    Get a random number of relations

    Hi Guys,

    Does anybody knows how I can achieve this:

    I have this line of code, where I getting all relations that a country has with a category:

    umbraco.cms.businesslogic.relation.Relation[] categoryRelations = umbraco.cms.businesslogic.relation.RelationType.GetByAlias("categoryToCountryRelation").GetRelations(countryId);

    Now, I need not to get all relations , but only 4 random.

    Does anybody know how I can dot his please?

    Thank you.

    Hi you can use the linq functionality to fetch random from the list.

    e.g 

    List<umbraco.cms.businesslogic.relation.Relation> NewRandomRelList = YourList.OrderBy(x => System.Guid.NewGuid()).ToList().Take(4);

    So in your case

    List<umbraco.cms.businesslogic.relation.Relation> NewRandomRelList = categoryRelations.OrderBy(x => System.Guid.NewGuid()).ToList().Take(4);

    Hope it helps.

    LUV umbraco!

    Hi jigar,

    Thank you for your reply.

    But with the first line of code, 

    umbraco.cms.businesslogic.relation.Relation[] categoryRelations = umbraco.cms.businesslogic.relation.RelationType.GetByAlias("categoryToCountryRelation").GetRelations(countryId);

    I am even getting all the relations, and the selection of the four random is being done after this call. So in the array, I am also getting all relations, even the uncessary.

    May I choose the four random in this line of code where I am getting the relations?

    Thank you.

    Kind Regards.

    yes you can product the one liner for sure, I was trying to give the quick direction.

    It should look like 

    umbraco.cms.businesslogic.relation.Relation[] categoryRelations = umbraco.cms.businesslogic.relation.RelationType.GetByAlias("categoryToCountryRelation").GetRelations(countryId).OrderBy(x => System.Guid.NewGuid()).ToList().Take(4);

    Hope it help.

    Luv Umbraco!!!
