I am trying to add a value to an array by converting it to a list
Dim oItemSubmit As InventoryService.InventoryItemSubmit
Dim oAttInfo As New InventoryService.AttributeInfo
oAttInfo.Name = "FeatName"
oAttInfo.Value = "value"
oItemSubmit.AttributeList.ToList().Add(oAttInfo)
AttributeList is an array on AttributeInfo. But the code doesn't seem to work. Any ideas
Thanks Jothish
AttributeList.ToList() is making an copy, and you are inserting into copy, not into original array
You can use Concat to add element or sequence
C# sample
oItemSubmit.AttributeList = oItemSubmit.AttributeList.Concat(new []{oAttInfo}).ToArray();
oItemSubmit.AttributeList.ToList().Add(oAttInfo)
is adding the element to a temporary list which is created and then not used.
You need to store the reference and then add to it:
Dim myList as List<MyType>
myList = oItemSubmit.AttributeList.ToList()
myList.Add(oAttInfo)
The oItemSubmit.AttributeList.ToList() call creates a whole new instance of List(Of AttributeInfo) class, which has nothing to do with the original array other than that it contains items from it. Adding items to it will not add items to said array.
Try this,
oItemSubmit.AttributeList = theNewList.ToArray
