I hope by "Visual Basic" you mean VB.NET, because everything else related to the word "Basic" does not even worth mentioning.
What samples? You don't need any samples if you already have C# code. You can automatically and reliably and easily translate any project to VB.NET or to C#.
Please see my past answers:
Code Interpretation, C# to VB.NET[
^],
Need to convert vb code to c#[
^].
To translate the whole project, use open-source ILSpy. My answers referenced above explains how to do it in sufficient detail.
And do be serious: if you want to get some help on .NET, you need to understand at least some C#. With VB.NET along, you cannot find too much.
