WCF分布式开发常见错误（14）:无效的操作异常,At least one operation on the .2011-03-31 博客园 Frank Xu LeiWCF事务编程过程中，会出现这个操作无效异常。信息如下：

At least one operation on the "WCFServiceTransaction1" contract is configured with the TransactionFlowAttribute attribute set to Mandatory but the channel"s binding "NetTcpBinding" is not configured with a TransactionFlowBindingElement. The TransactionFlowAttribute attribute set to Mandatory cannot be used without a TransactionFlowBindingElement.

异常界面如图：

我是在调试客户端事务模式的时候出现的错误，服务契约和服务类的代码如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ServiceModel;
using System.Runtime.Serialization;
using System.Transactions;
using System.Diagnostics;
//ServiceContract 属性以及 Indigo 使用的所有其他属性均在 System.ServiceModel 命名空间中定义，
//因此本例开头使用 using 语句来引用该命名空间。

namespace WCFService
{
     //1.服务契约
     [ServiceContract（Namespace = "http://www.cnblogs.com/frank_xl/"）]
     public interface IWCFServiceTransaction1
     {
         //操作契约
         [OperationContract]
         //强制事务流，使用客户端事务
         //[TransactionFlow（TransactionFlowAttribute
         [TransactionFlow（TransactionFlowOption.Mandatory）]
         bool AddNewData（string name）;

     }
     //2.服务类，实现契约
     //事务有10分钟的超时限制
     //[ServiceBehavior（IncludeExceptionDetailInFaults = true）]
     [ServiceBehavior（IncludeExceptionDetailInFaults = true, TransactionTimeout = "00:30:00"）]
     public class WCFServiceTransaction1 : IWCFServiceTransaction1
     {
         //实现接口定义的方法
         //需要事务环境，启动事务
         [OperationBehavior（TransactionScopeRequired = true, TransactionAutoComplete = true）]
         public bool AddNewData（string name）
         {
             Transaction transaction = Transaction.Current;
             Debug.Assert（System.Transactions.Transaction.Current.TransactionInformation.DistributedIdentifier！=Guid.Empty）;
             Console.WriteLine（"Create a new Transaction at {0}", System.Transactions.Transaction.Current.TransactionInformation.CreationTime）;
             Console.WriteLine（"WCFService 1 Transaction Status is {0}", System.Transactions.Transaction.Current.TransactionInformation.Status）;
             Console.WriteLine（"WCFService 1 Transaction LocalIdentifier is {0}", System.Transactions.Transaction.Current.TransactionInformation.LocalIdentifier）;
             Console.WriteLine（"WCFService 1 Transaction DistributedIdentifier is {0}", System.Transactions.Transaction.Current.TransactionInformation.DistributedIdentifier）;

             //using （System.Transactions.TransactionScope ts = new System.Transactions.TransactionScope（））
             //{
             try
             {
                 using （userTableAdapter adapter = new userTableAdapter（））
                 {
                     if （1 == adapter.CreateUser（name））
                     {
                         Console.WriteLine（"Calling WCF Transaction sucessfullyname length is:{0}", name.Length）;
                     }
                     else
                     {
                         Console.WriteLine（"Calling WCF Transaction unsucessfullyname length is:{0}", name.Length）;
                         //return false;
                     }
                 }
             }
             catch （Exception e）
             {
                 Console.WriteLine（"Calling WCF Transaction error:{0}", e.Message）;
                 throw e;
                 //return false;
             }

             //ts.Complete（）;
             return true;

         }
     }
