Implicit conversion

Question

Hello,

I've converted a C# project to VB (using a tool - I don't know C#) and my converted project has 4 warnings.

2 are warning BC42016: Implicit conversion from Long to Integer for the below 2 lines:

Source C#:
byte[] buffer = new byte[Stream.Length];
VB:
Dim buffer(Stream.Length - 1) As Byte

Source C#:
For i As Integer = 0 To Header.UIntegerNumber - 1
VB:
for (int i = 0; i < header.UIntegerNumber; i++)

2 are warning BC42016: Implicit conversion from Decimal to Long and Long to ULong for this line:

Source C#:
h = (h * 16777619) ^ buffer[i];
VB:
h = (h * 16777619) Xor buffer(i)

Source C# project does not show warnings, while converted VB shows the above 4 warnings.

How do I get rid of warnings to be able to have option strict on?

Thanks for help :)

Hi @Peter Volz ,

You can try the following code.

Override an implicit type conversion to an explicit type transformation.

Or choose to be compatible with more types of constructors.

        Dim buffer As Byte() = New Byte(CInt(Stream.Length) - 1) {}

        For i As Long = 0 To Header.UIntegerNumber - 1

        Next
        h = CDec((h * 16777619)) Xor buffer(i)

Best Regards.
