Some upgrades for the VS code convertor

I converted several hundred thousand lines of code from VS to C# using the online tool - glutton for punishment I guess! I found a couple of problems that I think might be easy to fix that would eliminate 70% of the problems I saw.

1) In VS you can have functions with no inputs - subs. There are many common ones, like .ToString(), .ToUpper(), etc. VS demands you leave off the parens in these cases, but C# demands them. The converter fails to notice these and so I have to manually add "()" to thousands of lines of code.

2) VS uses parens for enumerators, like MyList(1). C# uses braces for enumerators, like MyList[1]. The converter doesn't convert these. VERY annoying!

3) The convertor ignores #if #else #endif, and so it sees both halfs of the code. So if you have an End Sub in an if block, for instance, it can't convert it because it sees two End Subs. Suggest commenting out the one that is not active, or if that's not obvious, leaving the first active and commenting out all the ELSE side of things.

watcher.changed += new filesystemeventhandler(addressof watcher_changedcreationtime) ====>> addhandler watcher.changed, new filesystemeventhandler(addressof watcher_changedcreationtime)

I'm tried convert from C# to

in file Watcher.cs

VB.NET (VS2013, .NET4.0) C# to error is:

watcher.changed += new filesystemeventhandler(addressof watcher_changedcreationtime)

VB.NET (VS2013, .NET4.0) correct is:

addhandler watcher.changed, new filesystemeventhandler(addressof watcher_changedcreationtime)

Error converting VB AND / OR operators to C#

When converting a VB IF-THEN statement, sometimes the conditional AND and OR operators are converted to '&' and '|' respectively. These are bit-operators, not boolean operators. Expecially when the exact type cannot be determined, the bit opertors are favoured over the move obvious '&&' and ||' boolean operators.
If x.boolField And y.Length > 1 Then
' do something
End If
if (x.boolField & y.Length > 1) {
// do something

Structure to struct

Public Structure Oid
Public Shared Property RuntimeMac As String = ""
Public Shared Property UnitMac As String = ""
End Structure

gets converted to

public struct Oid
public static string RuntimeMac { get; set; }
public static string UnitMac { get; set; }

instead of

public struct Oid
public const string
RuntimeMac = "",
UnitMac = "";

array length in array initialiser is different from C# to VB.NET

object[] namevalues = new object[2 * parms.Length]; in C#

Converts to:

Dim namevalues As Object() = New Object(2 * parms.Length - 1) {} in VB.NET

Note the -1 in the array length

Incorrect conversion for implemented interfaces

The c# to vb converter does not add the "Implements Interface.Mehod" after the implemented method for example:
When implementing IXmlSerializable the "Implements IXmlSerializable.GetSchema" was not added after the "Public Sub ReadXml(reader As System.Xml.XmlReader)"

Bug no number truncation from C# to VB .net

Tried to convert some code from C# to VB .net using your online converter but it translated the code wrong and does truncate the number down.

It tried to translate this C# code:-
return (int)(Sample()*maxValue);

And turned into this VB code:-
Return CInt(Sample() * maxValue)

The problem is the CInt function in VB does not truncate a number down, so if you had a value of 9.98 the CInt function would will return 10. But the C# cast of (int) only rounds down so should return 9 not 10. CInt is mainly used to convert text to a number. You need to use Floor or Fix functions to address this issue.

Please can you fix this bug?
