asp.net - Using FileWriter in vb.net

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.

您必须刷新流以将其写入缓冲区，您可以调用writer.Flush或writer.Close使用using-statement 什么是使用一次性对象时的最佳实践：

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

之所以有效，是因为 aStreamWriter在处置之前就隐含地关闭了。
