asp.net 2.0 自定义 基于 Table 的 Profile Provide

最近公司里要求统计用户注册的省市什么的乱七八糟的信息,asp.net 2.0自带的那个 ProfileProvider满足不了。从http://www.asp.net/downloads/sandbox/table-profile-provider-samples/下载了他的源码，觉的那个东西太啰嗦了，不过收益非浅。自己在此基础上又做了一些改进。源码如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Web;
using System.Web.Profile;
using System.Configuration;
using System.Collections.Specialized;
using System.Data;
using System.Data.SqlClient;
namespace yxyProviders
{
public class yxyProfileProvider : ProfileProvider
{
string _appName;
string _cnnName;
public override void Initialize(string name, NameValueCollection config)
{
if (config == null)
throw new ArgumentNullException("config");
if (String.IsNullOrEmpty(name))
name = "yxyProfileProvider";
_cnnName = config["connectionStringName"];
if (String.IsNullOrEmpty(_cnnName))
throw new ConfigurationErrorsException("connectionStringName not specified");
string _appName = config["applicationName"];
if (string.IsNullOrEmpty(_appName))
throw new ConfigurationErrorsException("applicationName not specified");
base.Initialize(name, config);
}

public override int DeleteInactiveProfiles(ProfileAuthenticationOption authenticationOption, DateTime userInactiveSinceDate)
{
throw new NotImplementedException();
}

public override int DeleteProfiles(string[] usernames)
{
using (SqlConnection cnn = new SqlConnection(ConfigurationManager.ConnectionStrings[_cnnName].ConnectionString))
using (SqlCommand cmd = cnn.CreateCommand())
{
cnn.Open();
cmd.CommandText = "app_DeleteUserProfile";
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add("@UserName", SqlDbType.NVarChar, 255);
foreach (string s in usernames)
{
cmd.Parameters[0].Value = s;
cmd.ExecuteNonQuery();
}
cnn.Close();
}
return 0;
}

public override int DeleteProfiles(ProfileInfoCollection profiles)
{
return 0；
}

public override ProfileInfoCollection FindInactiveProfilesByUserName(ProfileAuthenticationOption authenticationOption, string usernameToMatch, DateTime userInactiveSinceDate, int pageIndex, int pageSize, out int totalRecords)
{
throw new NotImplementedException();
}

public override ProfileInfoCollection FindProfilesByUserName(ProfileAuthenticationOption authenticationOption, string usernameToMatch, int pageIndex, int pageSize, out int totalRecords)
{
throw new NotImplementedException();
}

public override ProfileInfoCollection GetAllInactiveProfiles(ProfileAuthenticationOption authenticationOption, DateTime userInactiveSinceDate, int pageIndex, int pageSize, out int totalRecords)
{
throw new NotImplementedException();
}

public override ProfileInfoCollection GetAllProfiles(ProfileAuthenticationOption authenticationOption, int pageIndex, int pageSize, out int totalRecords)
{
throw new NotSupportedException();
}

public override int GetNumberOfInactiveProfiles(ProfileAuthenticationOption authenticationOption, DateTime userInactiveSinceDate)
{
throw new NotImplementedException();
}

public override string ApplicationName
{
get
{
return _appName;
}
set
{
_appName = value;
}
}

public override SettingsPropertyValueCollection GetPropertyValues(SettingsContext context, SettingsPropertyCollection collection)
{
SettingsPropertyValueCollection svc = new SettingsPropertyValueCollection();
foreach (SettingsProperty prop in collection)
{
SettingsPropertyValue value = new SettingsPropertyValue(prop);
value.PropertyValue = prop.DefaultValue;
svc.Add(value);
}
if (collection == null || collection.Count < 1 || context == null)
return svc;
string name = (string)context["UserName"];
bool userIsAuthenticated = (bool)context["IsAuthenticated"];

