This is the second time I answered other's question. However my answer is not accepted as answer. It makes me frustrated and do not want to contribute to this forum any more.

another optional way for writing to Text which is better if you also want to know the current lines information in the file List textList = new List (); textList.AddRange(File.ReadAllLines(filepath); // Insert your new text here textList.Insert(0 newTextLine); // Write to file File.WriteAllLines(filepath textList.ToArray());

you can use this code for this: private void file_append() { string path=D:\Temp\My Documents\; // Parent Directory string name=TextBox1.Text; string ext=.txt; string fname=path+name+ext; FileInfo file1=new FileInfo(fname); StreamWriter sw=File.AppendText(file1) sw.WriteLine(This is a demo for appending text content to a file); // Writing a string directly to the file sw.WriteLine(TextBox2.Text); // Writing content read from the textbox in the form sw.Close(); }
