我是 .net 和 WCF 的新手。我正在尝试构建一个 WCF 服务原型，该原型将从数据库表中获取数据，并根据数据使用 SMTP 交换发送电子邮件。
对于原型，我创建了一个接口和服务，并在 IIS 5.1 中托管了 WCF 服务。对于我的测试控制台，我已经引用了这个服务。现在，当我运行我的应用程序时，我从控制台收到错误消息。
这是代码的样子：
namespace MyWcfConsoleApp
{
class Program
{
static void Main(string[] args)
{
// Create a proxy object and connect to the service
EmailServiceClient proxy = new EmailServiceClient();
// Test the operations in the service
Console.WriteLine("Test1");
//BulkEmailDTOList EmailInfo = proxy.GetBulkEmailInfo(1);
EmailService.IEmailService EmailInfo = ServiceLocator.Resolve<IEmailService>();
BulkEmailDTOList result = new BulkEmailDTOList();
result = EmailInfo.GetBulkEmailInfo(1);
这就是我在控制台应用程序中的 App.Config 中的内容：

请让我知道我做错了什么。有什么简单的方法可以调用 DTO 来检索我的数据吗？正如我所说，我对此很陌生，所以度过了艰难的时光..
这是我的实现：
using BulkEmailDac = WW.Common.DataAccess.Impl.BulkEmailDac;
namespace WW.Common.Service.Impl
{
public class EmailService : IEmailService
{
private BulkEmailDac emailDac;
ErrorMsg err_msg = new ErrorMsg();
public EmailService()
{
emailDac = new BulkEmailDac();
}
public BulkEmailDTOList GetBulkEmailInfo(int recordLimit)
{
try
{
return emailDac.GetBulkEmailInfo(recordLimit);
}
catch (Exception ex)
{
if (ex is FaultException<OperationFault>)
{
throw;
}
else
{
//LOG AND THROW AN UNKNOWN EXCEPTION
ApplicationLog.WriteError(DateTime.Now.ToString() + "|"
+ "GetBulkEmailInfo" + "|"
+ ex.Message + "|"
+ ex.StackTrace);
throw new FaultException<OperationFault>(new OperationFault(ex.Message, ErrorMessages.Unknown_Error_Code));
}
}
这是合同：
namespace WW.Common.Service.Contract
{
[ServiceContract]
public interface IEmailService
{
[OperationContract]
double Add(double n1, double n2);
[OperationContract]
double Subtract(double n1, double n2);
[OperationContract]
double Multiply(double n1, double n2);
[OperationContract]
double Divide(double n1, double n2);
[OperationContract]
[FaultContractAttribute(typeof(OperationFault))]
BulkEmailDTOList GetBulkEmailInfo(int recordLimit);
[OperationContract]
string Abc(string s1);
}
这是我的服务中的 Web.Config 文件：
