我建了个web service,但是当我点生成网站时，出错信息提示说：could not create type 'service',在网上用百度，谷歌查了很久还是没找到解决办法，请大家帮我看看问题到底出在哪里，代码如下：

using System.Web.Services.Protocols;
using System.Configuration;
using System.Data.SqlClient;
using System.Diagnostics;

[WebService(Namespace = "http://www.contentmaster.com/NorthwindServices")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
public class Service : System.Web.Services.WebService
{
public Service () {

//如果使用设计的组件，请取消注释以下行
//InitializeComponent();
}

/*
[WebMethod]
public string HelloWorld() {
return "Hello World";
}
*/

EventLog log = new EventLog("Application");
log.Source = "NorthwindServices";
log.WriteEntry(e.Message, EventLogEntryType.Error);
}

[WebMethod]
public decimal HowMuchWillItCost(string productName, int howMany)
{
SqlConnection sqlConn = null;

try
{
ConnectionStringSettings cs =
ConfigurationManager.ConnectionStrings["NorthwindConnectionString"];
string connString = cs.ConnectionString;
sqlConn = new SqlConnection(connString);
SqlCommand sqlCmd = new SqlCommand();
sqlCmd.CommandText = "SELECT UnitPrice FROM Products " +
"WHERE ProductName = '" + productName + "'";
sqlCmd.Connection = sqlConn;
sqlConn.Open();
decimal price = (decimal)sqlCmd.ExecuteScalar();
return price * howMany;
}
catch (Exception e)
{
// Handle the exception
handleWebException(e);
throw new Exception();

}
finally
{
if (sqlConn != null)
sqlConn.Close();
}

}

}
