profile的4个关键应用(学习笔记)

1为匿名用户进行个性化设置

web.config配置

    

<anonymousIdentification enabled="true"/>

    <profile>

      <properties>

        <add name="Name" allowAnonymous="true" />

        <add name="LastSubmit" type="System.DateTime" allowAnonymous="true"/>

        <group name="Address">

          <add name="City"  allowAnonymous="true"/>

          <add name="PostalCode"  allowAnonymous="true"/>

        </group>

      </properties>

</profile>

代码：

    

protected void Page_Load(object sender, EventArgs e)

    {

        if (!Page.IsPostBack)

        {

            //显示用户配置信息

            DisplayProfileInfo();

        }

    }

    protected void btnSubmit_Click(object sender, EventArgs e)

    {

        //保存用户配置信息到Profile属性中

        Profile.Name = txtName.Text;

        Profile.Address.City = txtCity.Text;

        Profile.Address.PostalCode = txtPostalCode.Text;

        Profile.LastSubmit = DateTime.Now;

        //显示用户配置信息

        DisplayProfileInfo();

    }

    private void DisplayProfileInfo()

    {

        //从Profile属性中获取数据并赋值给服务器控件           

        txtName.Text = Profile.Name;

        txtCity.Text = Profile.Address.City;

        txtPostalCode.Text = Profile.Address.PostalCode;

        DateTime time = Profile.LastSubmit;

        //如果未获取值则显示空，否则显示获取的值

        if (time.Year == 1)

        {

            labLastSubmit.Text = "空";

        }

        else

        {

            labLastSubmit.Text = time.ToString();

        }

    }

2、为注册用户实现个性化用户配置

web.config配置

    

<connectionStrings>

        <add name="NorthwindConnectionString" connectionString="Data Source=localhost;Initial Catalog=Northwind;Integrated Security=True"

            providerName="System.Data.SqlClient" />

    </connectionStrings>

    <system.web>        

          <profile>

              <properties>

                   <add name="ShoppingCart" type="ShoppingCart" serializeAs="Binary"/>

              </properties>           

          </profile>

          <authorization>

              <deny users="?"/>

          </authorization>

          <authentication mode="Forms">

              <forms loginUrl ="Login.aspx"></forms>

          </authentication>

代码示例：code 13-2

3、匿名用户转化为注册用户的处理

Global.asax中的设置

    

void Profile_MigrateAnonymous(Object sender, ProfileMigrateEventArgs pe)

       示例代码：code 13-3

4、删除个性化信息

删除匿名用户的个性化信息

ProfileManager.DeleteProfile(Context.Request.AnonymousID)

删除注册用户的个性化信息

ProfileManager.DeleteProfile(User.Identity.Name)
