Problem passing structure array to another function

[stricknyn]

Hello, all, wondering if someone can tell me what I'm doing wrong here. I'm simply trying to pass a structure array to another function for some evaluation. The problem is, it hits an error when I try to pass it. I'm using VB.NET 2003. Here is my code below.

Private Structure Fields
Dim FieldName As String
Dim FieldValue As String
End Structure
'In declarations section
 
Private Sub btnAdd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAdd.Click
 
 
Dim ArrValidate() As Fields
Dim cntrl As Control
Dim X As Long
 
'Fill my array
For Each cntrl In Me.Controls
X = X + 1
ReDim Preserve ArrValidate(X)
ArrValidate(X).FieldName = cntrl.Name
ArrValidate(X).FieldValue = cntrl.Text
Next cntrl
 
'Pass the array to my function located in another class
Validation.Validate_frmProducts(ArrValidate) 'Dies here
 
end sub

Error I get is:
Z:\HTTP\ProductMgmtApp\frmProducts.vb(576): Value of type 1-dimensional 'array of ManagementApp.frmProducts.Fields' cannot be converted to '1-dimensional array of System.Object' because 'ManagementApp.frmProducts.Fields' is not a reference type.


Anyone know what I'm doing wrong? Thanks in advance

The error message is fairly explicit. The method argument is an Object array and you are passing a Fields array. There is no valid conversion between the two because Fields is a structure and therefore a value type. You will either need to make Fields a class so it is a reference type and the conversion is therefore valid, or else put your Fields objects in an Object array instead of a Fields array.
