Maybe a DataTable will do it for you....
Dim dt As New DataTable
dt.Columns.Add("Source")
dt.Columns.Add("Input")
Dim arr1() As String = {"TEST1", "input1"}
dt.Rows.Add(arr1)
Dim arr2() As String = {"TEST1", "input2"}
dt.Rows.Add(arr1)
Dim arr3() As String = {"TEST1", "input3"}
dt.Rows.Add(arr1)
Dim arr4() As String = {"TEST1", "input4"}
dt.Rows.Add(arr1)
Dim arr5() As String = {"TEST2", "input5"}
dt.Rows.Add(arr1)
Dim arr6() As String = {"TEST2", "input6"}
dt.Rows.Add(arr1)
'Loop through each of the records for TEST1
For Each dr As DataRow In dt.Select("[Source] = 'TEST1'")
'what ever
Next
Sorry, just realised you want to store an Exception object. Is the second field unique? If it is, use a HashTable and use the second field as the key, with the other field as the value. To filter out the first column, do something like this....
For Each v As Object In ht.Values
If v = "ITEM1" Then
'whatever
End If
Next
...where ht is the original HashTable.
Regards,
Wayne
how am I gonna make this code work. The error in the data table is either
of type exception or of type string here is the code I wrote but it need HELP!
For Each dr As DataRow In organizedErrors.Select("[S
Dim type As String = dr.GetType.Name
If type = "Exception" Then
'These lines need dr to be casted as typr exception somehow
txtTestResults.Text = txtTestResults.Text & "The code broke " & dr.StackTrace & vbCrLf
txtTestResults.Text = txtTestResults.Text & dr.Message
ElseIf type = "String" Then
txtTestResults.Text = txtTestResults.Text & dr.ToString
End If
Next
Disregard the last 2 snippets:
I got foreach wrong in this one for starters and I dont know if my cast to type
exception is gona fly....
For Each dr As DataRow In organizedErrors.Select("[S
Dim type As String = dr.Item("Error").GetType.N
If type = "Exception" Then
Dim ex As Exception = CType(dr.Item("Error"), Exception)
txtTestResults.Text = txtTestResults.Text & "The code broke " & ex.StackTrace & vbCrLf
txtTestResults.Text = txtTestResults.Text & ex.Message
ElseIf type = "String" Then
txtTestResults.Text = txtTestResults.Text & dr.ToString
End If
Next

That is a little vague - what is the purpose?
the problem is that you can store either but would need to make the variable an object and use gettype to figure if its a string or not.
if you make a class that has a property of each and maybe a boolean prop of HasErros or somthign.
