Converting vb.net to c#

[linuxjr]

I haven't tried this one yet Batch Code Converter[^] but I have used the single file vb to c# converter Single File Code Converter[^] and it works pretty decently. I hope this helps some.

I used developer fusion's online tool to convert a VB.Net website to c#. Free, but does not like "handles" clauses. http://www.developerfusion.com/tools/convert/vb-to-csharp/[^] Everything else seemed to be ok.

I highly recommend Instant C#. It's not free but worth every penny, it's very accurate and we just used it to convert 10,000s of lines of VB.NET to C#. http://tangiblesoftwaresolutions.com/Product_Details/Instant_CSharp.html[^]

SharpDevelop has a converter feature built in. Appears to just call this webservice for the actual conversion... so try before you download.

I have had success with the CSharpener product, but I don't think it was free. Plus you must fix numerous syntax errors after the conversion process.

You can try the below online tools http://www.developerfusion.com/tools/convert/vb-to-csharp/[^] and http://www.carlosag.net/Tools/CodeTranslator/[^]

http://converter.telerik.com has a bulk file converter tool too. i have used that extensively over the last few years on various projects and works well. just the indexers that you have to do manually, and the last time i used it it didnt like LINQ

Try with http://download.cnet.com/Convert-NET/3000-2096_4-10696573.html[^] It occasionaly hickups, but all in all it is dependable.

How about rewriting it from the start in C#? Im not really in favour of these conversion tools as all they do is a straight port and can add a bit of baggage on the way. if you rewrite it you can optimise it more for the new language, and possibly increase performance. personally, if you just want to translate from vb to c# without rewriting or adding new features then I would question the need of doing this task in the first place.

I can vouch for the Telerik tool. This is the most effective (free) converter I have used. Still don't understand why it can't work out that C# uses square brackets for indexers and VB.NET uses normal brackets. I always have to fix these manually. Also watch out for array declaration. In C# you declare an array according to the number of items in it, in VB.NET you specify the upper boundary. This can cause difficult to find run-time errors if you don't look out for it.

So would I. IMO all .NET developers should be able to read code reasonably well (and look up the little bits they don't understand) in both C# and VB regardless of which they code in.

SharpDevelop can convert whole projects in one step. And yes, while it does make errors; I think it does pretty good job nowadays. For example, SharpDevelop 3.1 RC2 correctly converts the different rounding semantics when casting floating-point values to integers (VB rounds, C# truncates). Most other converters just translate "CInt(x)" to "(int)x", introducing a subtle bug in the converted program if x was a floating-point value.

The converter built into SharpDevelop does not call any webservice. SharpDevelop and that webservice just use the same open-source libraries to do the conversion (ICSharpCode.NRefactory and ICSharpCode.SharpDevelop.Dom).

Thanks, I wasn't aware of that. I'll have to look at the latest version.

To convert VB normal brackets to square brackets, the converter needs to know if the expression is referring to a method or an array. Of the free code converters I know, only SharpDevelop uses type information. Note that type information isn't only necessary to translate array access correctly - it also is required to distinguish integer divisions from other kinds of divisions; the different sorts of cast operators, etc. Converters which don't use a type system will introduce subtle bugs in the translated code because the two languages work differently (e.g. int a=3, b=2; int c=a/b; results in c=1 in C#, but c=2 in VB. The converter must detect that the division is an integer division and use the VB integer divide operator '\') By the way, I highly recommend downloading SharpDevelop to do the conversion. The online converter[^] cannot look at your project's references, so it cannot use the full type system.

Since you are planning on "down grading" your code to C# [:-) I program in both languages fluently] here is the best online free tool I have found... http://www.developerfusion.com/tools/ Beyond this most such tools cost around $200.00 or so... VB.NET!!! Still The One!!!

The Telerik Converter is quite useless. I Tested it with 3 perfectly well running .vb files, leaving out the handles-clause and I always got the same type of error: CONVERSION ERROR ... invalid StructMembDecl.
