// This might be wrong, I am writing this quick before heading out.


// Something like this
using System.IO;


StreamWriter file = new StreamWriter("out.txt");

string [] strings = {"red", "blue"};

foreach(String s in strings) {
   file.WriteLine(s);
}

file.Close() is missing at the end of code.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

hi! try this...

        private void button1_Click(object sender, EventArgs e)
        {
            string[] strArray = new string[] {"val1","val2","val3"};
            string filePath = Application.StartupPath + @"\Output.txt";

            using (System.IO.StreamWriter sw = new System.IO.StreamWriter(filePath))
            {
                foreach (string value in strArray)
                {
                    sw.WriteLine(value);
                }
            }
        }

You can change the file path if you want.

Hi cotj73

Try with attached code.
You can check if the file is existing and open it FileMode.Append mode.

string[] arr = { "text1", "text2" };
 
FileStream f = new FileStream("d://output.txt", FileMode.);
StreamWriter s = new StreamWriter(f);
 
foreach (string temp in arr)
{
    s.WriteLine(temp);
}
 
s.Close();
f.Close();
    

Open in new window

Hi

I just missed the mode in above answer.
Dont forget to close both the streams.
string[] arr = { "text1", "text2" };
 
FileStream f = new FileStream("d://output.txt", FileMode.Create);
StreamWriter s = new StreamWriter(f);
 
foreach (string temp in arr)
{
    s.WriteLine(temp);
}
 
s.Close();
f.Close();

Open in new window

I think we're all on the same path here,but if that gives you any trouble here is another (lazy) way to go. I dunno how you're trying to layout the text but this should give ya the idea:

        string[] myArray = new string[]{"One,Two","Buckle,My,Shoe"};

        StreamWriter sw = File.CreateText(Server.MapPath("~/files/") + "newFile.txt");
        foreach (string str in myArray)
        {
            string split = ",";
            char[] c = split.ToCharArray();
            string[] myArray2 = str.Split(c);
            foreach (string str2 in myArray2)
            {
                sw.WriteLine(str2);
            }
        }
        sw.Close();

I think it goes without saying that for all these solutions you need to get the namespace:

using system.io;
