Converting VB.NET code to C#

Question

I have the follwing VB.NET code I am trying to convert to C#.

Dim decryptedBytes(CInt(encryptedStream.Length - 1)) As Byte

I tried this:

int tempData = Convert.ToInt32(encryptedStream.Length - 1);
Byte decryptedBytes;
decryptedBytes = decryptedBytes[tempData];

But got this error message:

Cannot apply indexing with [] to an expression of type byte.

Please note that the VB.NET code works.

Using the SharpDevelop code converter, the output for your VB code is:

byte[] decryptedBytes = new byte[Convert.ToInt32(encryptedStream.Length - 1) + 1];

Note that VB specifies for upper bound of the array where C# specifies the length, so the converter added the "+ 1".

I would simplify that to:

byte[] decryptedBytes = new byte[(int)encryptedStream.Length];

You can probably remove the (int) cast, too. I'll be very surprised if the Length property here isn't already an int.

Documentation disagrees with you: public int Length { get; } and Type: System.Int32 : msdn.microsoft.com/en-us/library/…

@R. Bemrose: System.IO.Stream, not String.

byte[] decryptedBytes = new byte[(Int32)encryptedStream.Length];

By the way if you have further problems try this:

DeveloperFusion is using an old version of the SharpDevelop code converter (NRefactory). Better use codeconverter.sharpdevelop.net/SnippetConverter.aspx. For example, the cast to int would have subtly different behavior than the original VB code if the Length property returned a double - this is why never versions of the converter use Convert.ToInt32().
