I am using the below code to read data from a text file row by row. I would like to assign each row into an array. I must be able to find the number or rows/arrays and the number of elements on each one of them.
I would also like to do some manipulations on some or all rows and return their values.
I get the number of rows, but is there a way to to loop something like:
*for ( i=1 to number of rows)
do
mean[i]<-row[i]
done
return mean*
var data = System.IO.File.ReadAllText("Data.txt");
var arrays = new List<float[]>();
var lines = data.Split(new[] {'\r', '\n'}, StringSplitOptions.RemoveEmptyEntries);
foreach (var line in lines)
{
var lineArray = new List<float>();
foreach (var s in line.Split(new[] {','}, StringSplitOptions.RemoveEmptyEntries))
{
lineArray.Add(Convert.ToSingle(s));
}
arrays.Add(lineArray.ToArray());
}
var numberOfRows = lines.Count();
var numberOfValues = arrays.Sum(s => s.Length);
Found an efficient way to do this. Thanks for your input everybody!
private void ReadFile()
{
var lines = File.ReadLines("Data.csv");
var numbers = new List<List<double>>();
var separators = new[] { ',', ' ' };
/*System.Threading.Tasks.*/
Parallel.ForEach(lines, line =>
{
var list = new List<double>();
foreach (var s in line.Split(separators, StringSplitOptions.RemoveEmptyEntries))
{
double i;
if (double.TryParse(s, out i))
{
list.Add(i);
}
}
lock (numbers)
{
numbers.Add(list);
}
});
var rowTotal = new double[numbers.Count];
var rowMean = new double[numbers.Count];
var totalInRow = new int[numbers.Count()];
for (var row = 0; row < numbers.Count; row++)
{
var values = numbers[row].ToArray();
rowTotal[row] = values.Sum();
rowMean[row] = rowTotal[row] / values.Length;
totalInRow[row] += values.Length;
}
