For Each Loop

Question

Guys

Im having real problems getting my head around foreach loop

I have the following

     var readLine = await FileIO.ReadLinesAsync(sampleFile);
foreach (String i in readLine)
     {
         string[] Split = readLine[i].Split(new Char[] { ',' });
this.textoutput.Text = Split[0];
     }

readLine is a string loaded from a CSV file and has 1295 []

I need to loop through each string in the array, split it, check the first part and print it in a text box

I get two errors with the code

1. The best overloaded method match for 'System.Collections.Generic.IList<string>.this[int]' has some invalid arguments

2.    Argument 1: cannot convert from 'string' to 'int'

both on the readLine[i] part of the split line

any ideas where i'm going wrong

Answer 1

In your foreach the "i" variable is a string, not an indexer into the array of strings. Instead of

readLine[i].Split(new Char[] { ',' });

do i.Split...

i.Split(new Char[] { ',' });
