调用webservice时用代码进行配置

请问各位，我想调用webservice ,但是因为某种原因，我不能使用app.config配置WebService信息,也就是说我要在调用前写代码替换如下配置：<system.serviceModel>
        <bindings>
            <basicHttpBinding>
                <binding name="IUserInfoServiceHttpBinding" closeTimeout="00:01:00"
                    openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"
                    allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
                    maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536"
                    messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered"
                    useDefaultWebProxy="true">
                    <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
                        maxBytesPerRead="4096" maxNameTableCharCount="16384" />
                    <security mode="None">
                        <transport clientCredentialType="None" proxyCredentialType="None"
                            realm="">
                            <extendedProtectionPolicy policyEnforcement="Never" />
                        </transport>
                        <message clientCredentialType="UserName" algorithmSuite="Default" />
                    </security>
                </binding>
            </basicHttpBinding>
        </bindings>
        <client>
            <endpoint address="http://192.168.1.118:7001/arsipWebService/service/IUserInfoService"
                binding="basicHttpBinding" bindingConfiguration="IUserInfoServiceHttpBinding"
                contract="UserInfoService.IUserInfoServicePortType" name="IUserInfoServiceHttpPort" />
        </client>
    </system.serviceModel>
