comparing data in csv files and doing calculations, multiplying double numbers and ge

[HeshamTaha]

I have a csv file that has these values

MobileId;MenuTr eeView;MenuName ;MenuInfo;MenuA ction

1002;BTT_Menuba um;TS:Coord;22% 71%:0:0;TouchSc reen

1002;BTT_Menuba um;"Open bookmark";0;Wai t

1002;BTT_Menuba um;T;T;PressKey

If it found TouchScreen in the MenuAction Column it does the following multiply the value of 22 by length/100 and the value 71 by width/100. in the MenuInfo Column. and return the answer in x and y knowing that I have the length as a double List in another method and the width also..

second case if It found PressKey Value in MenuAction Column. It gets the X, Y for the Letter T in the MenuInfo from a second csv file which has this data

intKeyID;intMob ileID;strTasten _Name;strTasten funktion;strDru ckrichtung;dblX ;dblY;dblZ;;;
17999;1002;E;Ma ndatory;mitte;-20;-10;27.74;0;0;0
18000;1002;R;Ma ndatory;mitte;-20;-10;27.74;0;0;0
18001;1002;T;Ma ndatory;mitte;-20;-10;27.74;0;0;0
18002;1002;Z;Ma ndatory;mitte;-20;-10;27.74;0;0;0

and also save it in X and Y

What i did so far is

if(MenuActionList.Contains("TouchScreen")){
   string a = MenuInfoList[i];
   string [] x = a.Split(new char [] {'%'});
   double Xcsv = Convert.ToDouble(x[0]);
   double Ycsv = Convert.ToDouble(x[1]);
   List<double> W;
   List<double> K;
  GetLengthWidth(MobileID, out W, out K);
// Knowing that this calls the List Length and //Width            
                        
}   
else{
   if (MenuActionList.Contains("PressKey")){
      StreamReader MT = File.OpenText(@"C:\Robotron\Execution\MenuTree.csv");
      StreamReader TT = File.OpenText(@"C:\Robotron\Execution\Tastatur.csv");
      string line6;
      string line7;
      while ((line6 = MT.ReadLine()) != null)
      {
         string[] fll = line6.Split(';');
         string []fl = line7.Split(';');
         if (fll[3] == fl[2]) continue;
       
         // should get x,y,z
      }

The question is how do i multiply the double with the length in the first if condition andin the second if condition how can i get the corresponding data from the second csv?.. Thanks in advance
