c# - Reading a text file: 'If' character store information after character -

-

Everything I am trying to read is read in a text file that keeps all the data related to the portion of the car Such as weight, acceleration, top speed etc. I just want to be able to write in the text file: W5A10T20

So I have to check if there is a character and if so, the value then This is what I've been trying so far:

Public Virtual Zero Reidstate (String Choice Model) {List line = New list (); Using 

  (var ModelInfo = new FileStream (Selected Model, FileMode.OpenOrCreate)) {{StreamReader Reader = New StreamReader (ModelInfo)} {float input; String line = reader Readline (); Save the value after ({line = reader. Redline ())! = Null () (if (line wires ("w")) {// after the character.}}}}}   
 For some reason this is not even getting 'W' character in 'if' for some reason besides how I will have to go about grabbing the price after the character.  
 Thank you.   
 
 
 For any reason, you are not using substrings?  
  var test = line.substring ("w")   
 call it your blu Keep a. / P>

Setting Variables Create another conversion for (you can not do it in the same conversion Uses): set variables element variable: The element that reads / writes your data creates a new connection and sets the connection parameter using $ {variable name_} Note that you will need to type in the field field in the field $ {password} Also keep in mind that this can be a security problem as the

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ...

Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
