    Hi,

    Use the below code to create look up in SharePoint List.
    //Source list to add lookup column
    SPList srcList=Web.lists["My List"];
    //Lookup list
    SPList lookUpList = web.Lists["User Roles"];
    //Creeate Lookup column
    srcList.Fields.AddLookup("Lookup Column", lookUpList .ID, false);
    //Assign reference column from lookup list

    SPFieldLookup lkp = (SPFieldLookup)srcList.Fields["Lookup Column"];
    lkp.LookupField = lookUpList .Fields["Title"].InternalName;
    lkp.Update();

    Thanks and Regards,
