c# - Populate object from list of objects -


i have following rootobject object need populate.

public class document2 {     public string homecommunityid { get; set; }     public string repositoryid { get; set; }     public string documentuuid { get; set; }     public string doctype { get; set; } } public class document {     public document2 document { get; set; } }     public class rootobject {     public list<document> documents { get; set; } }

i need populate rootobject object list of following documentquery object. 

public class documentquery {         public string doctype { get; set; }         public string homecommunityid { get; set; }         public string repositoryid { get; set; }         public string documentuuid { get; set; }  }

i trying follows:

rootobject doc = new rootobject()    {       document= obj.select(s => new document()       {           document = new document2()              {                  doctype = s.doctype               }        })     };

i need able json in format:

    {   "documents": [     {       "document": {         "homecommunityid": "",         "repositoryid": "",         "documentuuid": "",         "doctype": ""       }     }   ] }

you can use following code, if don't want play reflection etc.:

list<documentquery> queries = new list<documentquery>(); // fill queries rootobject root = new rootobject(); foreach(var query in queries) {     document document = new document()     {         document = new document2()         {             homecommunityid = query.homecommunityid,             repositoryid = query.repositoryid,             documentuuid = query.documentuuid,             doctype = query.doctype         }     }     root.documents.add(document); }

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
