ASP.NET Web服务无法与IIS7中的数据库连接

Question

When I try to publish my asp.net web service application on IIS7, my application works perfect when debugging with Visual Studio. But, when I try to access my webservice from IIS by typing on browser: http://localhost:port/Service1.asmx and click on the method and then click "Invoke" it gives me this error:

System.Data.SqlClient.SqlException: The SELECT permission was denied on the object 'Marimi', database 'eMagazin', schema 'dbo'.
   at System.Data.SqlClient.SqlConnection.OnError(SqlException exception, Boolean breakConnection, Action`1 wrapCloseInAction)
   at System.Data.SqlClient.SqlInternalConnection.OnError(SqlException exception, Boolean breakConnection, Action`1 wrapCloseInAction)

   at WebService.Service1.GetMarime() in C:\Users\Eduard\Desktop\MaG_beta01\MaG\WebService\Service1.asmx.cs:line 741

My Connection to database in web.Config is :

<connectionStrings>
    <add name="connection" connectionString="Data Source=EDUARD-PC\EDD;Initial Catalog=eMag; Integrated Security=True;" providerName="System.Data.SqlClient"/>
  </connectionStrings>

and I use as Application Pool the ASP.NET v4.0 Classic

I've searched for the solutions on google but I haven't found anything helpful.... Thank you all in advance...

“应用程序池标识”对您的数据库没有权限：要么不使用集成安全性，要么为拥有数据库权限的appool创建专用用户。
