来个高手解决下啊......

我的WCF服务是用 WEB --> WCF应用程序建的 (WCF服务和数据库在一台 服务器)

在本地调试没问题(放在IIS7下也没问题)

应用程序部署到客户端就报错
exp = {"通信对象 System.ServiceModel.Channels.ServiceChannel 无法用于通信，因为其处于“出错”状态。"}

我也遇到这个问题了，不过我的发现是，数据量过大的话就出现这个问题，如果小一些就不会

拿我的项目说，商品信息3000多条时传输就会报错，如果在100条左右就不会。

期待解决方法，同谢了。

客户端代理建立以后，长时间不使用，就会出现出错状态，进而无法使用。
如果通道出错，进行重新连接即可，。或者重新实例化一个客户端代理。以前的销毁掉
（可以通过代理的State 是否为Faulted）

修改为
<identity>
                    <servicePrincipalName value="host/GavinLuo-PC" />
</identity>
msdn上说，servicePrincipalName  (WCF) 客户端通过此标识连接到终结点，则它在使用此终结点进行 SSPI 身份验证时将使用 SPN。
userPrincipalName    (WCF) 客户端在使用终结点进行 SSPI 身份验证时将使用 UPN。

试试~

谢谢,但是试了不行

修改 Web.config 
 <system.serviceModel>

        <bindings>

            <wsHttpBinding>

                <binding name="httpconf">

                    <security mode="None">

                        <transport clientCredentialType="Windows"/>

                        <message clientCredentialType="Windows"/>

                    </security>

                </binding>
