I have a byte array need to convert to integer, and this array only have one value. I tried Bitconverter, convert.ToInt32 both are not working for me. my code as follows:
Dim a As new Byte() ={&H1C} ' the value range is {&H01} to {&HFF}
Dim key As integer = BitConverter.ToInt32(a,1)
I need the result with key = 28, which convert function I should use? Thank you very much.
BitConverter.ToInt32 needs 4 bytes to work with, so you just need to put your one byte value into a 4 byte array. Allowing for the endianness, something like this:
Dim a() As Byte = { &H1C }
Dim b(3) As Byte
If BitConverter.IsLittleEndian Then
b(0) = a(0)
Else
b(3) = a(0)
End If
Dim key As Integer = BitConverter.ToInt32(b, 0)
You are not converting an array of values, but rather a single array element.
That said, there is no need to call a conversion function to convert a single Byte to an Integer. Just assign the value.
Dim key As Integer = a(0)
