无法使用服务引用调用 WCF 服务操作答案

【问题标题】：Unable to call WCF service Operation using service reference无法使用服务引用调用 WCF 服务操作

【问题描述】：

我已将 WCF 服务引用添加到控制台应用程序并尝试调用服务操作，但出现 QuotaExceededException。我已经为此寻找解决方案，但我发现我需要更改绑定 maxlength。但这对我来说是不可能的。我不应该更改服务配置。

异常信息：

传入邮件的最大邮件大小配额 (65536) 已达到超过。要增加配额，请使用 MaxReceivedMessageSize 相应绑定元素上的属性。

下面是堆栈跟踪：

   at ConsoleApp2.Program.Main(String[] args) in D:\Work\tempABC\local\ConsoleApp2\ConsoleApp2\Program.cs:line 13

这是我的配置文件内容：

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <system.serviceModel>
        <bindings>
            <wsHttpBinding>
                <binding name="ABC.EUV.Component.Service.Contract.IComponentService">
                    <security mode="None" />
                </binding>
            </wsHttpBinding>
        </bindings>
        <client>
            <endpoint address="http://hyddmosrvi01.vertafore.com/XYZ/WebServices/ComponentService/ComponentService.svc"
                binding="wsHttpBinding" bindingConfiguration="ABC.EUV.Component.Service.Contract.IComponentService"
                contract="ComponentService.IComponentService" name="ABC.EUV.Component.Service.Contract.IComponentService" />
        </client>
    </system.serviceModel>
</configuration>

【问题讨论】：

添加绑定<binding name="binding name.." maxBufferSize="2147483647" maxBufferPoolSize="524288" maxReceivedMessageSize="2147483647"/>到你的app.config
我没有服务。它托管在不同的位置。所以我无法更改配置。
当您将服务引用添加到您的项目时，服务客户端配置会自动包含在您的配置中。所以请分享你的 web.config。看看stackoverflow.com/questions/884235/…
我已经发布了我的配置文件。谢谢

【解决方案1】：

您需要增加消息大小配额，在配置中如下：

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <system.serviceModel>
        <bindings>
            <wsHttpBinding>
                <binding name="ABC.EUV.Component.Service.Contract.IComponentService" maxReceivedMessageSize="200000000" maxBufferSize="200000000" maxBufferPoolSize="200000000">
                    <readerQuotas maxDepth="32" maxArrayLength="200000000" maxStringContentLength="200000000"/>
                    <security mode="None" />
                </binding>
            </wsHttpBinding>
        </bindings>
        <client>
            <endpoint address="http://hyddmosrvi01.vertafore.com/XYZ/WebServices/ComponentService/ComponentService.svc"
                binding="wsHttpBinding" bindingConfiguration="ABC.EUV.Component.Service.Contract.IComponentService"
                contract="ComponentService.IComponentService" name="ABC.EUV.Component.Service.Contract.IComponentService" />
        </client>
    </system.serviceModel>
</configuration>
