c# - Declaring 2 similar anonymous objects -

below declaration of 2 anonymous objects. second 1 exact same copy of first 1 except there no lastrefresh element inside it.

is there way declare these 2 objects without duplicating exact same portion?

var routevaluesforautorefresh = new {     page = @viewbag.nextpage,     lastrefresh = @viewbag.lastrefresh,     searchterm = request["searchterm"],     searchcolumn = request["searchcolumn"],     searchorder = request["searchorder"],     searchdescending = (request["searchdescending"] ?? "true").tolower().indexof("true") > -1,     requeststatus0 = (request["requeststatus0"] ?? "false").tolower().indexof("true") > -1,     requeststatus1 = (request["requeststatus1"] ?? "true").tolower().indexof("true") > -1,     requeststatus3 = (request["requeststatus3"] ?? "true").tolower().indexof("true") > -1,     requeststatus5 = (request["requeststatus5"] ?? "true").tolower().indexof("true") > -1,     requeststatus7 = (request["requeststatus7"] ?? "true").tolower().indexof("true") > -1,     requeststatus9 = (request["requeststatus9"] ?? "true").tolower().indexof("true") > -1 }; var routevaluesfornextpage = new {     page = @viewbag.nextpage,     searchterm = request["searchterm"],     searchcolumn = request["searchcolumn"],     searchorder = request["searchorder"],     searchdescending = (request["searchdescending"] ?? "true").tolower().indexof("true") > -1,     requeststatus0 = (request["requeststatus0"] ?? "false").tolower().indexof("true") > -1,     requeststatus1 = (request["requeststatus1"] ?? "true").tolower().indexof("true") > -1,     requeststatus3 = (request["requeststatus3"] ?? "true").tolower().indexof("true") > -1,     requeststatus5 = (request["requeststatus5"] ?? "true").tolower().indexof("true") > -1,     requeststatus7 = (request["requeststatus7"] ?? "true").tolower().indexof("true") > -1,     requeststatus9 = (request["requeststatus9"] ?? "true").tolower().indexof("true") > -1 }; 

there no syntax it, have couple of decent workarounds:

• make class named, , derive 1 other (or derive both common base)
• make third anonymous object common fields, use in both "real" named objects
• make individual local variables, , use them make fields of both anonymous objects.

i prefer first approach, other 2 approaches improvement.

here example of second approach:

var routevaluesfornextpage = new {     page = @viewbag.nextpage,     searchterm = request["searchterm"],     searchcolumn = request["searchcolumn"],     searchorder = request["searchorder"],     searchdescending = (request["searchdescending"] ?? "true").tolower().indexof("true") > -1,     requeststatus0 = (request["requeststatus0"] ?? "false").tolower().indexof("true") > -1,     requeststatus1 = (request["requeststatus1"] ?? "true").tolower().indexof("true") > -1,     requeststatus3 = (request["requeststatus3"] ?? "true").tolower().indexof("true") > -1,     requeststatus5 = (request["requeststatus5"] ?? "true").tolower().indexof("true") > -1,     requeststatus7 = (request["requeststatus7"] ?? "true").tolower().indexof("true") > -1,     requeststatus9 = (request["requeststatus9"] ?? "true").tolower().indexof("true") > -1 }; var routevaluesforautorefresh = new {     routevaluesfornextpage ,   lastrefresh = @viewbag.lastrefresh }; 

here example of third approach:

var page = @viewbag.nextpage; var searchterm = request["searchterm"]; var searchcolumn = request["searchcolumn"]; var searchorder = request["searchorder"]; var searchdescending = (request["searchdescending"] ?? "true").tolower().indexof("true") > -1; var requeststatus0 = (request["requeststatus0"] ?? "false").tolower().indexof("true") > -1; var requeststatus1 = (request["requeststatus1"] ?? "true").tolower().indexof("true") > -1; var requeststatus3 = (request["requeststatus3"] ?? "true").tolower().indexof("true") > -1; var requeststatus5 = (request["requeststatus5"] ?? "true").tolower().indexof("true") > -1; var requeststatus7 = (request["requeststatus7"] ?? "true").tolower().indexof("true") > -1; var requeststatus9 = (request["requeststatus9"] ?? "true").tolower().indexof("true") > -1;  var routevaluesforautorefresh = new {     page,     lastrefresh = @viewbag.lastrefresh,     searchterm,     searchcolumn,     searchorder,     searchdescending,     requeststatus0,     requeststatus1,     requeststatus3,     requeststatus5,     requeststatus7,     requeststatus9 }; var routevaluesfornextpage = new {     page,     searchterm,     searchcolumn,     searchorder,     searchdescending,     requeststatus0,     requeststatus1,     requeststatus3,     requeststatus5,     requeststatus7,     requeststatus9 };
