VB 2008: Help instantiating an array of objects

[Glupii]

I am trying to Instantiate (did I spell that right?) and dimension an array of objects but I keep getting a NullReferenceException not handled error telling me to use the "new" keyword to create an object instance. This only happens after the loop has gone through one iteration meaning it is on the second element of the array that it throws this error. Here is my code:

        Dim objProvider(50) As ClientHospital
        objProvider(0) = New ClientHospital()
        Dim ClientReader As SqlDataReader
        Dim ClientCount As Integer
        Dim I As Integer = 0
 
        'Load array
        ClientReader = GetClientInfo()
        If (Not ClientReader Is Nothing) AndAlso ClientReader.HasRows Then
            Do While ClientReader.Read
                'Initialize obj properties
                objProvider(I).ProviderID = ClientReader("ProviderID")
                With objProvider(I)
                    .ProviderID = ClientReader("ProviderID")
                    .SysID = ClientReader(1)
                    .Name = ClientReader(2)
                    .Processed = False
                End With
                lstProviders.Items.Add(objProvider(I).Name)
                I = I + 1
            Loop
        End If
 

Does anyone see what I am doing wrong? I have been banging my head against this wall all day. HELP!

well im sorry, but i dont have the answer to your question, but you may find it more relevant to post this question under the correct forum such as .NET forum, which visual basic 2008.net is part of the .net framework. perhaps a moderator can move this thread.

I think the problems is that you have only instantiated the first object in your array. that is objProvider(0) = New ClientHospital()

Try making a loop like
for i as integer = 0 to 49
objProvider(i) = New ClientHospital()
next

Hi,

Remove this line:
objProvider(0) = New ClientHospital()

Immediately after "DO"
write this line:

objProvider(i) = New ClientHospital()
objProvider(I).ProviderID = ClientReader("ProviderID")
...
