wcf - WCF - 将大数据集返回给客户端

问题描述

目标是将表的内容作为数据集发送给客户端。我从客户端应用程序收到错误：

“已超出传入邮件 (65536) 的最大邮件大小配额。”

尽管在从客户端检索大量数据的同一个 WCF 应用程序中没有错误。请查看配置文件。

我已经搜索了一个解决方案，但只是回到了配置文件的调整。WCF 应用程序未报告任何错误，并且客户端正在报告错误。

我试过使用 wsHttpBinding 和 basicHttpBinding 没有成功。我已经尝试过 MTOM 和短信编码。

客户端的应用程序配置文件

这是客户端的 App.Config 文件。

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <system.serviceModel>
        <bindings>
            <wsHttpBinding>
                <binding name="WSHttpBinding_IRestore" messageEncoding="Mtom">
                    <security mode="Transport">
                        <transport clientCredentialType="None" />
                    </security>
                </binding>
                <binding name="WSHttpBinding_IProjectProvider">
                    <security mode="Transport">
                        <transport clientCredentialType="None" />
                    </security>
                </binding>
            </wsHttpBinding>
        </bindings>
        <client>
            <endpoint address="https://myServer.com/Restore.svc"
                binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_IRestore"
                contract="RestoreProvider.IRestore" name="WSHttpBinding_IRestore" />
            <endpoint address="https://myServer.com/ProjectProvider.svc"
                binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_IProjectProvider"
                contract="ProjectProvider.IProjectProvider" name="WSHttpBinding_IProjectProvider" />
        </client>
    </system.serviceModel>
</configuration>

至于 ProjectProvider 服务的绑定信息，唯一的区别是“maxBufferSize”，它在插入时会产生错误。

客户端中的使用代码

Public sub GetZips()
    'Get the information from Ops
    Using oProjectProvider As New ProjectProvider.ProjectProviderClient
        MyDataSet = oProjectProvider.GetZipCodeData
        oProjectProvider.Close()
    End Using
    Application.DoEvents()
End sub

解决方案

我想知道客户端配置。你如何创建对服务的调用？我们最好在客户端和服务器端都应用配置。此外，我怀疑客户端服务端点地址有问题。请发布完整的客户端配置。
另外，请参考下面的配置。 

<binding maxBufferPoolSize="2147483647" 
         maxReceivedMessageSize="2147483647">
    <readerQuotas maxDepth="2147483647" 
                  maxStringContentLength="2147483647" 
                  maxArrayLength="2147483647" 
                  maxBytesPerRead="2147483647"
                  maxNameTableCharCount="2147483647" />
</binding>

如果问题仍然存在，请随时告诉我。
