convert VB code to C#

Question

I'm a beginner in programming and i would like to know how can i translate the following code into C#

Dim arrayAlumnos(ds.Tables(0).Rows.Count - 1) As Registro

Answer 1

To preserve the array idea I'd probably write it like:

var arrayAlumnos = new Registro[ds.Tables[0].Rows.Count];

But you could say this too:

Registro[] arrayAlumnos = new Registro[ds.Tables[0].Rows.Count];

But ChaosPandion is right... a List is what you'd want to use most likely.

Answer 2

FYI, if you want to convert a lot of code from VB to C#, you can use the ILSpy disassebler. You can do this even if you don't have the original VB code. Do this:

1. Compile the VB code into a *.exe or a *.dll.

2. Open the *.exe or *.dll file in ILSpy.

3. In the language dropdown, select VB. (It's values are C#, VB, and MSIL).

Answer 3

you'll probably have a lot of one off questions like this going through your travels of conversion, might want to take a look at:

The basic idea behind the creation in C# is...

~ObjectType~ ~varName~ = new ~type~(~implement a type constructor here~);

anything in between ~~s you'll need to plug in the appropriate information. For your case it would likely be:

Registro[] arrayAlumnos = new Registro[ds.Tables[0].Rows.Count - 1];

Kind of hard since it's a different spoken language but based on your variable name i'm guessing it's an array, though as others pointed out it could easily be created as a list.

Answer 4

You should be using a list so I think this is the proper translation.

List<Registro> students = new List<Registro>();
