwdOld, pwdNew);
      Membership.UpdateUser(user);
    }

    private void goHome() {
      Server.Transfer("Default.aspx");
    }

    private void loadProfile() {
      MembershipUser user = Membership.GetUser(User.Identity.Name);
      txtEmail.Text = user.Email;
      TextBox3.Text = user.GetPassword();
      var profile = HttpContext.Current.Profile;
      txtTitle.Text = profile.GetPropertyValue("Title").ToString();
      txtName.Text = profile.GetPropertyValue("Name").ToString();
      txtAddress.Text = profile.GetPropertyValue("Address").ToString();
      txtCity.Text = profile.GetPropertyValue("City").ToString();
      txtSt.Text = profile.GetPropertyValue("St").ToString();
      txtZip.Text = profile.GetPropertyValue("Zip").ToString();
      txtPhone.Text = profile.GetPropertyValue("Phone").ToString();
      txtFax.Text = profile.GetPropertyValue("Fax").ToString();
      txtCompany.Text = profile.GetPropertyValue("Company").ToString();
    }

    private void setProfile() {
      MembershipUser user = Membership.GetUser(User.Identity.Name);
      user.Email = txtEmail.Text;
      Membership.UpdateUser(user);
      var profile = HttpContext.Current.Profile;
      profile.SetPropertyValue("Title", txtTitle.Text);
      profile.SetPropertyValue("Name", txtName.Text);
      profile.SetPropertyValue("Address", txtAddress.Text);
      profile.SetPropertyValue("City", txtCity.Text);
      profile.SetPropertyValue("St", txtSt.Text);
      profile.SetPropertyValue("Zip", txtZip.Text);
      profile.SetPropertyValue("Phone", txtPhone.Text);
      profile.SetPropertyValue("Fax", txtFax.Text);
      profile.SetPropertyValue("Company", txtCompany.Text);
      profile.Save();
    }

    protected void Button6_Click(object sender, EventArgs e) {
      changePassword(TextBox3.Text, TextBox4.Text);
      goHome();
    }

    protected void Button11_Click(object sender, EventArgs e) {
      setProfile();
      goHome();
    }

  }

}

I found "a" solution to this one. Not sure if it is the best one or not but it worked for my situation. Minimal code changes required.

Hope it might help someone else, (or me when I forget it again).
