asp.net mvc - Type of Iqueryable at runtime -

i have method returns iqueryable result, result based on if else condition, if condition satisfies use "assetdetails" class object ,otherwise "userandclientdetails" object. here code:

  private iqueryable<?> getassetdetails(shareviewmodel item)                 {              ...               if (type == "video")                     {     if (type == "video")                     {                     return meta in my.assets().oftype<model.video>()                            join content in my.contents() on meta.contentid equals content.id                            join channel in my.channels() on content.channelid equals channel.id                            meta.id == item.id                            select new assetdetails                            {                                contenttitle = content.title,                                channelname = channel.channelname,                                ...                            };                       }                 else     {  return meta in my.assets().oftype<model.client>()                            join country in db.countries on meta.resellercountry equals country.id                                                   meta.id == item.id                            select new userandclientdetails                            {                                name = meta.resellername,                                username = meta.reselleremail,                                ..       };} 

so how decide type of iqueyable here @ runtime??

so, able verify works, i'll go ahead , post answer.

you can return iqueryable instead of generic iqueryable<>. accept iqueryable<t>. however, iqueryable, since has no direct inner type, very limited. so, you'll still need cast iqueryable<> @ other point in code done:

// piece of code know working `iqueryable<assetdetails>` iqueryable<assetdetails> assetdetails = getassetdetails(someitem); 

that's little dangerous, though, you're assuming code working , right type of thing being returned. better be:

try {     var assetdetails = (iqueryable<assetdetails>)getassetdetails(someitem);     // `assetdetails` } catch (invalidcastexception) {       // recover gracefully }
