在vb.net中使用FileWriter

Question

I am trying to write some text at the end of the file.

Here is my code

Dim Writer As System.IO.StreamWriter = IO.File.AppendText("D:\Vishal.txt")
Writer.WriteLine("I am Vishal")

But I am not getting anything in the above mentioned file. Also there are no errors in the program.

Answer 1

You have to flush the stream to write it's buffer, you could call writer.Flush , writer.Close or use the using -statement what is best practise anyway when using disposable objects:

Using Writer As System.IO.StreamWriter = IO.File.AppendText("D:\Vishal.txt")
    Writer.WriteLine("I am Vishal")
End Using

That works because a StreamWriter gets closed implicitely before it's disposed.
