This is how we do it in multiple steps, however same can be done in single line. var lst= new ExternalTypeCd() { ExternalIdTypeName= "ABC" , SiteCode = "DEF" } var lstt= new ExternalTypeCd() { ExternalIdTypeName= "ABC123" , SiteCode = "DEF123" } var siteExternalIdItem= new SiteExternalIdItem() { ExternalIdTypeCd=lst, SiteNumber= "1234" } var siteExternalIdItem2= new SiteExternalIdItem() { ExternalIdTypeCd=lstt, SiteNumber= "12345" } var SiteExternalIdItemArr= new SiteExternalIdItem[] { siteExternalIdItem,siteExternalIdItem2 } SiteExternalId obj= new SiteExternalId[]; obj.item= SiteExternalIdItemArr;

always use var when you use initializer as below. var lst=new ExternalTypeCd(){ExternalIdTypeName="C#",SiteCode ="DEF"}

Sachin Singh · Answer

In one line do like this var SiteExternalId = new SiteExternalId { Item = new SiteExternalIdItem[] { new SiteExternalIdItem() { ExternalIdTypeCd= new ExternalTypeCd() { ExternalIdTypeName="ABC123", SiteCode ="DEF123" } , SiteNumber="1234" }, new SiteExternalIdItem() { ExternalIdTypeCd= new ExternalTypeCd() { ExternalIdTypeName="ABC", SiteCode ="DEF" } , SiteNumber="12345" } } }

Thanks Sachin, I'm trying this way, but not success SiteExternalId = new SiteExternalId { Item = new SiteExternalIdItem[] { new ExternalTypeCd {ExternalIdTypeName = "A", SiteCode = "X"} } }, If possible could you give me initialization in a single line. Thanks Thanks a lot Sachin for your support.
