passing string value to double array c#

Question

I currently have a application that reads back the contents of the text file in a string. I want to put all those values in a double array I have created but can't seem to get it to work here is my code :

using (StreamReader sr = new StreamReader("test.txt"))
{
    String line =  sr.ReadToEnd();
    x = doubles;
    Console.WriteLine(x);
}

Everytime I run it I get the error "file could not be read: input string was not in a correct format" Does anyone have any idea whats wrong?

file could not be read: input string was not in a correct format is that the literal text of the exception? I'm pretty sure it's not. We can't really help unless we know the literal exception text. — Mike Perrenoud

bool bSuccess;
double value;
bSuccess = double.TryParse("3.14", out value);

This answers his implied question, but if you re-read the OP's question, the problem is on reading the file.

if you reread the title, you will find it different. so let's wait OP to clarify.

double[] x = new double [3501]; double[] doubles = Array.ConvertAll(line.Split('\n'), new Converter<String, double>(Double.Parse));

Make sure that your file path is delcared for the StreamReader, simply stating "test.txt" with no apparent location does not access the file you are attempting to read from.
