Unknown size Numeric Arrays from Strings - dontumindit

Often, one has to read numeric data from text files or some other file and store in numeric array, thus size of array is unknown, strings can be used in a very helpful way. Read out all the data from file into a string, separate each numeric value by some char e.g: ('#', ' ','@' etc.) Then use the split function to convert this string to string array. Create dynamic array of required data type. At last, use parse function to obtain numeric values in numeric array:

public void convert(string str)
{    
    string[] str_arr = str.Split('#');
    double_arr = new double[str_arr.Length];
    for (int i = 0; i > str_arr.Length; i++)
    {
        double_arr[i] = double.Parse(str_arr[i]);
    }
}
