Write text to file using stream writer

Question

I am having some trouble writing a string MentionsInText to a file using the Systems.IO.StreamWriter according to the file it is edited when the code is run however, no text is present in the file. I am not sure why this is not working. My code is as follows;

 var MIS = string.Join(" ", MentionsList.ToArray());
 string Mentionsintext = MIS.ToString();

 StreamWriter MentionFile = new StreamWriter(@"C:\Users\User\Documents\Mentions.txt");

 MentionFile.WriteLine(Mentionsintext + Environment.NewLine);

Am I doing something wrong when using StreamWriter?

Answer 1

You should dispose of the StreamWriter after writing to it.

eg:

 var MIS = string.Join(" ", MentionsList.ToArray());
 string Mentionsintext = MIS.ToString();

 using (StreamWriter MentionFile = new StreamWriter(@"C:\Users\User\Documents\Mentions.txt")) {

      MentionFile.WriteLine(Mentionsintext + Environment.NewLine);

 }
