Reading file passing contents to array accessing contents

Question

Hi I want to read a file which has some data as its contents. I have managed to read the file but not explicit values. I want to store each data in an array (leaving out spaces or other characters #$?//) and access these contents and assign them later on in my program to some variables. Any ideas? I have a file with values 1 2 3 4 5 and so on. How can I read them store them and then access them ? It might be a no-brainer but i'm stuck. cheers

correction: tmpstr += tmp+ ; // 5 spaces in quotes tmpstr = tmpstr.Replace(   ); // replace 5 spaces with one space

Try this: StreamReader sr = new StreamReader(@G:\1.txt); string tmpstr =  tmp; while ((tmp = sr.ReadLine()) != null) { tmpstr += tmp+ ; } tmpstr = tmpstr.Replace(   ); s_vals = tmpstr.Split(' '); d_vals = new double[s_vals.Length]; for (int i = 0; i < s_vals.Length; i++) { if (s_vals[i] != ) { d_vals[i] = Convert.ToDouble(s_vals[i]); } }

Thanks for your reply unfortunately this did not work. My text file is like this: totalOfPoint: 300 1.0 2.0 3.0 4.0 5.0 6.0 7.0 8.0 9.0 and so on there are 5 spaces between number in a line. But 3.0 and 4.0 have no space bewteen them. i am using the Split(' ') function to separate a single split. If I change my file and have single splits everything works. But the problem is that the program that outputs the text file has 5 spaces between numbers. cheers

try to play with Trim() and Replace() functions. something like this: txtstr = txtstr.Replace(
 ); txtstr = txtstr.Replace( ); txtstr = txtstr.Replace(   ); //replace all two spaces to one space txtstr = txtstr.Trim(); or may be a better way try this: on read: tmpstr = reader.ReadLine(); tmpstr = tmpstr.Trim(); tmpstr = tmpstr.Replace(
 ); tmpstr = tmpstr.Replace( ); txtstr += tmpstr; If this will not work - give me an example of your input file.

Thanks for your reply I'm using this: StreamReader reader = new StreamReader(C:\mytext.txt); string text = string.Empty; while( reader.Peek() != -1 ) { text += reader.ReadLine(); } reader.Close(); string[] parts = text.Split(' '); for(int i = 0; i < (parts.Length - 1); i++) { Console.WriteLine( parts[i] + ; ); }} but i'm getting some funny results. Although i get the file contents they are not shown in correct order. Maybe the fact that between each number there are more than one spaces plays some role. I don't know. Should be getting output : 1 2 3 4 and so on but instead i get 1 2 3 4 5 6 that sound odd right? any ideas? cheers

try somethign like this: public string[] data; //inside a reading data function string tmpstr = sr.ReadLine(); //sr - StreamReader created for your data file data = tmpstr.Split(' '); // if your separator between values is space // now data array is your array of values in string format. You can use it and access it.
