How to get integers from a string?

• Vaish

  one way would be to go through each character, check if its a number, if so, add it to a collection or something.

  Dim theNumbersOnly as new System.Text.StringBuilder()

  for each currentChar as Char in theString

     if Char.IsNumber(currentChar) = true then

        theNumbersOnly.Append(currentChar)

     end if  

  next

   

  theString being the string that contains the letters/numbers

  if the space is neccessary then you can alter the solution a bit to include the space:

  for each currentChar as Char in theString

  if Char.IsNumber(currentChar) = true Or Char.IsWhiteSpace(currentChar) then

  theNumbersOnly.Append(currentChar)

  end if

  next

  or you could:

  Or currentChar.Equals(' ')

  instead of "Or Char.IsWhiteSpace(currentChar)"
