// 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.

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;