using (SqlConnection cnn = new SqlConnection(ConfigurationManager.ConnectionStrings[_cnnName].ConnectionString))
using (SqlCommand cmd = cnn.CreateCommand())
{
cnn.Open();
cmd.CommandText = "app_GetUserProfile";
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add("@UserName", SqlDbType.NVarChar, 255);
cmd.Parameters[0].Value = name;
using (SqlDataReader dr = cmd.ExecuteReader())
{
if (dr.Read())
{
foreach (SettingsProperty prop in collection)
{
string persistenceData = prop.Attributes["CustomProviderData"] as string;
string[] chunk = persistenceData.Split(new char[] { ';' });
svc[prop.Name].PropertyValue = dr[chunk[3]];
}
}
}
cnn.Close();
}
return svc;
}

public override void SetPropertyValues(SettingsContext context, SettingsPropertyValueCollection collection)
{
string objValue = (string)context["UserName"];
bool userIsAuthenticated = (bool)context["IsAuthenticated"];

using (SqlConnection cnn = new SqlConnection(ConfigurationManager.ConnectionStrings[_cnnName].ConnectionString))
using (SqlCommand cmd = cnn.CreateCommand())
{
cnn.Open();
cmd.CommandText = "app_SaveUserProfile";
cmd.CommandType = CommandType.StoredProcedure;
foreach (SettingsPropertyValue pi in collection)
{
string cpdata = pi.Property.Attributes["CustomProviderData"] as string;
string[] args = cpdata.Split(new char[] { ';' });
SqlDbType dbtype = (SqlDbType)Enum.Parse(typeof(SqlDbType), args[1], true);
int size = int.Parse(args[2]);
SqlParameter pa = new SqlParameter(args[0], dbtype, size);
pa.Value = pi.PropertyValue;
cmd.Parameters.Add(pa);
}
cmd.ExecuteNonQuery();
cnn.Close();
}

}
}
}

-------------------------web.config人配置如下：
<connectionStrings>
<add name="wwwUserConn" connectionString="Data Source=dhz-pc/db2005;Initial Catalog=wwwUser;Integrated Security=True" providerName="System.Data.SqlClient"/>
</connectionStrings>

<profile enabled="true" defaultProvider="yxyTableProfile">
<providers>
<clear/>
<add name="yxyTableProfile" type="yxyProviders.yxyProfileProvider,yxyProviders" connectionStringName="wwwUserConn" applicationName="wwwUserConn"
/>
</providers>
<properties>
<add name="UserName" customProviderData="@UserName;nvarchar;255;UserName" type="string" defaultValue=""/>
<add name="Age" customProviderData="@Age;nvarchar;255;Age" type="int" defaultValue="0"/>
<add name="Province" customProviderData="@Province;nvarchar;255;Province" type="string" defaultValue=""/>
</properties>
</profile>
----------------------------------------用法----------------
MembershipUser mu = Membership.GetUser();
if (mu != null)
{
ProfileCommon pfc = Profile.GetProfile(mu.UserName);
pfc.Age =30;
pfc.UserName = mu.UserName;
pfc.Province = "HuBei";
pfc.Save();
}
----------------------------------补充；
这个实现其实是不完整的。

像 匿名用户是就有问题。不过，在解决的时候，处理匿名时我将他的用户名设为 一个临时的GUID并存到 客户机的COOKIE中。DB那里有个JOB调度，每天晚上自动删除那些超过一定时间的用户PROFILE数据。

--------------------SqlScript

create table app_UserProfile(
UserName nvarchar(255),
Age int ,
Province nvarchar(255)
)
go
create proc app_GetUserProfile
@UserName nvarchar(255)
as
begin
Select UserName,Age,Province from app_UserProfile where UserName=@UserName
end
go
create proc app_SaveUserProfile
@UserName nvarchar(255),
@Age int ,
@Province nvarchar(255)
as
begin
if exists(select * from app_UserProfile where UserName=@UserName)
begin
update app_UserProfile
set Age=@Age,Province=@Province
where UserName=@UserName
end
else
begin
insert into app_UserProfile(UserName,Age,Province)
values(@UserName,@Age,@Province)
end
end
go
create proc app_DeleteUserProfile
@UserName nvarchar(255)
as
begin
delete app_UserProfile where UserName=@UserName
end
