Two problems:
1) In C# an array of doubles is declared as double[] not []double
2) A Dictionary does not have an "add" property. It does have an Add method though:

Try:

C#

Dictionary<double[] , string> x = new Dictionary<double[] , string>();
Dictionary<double[] , string> y = new Dictionary<double[] , string>();
x.Add(File.ReadAllLines(@"E:\TestFile.txt").Aggregate("", (current, newLine) => current + " " + newLine).Split(' ').Where(s => !string.IsNullOrWhiteSpace(s)).Select(s => double.Parse(s)).ToArray(),"x array");
y.Add(File.ReadAllLines(@"E:\TestFile2.txt").Aggregate("", (current, newLine) => current + " " + newLine).Split(' ').Where(s => !string.IsNullOrWhiteSpace(s)).Select(s => double.Parse(s)).ToArray(),"y array");

But I have no idea if it will work...but it should compile!

double[] x = File.ReadAllLines(@"E:\TestFile.txt").Aggregate("", (current, newLine) => current + " " + newLine).Split(' ').Where(s => !string.IsNullOrWhiteSpace(s)).Select(s => double.Parse(s)).ToArray();
double[] y = File.ReadAllLines(@"E:\TestFile2.txt").Aggregate("", (current, newLine) => current + " " + newLine).Split(' ').Where(s => !string.IsNullOrWhiteSpace(s)).Select(s => double.Parse(s)).ToArray();
SimpleDTW dtw = new SimpleDTW(x, y);
dtw.computeDTW();
// double value = dtw.getSum();
double result = new SimpleDTW(x, y).computeFForward();
Console.WriteLine(result);
Console.ReadLine();

If "SomeDATAFile.txt" containing newline separated valid entries that can be parsed into Type double exists on your Desktop, this will work:

C#

private string path = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);

Dictionary<double[] , string> x = new Dictionary<double[] , string>();

double[] xAry = File.ReadAllText(path + @"\SomeDATAFile.txt")
    .Split(new string[] {Environment.NewLine}, StringSplitOptions.RemoveEmptyEntries)
    .Select(s => double.Parse(s)).ToArray();

x.Add(xAry,"x array");

I'd like to suggest that you can get better responses to questions like this (asked on StackOverFlow as well as here) if you:

1. give links to the source code you are using: for the DTW Class: [^]

2. On CodeProject, use the editor to format your code like you did on StackOverFlow.

3. clearly describe all error messages.

4. respond to questions asked you directly: do not repost code.

As you may know, Visual Studio Express is free; I think your productivity will improve if you can compile off-line.
