C# problem - Reading and adding from file

JohnCleary

I'm doing a little practise before my exams in 2 weeks.

Basicly, im writing a program that reads info from a file and displays it on screen, nice and simple.

Now, lets say I have the following situation
Name Sales Comission
John 50 5
Mary 100 10

Now, ive gotten the info from the file using field[0], field[1] etc....

BUT, how would I go about Adding the total sales together? Any help much appreciated! (Or a link to info on the web!)

Why not as you read in a record you read each into an array of strings called field like you suggested. Then add name's to a string array, sales to an int array and commission to an int array.

Something like this

string [] field = new string [ 3 ] ;
ArrayList names = new ArrayList ( ) ;
ArrayList sales = new ArrayList ( ) ;
ArrayList commision = new ArrayList ( ) ;

while ( records to read )
{
  //... Read in record 
  names.Add ( field [ 0 ] ) ;
  sales.Add ( field [ 1 ] ) ;
  commision.Add ( field [ 2 ] ) ;
}

int total_sales = 0 ;
for ( int i = 0 ; i < sales.Count ; i++ )
   total_sales += (int)sales [i] ;
