Just like the title says; I want to use something like Mid(*stringName*, *startIndex*,[*integerLength*]), but instead of the third argument taking a string length, I want it to take the end character index. So in an example like *this*

```
alphabet = "ABCDEFG"
partial = *method I want to use*(alphabet, 2, 4) 'partial would equal "BC"

```

(Forgive me if my index numbers are off, but I hope you get my point.)

Does something like this exist in VB.NET?
