In my example below, none of the ViewState, Session or Request Params (arrays) have their round brackets converted to square brackets.

Example:
Protected Property CurrentSortColumn() As String
Get
If (ViewState("SortColumn") <> Nothing) Then
Return ViewState("SortColumn").ToString()
Else
ViewState("SortColumn") = "ADD_BOOK_ID"
Return "ADD_BOOK_ID"
End If
End Get

Set(ByVal value As String)
ViewState("SortColumn") = value
End Set

End Property

Private Sub Test

ParentControlID = Request.Params("ParentCtlID")

If DirectCast(Session("USER_TOKEN"), Int32) > 0 Then
UserCanEditAddBook = True
End If

End Sub

I've encountered a problem removing an event handler converting c# to VB (2008)

c# code:

void displayElement_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
VerifyEditVisualization(sender);
}

void displayElement_GotFocus(object sender, RoutedEventArgs e)
{
VerifyEditVisualization(sender);
}
.
.
.
.

foreach (FrameworkElement fe in _displayControls)//don't hang on to controls via event handlers
{
fe.GotFocus -= displayElement_GotFocus;
fe.MouseLeftButtonDown -= displayElement_MouseLeftButtonDown;
}

generated VB:

Private Sub displayElement_MouseLeftButtonDown(ByVal sender As Object, ByVal e As MouseButtonEventArgs)
VerifyEditVisualization(sender)
End Sub

Private Sub displayElement_GotFocus(ByVal sender As Object, ByVal e As RoutedEventArgs)
VerifyEditVisualization(sender)
End Sub

.
.
.
.
For Each fe As FrameworkElement In _displayControls
'don't hang on to controls via event handlers
fe.GotFocus -= displayElement_GotFocus
fe.MouseLeftButtonDown -= displayElement_MouseLeftButtonDown
Next

Here is one suggestion/bug report. VB to C# converter neglects/ignores indexers

Example:

C#:

private void IndexerUsageExample()
{
string[] someValues = new string[] { "A", "B" };
string value = someValues[1];
}

Covert to VB: (so far so good)
Private Sub IndexerUsageExample()
Dim someValues() As String = New String() {"A", "B"}
Dim value As String = someValues(1)
End Sub

Convert back to C# (Ouch!)

private void IndexerUsageExample()
{
string[] someValues = new string[] { "A", "B" };
string value = someValues(1);
}
The bug is in the usage of the indexer. C# uses square brackets for indexers and converter didn't "detect" that it is an indexer. I am not sure how easy it is to detect, but it would be awesome to actually have that functionality. I can say at least for myself that I do use this type of syntax very often.

Add support for a variety of VB string functions:

1. Convert LCase and UCase to ToLower and ToUpper
2. Convert Left, Mid, and Right to Substring
3. Convert LTrim, RTrim, and Trim convert to TrimStart, TrimEnd, and Trim
4. Convert InStr to IndexOf
5. Convet Len to Length
6. Convert Replace to Replace

First of all let me say that this tool is very good and useful especially as a web page, but there are a few things that I think are not right
and sometimes the code converted is not compiling or does not follow C# idiosyncrasies.

Dim newDTRow As DataRow
Dim dtEmployeeEarnings As New System.Data.DataTable
Dim CurrencyFormatString As String = "##,###,##0.00;(##,###,##0.00)"
newDTRow("CurrentHours") = IIf(IsDBNull(dtEmployeeEarnings.Rows(i)("NumHours")) OrElse dtEmployeeEarnings.Rows(i)("NumHours") = "0.0", "", Format(dtEmployeeEarnings.Rows(i)("NumHours"), CurrencyFormatString))

DataRow newDTRow = default(DataRow);
System.Data.DataTable dtEmployeeEarnings = new System.Data.DataTable();
string CurrencyFormatString = "##,###,##0.00;(##,###,##0.00)";
newDTRow("CurrentHours") = (Information.IsDBNull(dtEmployeeEarnings.Rows(i)("NumHours")) || dtEmployeeEarnings.Rows(i)("NumHours") == "0.0" ? "" : Strings.Format(dtEmployeeEarnings.Rows(i)("NumHours"), CurrencyFormatString));


1. String formatting should to String.Format and not Strings.Format
2. Collection index access should be []:
dtEmployeeEarnings.Rows(i)("NumHours") should be dtEmployeeEarnings.Rows[i]["NumHours"]
3. Imposing importing Microsoft.VisualBasic and then using Information.IsDBNull in order to convert IsDBNull
is not really how a C# developer would go about writing this code. I personally would rather see something else
even if as simple as " ... == System.DBNull.Value "
