How to set parameters for stored proc in nlog

[Mike Rutledge]

I'm totally new to this and probably doing it incorrectly. Can someone explain how, in my c# code, do I set the values for the parameters to send to the stored proc?

Below is what my nLog.config file looks like.  I'm assuming somewhere in code I can set these parameter values but I don't see how.

<target xsi:type="Database"

          dbProvider="System.Data.SqlClient"

          connectionStringName="nLogConnectionString"

          keepConnection="false"

          dbDatabase="interface"

          commandType="StoredProcedure"

          commandText=" exec usp_LogParserMessage @Message,@Parser,@Org,@LabOrg,@ChartNum,@AccessionId,@Status,@TransId">

        <parameter name="@Message" layout="${message}"/>

        <parameter name="@Parser" layout="${Parser}"/>

        <parameter name="@Org" layout="${Org}"/>

        <parameter name="@LabOrg" layout="${LabOrg}"/>

        <parameter name="@ChartNum" layout="${ChartNum}"/>

        <parameter name="@AccessionId" layout="${AccessionId}"/>

        <parameter name="@Status" layout="${Status}"/>

        <parameter name="@TransId" layout="${TransId}" />

      </target>

I would appreciate any help. 

Thanks,

Rut
