Dim b(b1.Length + b2.Length - 3) As Byte

Mark suggested:
VB Dim b(b1.Length + b2.Length - 3) As Byte Converted C# byte[] b = new byte[b1.Length + b2.Length - 2]; Why is it changing my math? I've been using this converter to teach myself C#. Great tool.

Cannont convert Nullable property using ?

2012-02-02T10:12:38-08:00

Kyle Schultz suggested:
When trying to convert from VB.Net to C# (or vice versa), if you have a nullable property that is created using the ? and not Nullable<> the post back on your page is not ready correctly. Public Property CurrentDate As DateTime? I should be able to pass that and get public DateTime? CurrentDate { get; set; }

I have a problem converting this code:

Gromhelm suggested:
public static readonly DependencyProperty ProgressProperty = DependencyProperty.RegisterAttached("Progress", typeof(double), typeof(ViewportAnimation), new PropertyMetadata(0.0, new PropertyChangedCallback(delegate(DependencyObject o, DependencyPropertyChangedEventArgs e) { ((ViewportAnimation)o).ProgressChanged(e); }))); VB.Net Converter gives me this: Public Shared ReadOnly ProgressProperty As DependencyProperty = DependencyProperty.RegisterAttached("Progress", GetType(Double), GetType(ViewportAnimation), New PropertyMetadata(0.0, New PropertyChangedCallback(Function(o As DependencyObject, e As DependencyPropertyChangedEventArgs) Do DirectCast(o, ViewportAnimation).ProgressChanged(e) End Function))) There seems to be a problem converting the function, but I don't know how to solve it.

Add Intelligence to code conversion to weed out common errors and peculiarities

2011-07-01T02:59:23-07:00

Vaibhav Garg suggested:
There are multiple special cases where hard logic cant decide which way to go. e.g: 1. Array variables, Known properties like ViewState, Session etc Current: Request.QueryString("key") -> Request.QueryString("key"); Correct: Request.QueryString("key") -> Request.QueryString["key"]; 2. Optional brackets in VB methods are not so optional in C# Current: myvar.ToString -> mycar.ToString; Correct: myvar.ToString -> mycar.ToString(); 2. Char literals Current: If "hello"(0) = "h" Then : End If -> if("hello"[0] == "h") { } Correct: If("hello"(0) = "h") Then : End if -> if("hello"[0] == 'h') { } and other similar peculiarities.. There could be a variety of solutions, specially for known .Net properties/items like ViewState etc where you can reflect on and identify the type etc. You can also keep track for declarations to identify the type of a item so that correct conversion can be done, known array types for example. There can also be a advanced settings mode to the converter, where a user can specify known array types for example. These attempts at intelligence can be controlled via the settings so that the User can decide it is it good for them or not. I would also love the ability to specify my own custom code that would be run after/before conversion, sort of like creating onBeforeConvertion and onAfterConvertion events. Here the user can specify their own logic like regex, search-replace and other code that you deem safe. Most of this is probably overkill but I am just thinking out loud so thanks for you patience in reading this. You tool has helped me a lot over the years and I have seen it grow. Thanks

ViewState, Session or Request.Params not arrays [updated]

2011-07-01T02:33:42-07:00

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

Linq Query from C# to VB [updated]

2011-06-30T07:08:40-07:00

Here's an example from Microsoft's Tailspin Spyworks tutorials that translates very poorly. ============ var query = (from ProductOrders in db.OrderDetails join SelectedProducts in db.Products on ProductOrders.ProductID equals SelectedProducts.ProductID group ProductOrders by new { ProductId = SelectedProducts.ProductID, ModelName = SelectedProducts.ModelName } into grp select new { ModelName = grp.Key.ModelName, ProductId = grp.Key.ProductId, Quantity = grp.Sum(o => o.Quantity) } into orderdgrp where orderdgrp.Quantity > 0 orderby orderdgrp.Quantity descending select orderdgrp).Take(5); ======== If you run the convertor on this, you'll find several statements that merge together, "select" disappears entirely and whatever was on either side of it merges into a single word, "equals" turns into "=", and many other bizarre things happen.
