I have data in this form:
double[][] rawData = new double[3][];
rawData[0] = new double[] { 65.0, 220.0 };
rawData[1] = new double[] { 73.0, 160.0 };
rawData[2] = new double[] { 59.0, 110.0 };
Now I want to import data from text file and use in place of this array data. I want double type jagged array for text file data too.
Data of each row in file is of form: 5.1,3.5,1.4,0.2
There are total 150 rows in text file. I want to read file line by line, split by comma and save each line in double type array as in case of rawData[]][]
.
Try using Linq , you have to
items
by commaDouble
Implementation
// let txt file being a CSV-like one
Double[][] data = File
.ReadLines(@"C:\MyFile.txt")
.Where(line => !String.IsNullOrEmpty(line.Trim())) // to remove empty lines if any
.Select(line => line.Split(','))
.Select(items => items
.Select(item => Double.Parse(item, CultureInfo.InvariantCulture))
.ToArray()) // inner array
.ToArray(); // outer array
