命名空间问题（wcf服务中的程序集问题 [英] Namespace Issue (Assembly issue in wcf services

问题描述

请在WCF中查看以下URL expalin self hostin。



WCF自托管示例 [ ^ ]



在这个例子中，我在编写下面的代码时遇到错误



cutomerList.Where（p => p.CustomerID == obj.CustomerID）.Update（p => p.CustomerName = obj.CustomerName）;



错误是



'System.Collections.Generic.IEnumerable< saleclasslibrary.customer>'不包含'Update'并且没有扩展方法'Update'接受类型为'System.Collections.Generic.IEnumerable< saleclasslibrary.customer>'的第一个参数'（您是否缺少using指令或汇编引用？）D：\ DotNet\WCFProject\SaleClassLib rary \SaleService.cs 33 29 SaleClassLibrary



你能告诉我这个的实际解决方案或我想念的是什么？

Please check the below URL which expalin self hostin in WCF.

WCF Self Hosting with Example [^]

In this example I am getting error while writing the below code

cutomerList.Where(p => p.CustomerID == obj.CustomerID).Update(p => p.CustomerName = obj.CustomerName);

The error is

'System.Collections.Generic.IEnumerable<saleclasslibrary.customer>' does not contain a definition for 'Update' and no extension method 'Update' accepting a first argument of type 'System.Collections.Generic.IEnumerable<saleclasslibrary.customer>' could be found (are you missing a using directive or an assembly reference?) D:\DotNet\WCFProject\SaleClassLibrary\SaleService.cs 33 29 SaleClassLibrary

Can you tell me the actual solution for this or what refrence I am missng ?
