在ide.config里加入以下内容便可

    <system.serviceModel>
        <client>
            <endpoint binding="customBinding" bindingConfiguration="testBinding" contract="IMetadataExchange" name="http"/>
        </client>
        <bindings>
            <customBinding>
                <binding name="testBinding">
                    <textMessageEncoding>
                        <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647"/>
                    </textMessageEncoding>
                    <httpTransport transferMode="Buffered" maxReceivedMessageSize="2147483647" maxBufferSize="2147483647"/>
                </binding>
            </customBinding>
        </bindings>
    </system.serviceModel>
