pic.ImageURL = virtualFolder + filename + extension;
pic.Date = System.DateTime.Today;
}
解决方案
看起来像您的应用程序运行在SQL Server中不存在的帐户下。因此，您在Entity Framework的连接字符串中指定了登录名和密码，我想您需要从此实体框架连接字符串中删除 Integrated Security = True;
< add name =DatabaseEntities
connectionString =metadata = res：//*/App_Code.Model.csdl | res：/ /*/App_Code.Model.ssdl|res://*/App_Code.Model.msl;provider=System.Data.SqlClient;provider connection string =& quot;数据源= ASPHOST166\SQL2008R2,778;初始目录= Rennoz_DATABASEMDF; User ID = Rennoz_Admin; Password = *****; Integrated Security = True; User Instance = True; MultipleActiveResultSets = True& quot;
providerName =System.Data.EntityClient/>
更新：根据您的错误消息，您的SQL Server版本不支持用户实例登录标志。所以也删除 User Instance = True; 参数。
could anyone help me with this ? Everything works fine in Visual Studio, but does not on a remote server. I have tried to access the page while logged in and logged out, but has got the same error. Error : "System.Data.SqlClient.SqlException: Login failed for user 'ASPHOST166\IWAM_plesk(default)'."

解决方案
Looks like your application runs under account which is not exist in SQL server. Thus you have login and password specified in connection string for Entity Framework, I think you need remove Integrated Security=True; from this Entity Framework connections string:
<add name="DatabaseEntities"
connectionString="metadata=res://*/App_Code.Model.csdl|res://*/App_Code.Model.ssdl|res://*/App_Code.Model.msl;provider=System.Data.SqlClient;provider connection string="Data Source=ASPHOST166\SQL2008R2,778; Initial Catalog=Rennoz_DATABASEMDF; User ID=Rennoz_Admin; Password=*****;Integrated Security=True;User Instance=True;MultipleActiveResultSets=True""
providerName="System.Data.EntityClient" />
UPDATE: According to your error message, user instance login flag is not supported on your version of SQL server. So remove also User Instance=True; parameter.
