i have a comma separated string of numbers inside of a var named num_str
the contents of num_str looks like this: "1,2,3,4,5" etc
i am looking for a way to add num_str to an expression to convert the sting of numbers contained therein to an array of integers
i want to make sure i can simply reference 'num_str' to get the numbers from instead of spelling it out like {"1,2,3,4,5"}
i have tried this, where 'num_str' contains the numbers
Dim test As String = Nothing Dim result() As Integer = Int32.TryParse(num_str.Split(","c)) For i = 0 To result.Length - 1 test += result(i) Next
but that doesn't work
what i am looking for is a result with an array of numbers
Dim totalValue = str. Split(","c). Select(Function(n) Integer.Parse(n)). Sum()
Try this to create integer array
Dim numbers = str.Split(","c).[Select](Function(n) Integer.Parse(n)).ToList()
Then you can use the loop you are using at the moment to append value to string
You can do it like this:
Dim num_str As String = ... Dim str() As String = num_str.Split(",") Dim result(str.Length - 1) As Integer For i = 0 To str.Length - 1 result(i) = str(i) Next
I was just working on this for a client, and I found an elegant little piece of code that will replace your single string value and effectively convert it to integer (or more precisely "double") very easily, and can be used for "find and convert" just as easily. I wrote a bunch of these into a GPA calculator that changes the letter grade entered into the GPA number format for math conversion and display without anything else but these three lines and a little loop.
For m = 0 To UBound(myArray) myArray(m) = Replace(myArray(m), "thisstring", 0.0) 'integer 0.0 can be any Next m
