What is the simplest way to write the contents of a StringBuilder to a text file in NET 1 1

Question

I have to use StringBuilder instead of a List of strings because of being stuck with  NET 1 1 for this project    I want to write a series of debug messages I ve written to a file to study at my leisure  as there is too much to see on the screen  the MessageBox doesn t have scrollbars   Some of the easy ways to write a file don t seem to be available in  NET 1 1  I also don t have access to Environment Newline to cleanly separate the lines I append  AppendLine is not available in this archaic version of StringBuilder  either    What is the easiest way in  NET 1 1  C   to write out the contents of the StringBuilder to a file  There is no  C  drive on the handheld device  so I reckon I will have to write it to   hereIAm txt  or something

If you need to write line by line from string builder

StringBuilder sb = new StringBuilder();
sb.AppendLine("New Line!");

using (var sw = new StreamWriter(@"C:\MyDir\MyNewTextFile.txt", true))
{
   sw.Write(sb.ToString());
}

If you need to write all text as single line from string builder

StringBuilder sb = new StringBuilder();
sb.Append("New Text line!");

using (var sw = new StreamWriter(@"C:\MyDir\MyNewTextFile.txt", true))
{
   sw.Write(sb.ToString());
}

I know this is an old post and that it wants an answer for  NET 1 1 but there s already a very good answer for that  I thought it would be good to have an answer for those people who land on this post that may have a more recent version of the  Net framework  such as myself when I went looking for an answer to the same question    In those cases there is an even simpler way to write the contents of a StringBuilder to a text file  It can be done with one line of code  It may not be the most efficient but that wasn t really the question now was it   System IO File WriteAllText   C  MyDir MyNewTextFile txt  sbMyStringBuilder ToString

StreamWriter is available for NET 1 1  and for the Compact framework  Just open the file and apply the ToString to your StringBuilder       StringBuilder sb   new StringBuilder        sb Append               StreamWriter sw   new StreamWriter    hereIAm txt   true       sw Write sb ToString         sw Close      Also  note that you say that you want to append debug messages to the file  like a log   In this case  the correct constructor for StreamWriter is the one that accepts an append boolean flag  If true then it tries to append to an existing file or create a new one if it doesn t exists

You still have access to StreamWriter   using  System IO StreamWriter file   new System IO StreamWriter    hereIam txt          file WriteLine sb ToString         sb  is the StringBuilder     From the MSDN documentation  Writing to a Text File  Visual C     For newer versions of the  NET Framework  Version 2 0  onwards   this can be achieved with one line using the File WriteAllText method   System IO File WriteAllText   C  TextFile txt   stringBuilder ToString

No need for a StringBuilder      string path     c  hereIAm txt   if   File Exists path             Create a file to write to      using  StreamWriter sw   File CreateText path                  sw WriteLine  Here            sw WriteLine  I            sw WriteLine  am                    But of course you can use the StringBuilder to create all lines and write them to the file at once   sw Write stringBuilder ToString       StreamWriter Write Method  String    NET Framework 1 1   Writing Text to a File   NET Framework 1 1
