    I have solved this issue by using this Code in my Service.config file. 

    <services>
      <service name="Service.IService">
        <clear />
        <endpoint binding="basicHttpBinding" contract="Service.IService" />
      </service>
    </services>
    <bindings>
      <basicHttpBinding>
        <binding maxBufferSize="2147483647" maxReceivedMessageSize="2147483647">
          <readerQuotas maxDepth="32" maxStringContentLength="2147483647"
            maxArrayLength="16348" maxBytesPerRead="4096" maxNameTableCharCount="16384" />
        </binding>
      </basicHttpBinding>
      <webHttpBinding>
        <binding maxBufferSize="2147483647" maxReceivedMessageSize="2147483647" />
      </webHttpBinding>
    </bindings>
