Convert Decimal to Ascii? - vb.net

Question

this is how to convert decimal to Ascii, but i have decimal in defferent format, and i want ot convert it to ascii.
Public Shared Function DecimalToASCII(dec As String) As String
Dim ascii As String = String.Empty
For i As Integer = 0 To dec.Length - 1 Step 3
ascii += CChar(ChrW(Convert.ToByte(dec.Substring(i, 3))))
Next
Return ascii
End Function
EX:
This is in Decimal and i want ot input it in textbox1.text:
"912,697,583,1065,261"
and i want to do operation to each group of numbers between comma and then convert it to Ascii???

Answer 1

To split the string into groups, you can just use the Split command. Your code is a long winded way of doing this - although it will fall over when it tries to deal with the four digit number.
Create a string array with no predefined number of elements like this -
Dim myArray()
Populate it with this code
myArray = Split (dec,",")
So now, using your input example, your ascii string array contains this data
myArray (0) = "912"
myArray (1) = "697"
myArray (2) = "583"
myArray (3) = "1065"
myArray (4) = "261"
If you want to have numbers that you can use in arithmetic operations, use this code instead. The function assumes that you're using integers, but if you want to use another type, just change all the occurrences of Integer to the type you want to handle, and change the CInt function to CDbl or cSng.
Public Shared Function DecimalToASCII(dec As String) As Integer()
'create an array of strings
Dim ascii() As String
'split each group into the array
ascii = Split(dec, ",")
'declare numbers array that is the same size as the ascii array
Dim numbers(ascii.GetUpperBound(0)) As Integer
'convert the array of strings to an array of numbers
For i As Integer = 0 To ascii.GetUpperBound(0) - 1
numbers(i) = CInt(ascii(i))
Next
'return an array of numbers containing each group
Return numbers
End Function
Use it like this
Dim dec As String = "912,697,583,1065,261"
Dim MyNumbersArray() As Integer = DecimalToASCII(dec)
With this code, you will have an array of Integers like this
MyNumbersArray(0) = 912
MyNumbersArray(1) = 697
MyNumbersArray(2) = 583
MyNumbersArray(3) = 1065
MyNumbersArray(4) = 261
Now you can perform whatever math you want using the array elements.
