StreamWriter in C#

I want to append to the end of a file.  I have done this:

                        string filename = outpath + @"\" + fname + ".txt";
                        if(File.Exists(filename))
                        {
                              fs = File.OpenWrite(filename);
                        }
                        else
                        {
                               fs = File.Create(filename);
                        }

                        StreamWriter sw;
                        sw =       new StreamWriter(fs);
                        
                              sw.WriteLine(ohlc);

This writes to the begining of the file.  Please advice how I can set the pointer to the end oif the file.  Thx

Hi

ho this if file exists then call the AppendText method

.....
if(File.Exists(filename))
{
      fs = File.AppendText(filename);                        
}
....

and the else condition remains same. you can however replace Create function with CreateText

you can directly create stream writer as

string filename = outpath + @"\" + fname + ".txt";
StreamWriter sw;
if(File.Exists(filename))
{
      sw = File.AppendText(filename);                        
}
else
{
      sw = File.CreateText(filename);
}
                          
sw.WriteLine(ohlc);
