我如何在VB.NET中编写下面的算法？

Procedure logfile()
{
    if "C:textfile.txt"=exist then
        open the textfile;
    else
        create the textfile;
    end if  
    go to the end of the textfile;
    write new line in the textfile;
    save;
    close;
}

Dim FILE_NAME As String = "C:textfile.txt"
Dim i As Integer
Dim aryText(4) As String

aryText(0) = "Mary WriteLine"
aryText(1) = "Had"
aryText(2) = "Another"
aryText(3) = "Little"
aryText(4) = "One"

Dim objWriter As New System.IO.StreamWriter(FILE_NAME,True)

For i = 0 To 4
    objWriter.WriteLine(aryText(i))
Next

objWriter.Close()
MsgBox("Text Appended to the File")

如果在System.IO.StreamWriter的构造函数中将第二个参数设置为True,则它将附加到文件(如果已存在),或者如果不存在则创建新文件.
