[英]How to write textbox values to .txt file with vb.net
I have a simple form with two textboxes, I want Textbox1
to write to a file named C:\\VALUE1.txt
and Textbox2
to write its value to a file named C:\\VALUE2.txt
我有一个带有两个文本框的简单表单,我希望Textbox1
写入名为C:\\VALUE1.txt
的文件,并且Textbox2
将其值写入名为C:\\VALUE2.txt
的文件
Any text that is already in the text file MUST be over written. 文本文件中已经存在的任何文本都必须被覆盖。
It's worth being familiar with both methods: 值得熟悉这两种方法:
1) In VB.Net you have the quick and easy My.Computer.FileSystem.WriteAllText option: 1)在VB.Net中,您可以轻松快捷地使用My.Computer.FileSystem.WriteAllText选项:
My.Computer.FileSystem.WriteAllText("c:\value1.txt", TextBox1.Text, False)
2) Or else you can go the "long" way round and use the StreamWriter object. 2)否则,您可以走很长一段路,然后使用StreamWriter对象。 Create one as follows - set false in the constructor tells it you don't want to append: 如下创建一个-在构造函数中设置false告诉您您不想追加:
Dim objWriter As New System.IO.StreamWriter("c:\value1.txt", False)
then write text to the file as follows: 然后将文本写入文件,如下所示:
objWriter.WriteLine(Textbox1.Text)
objWriter.Close()
Dim FILE_NAME As String = "C:\VALUE2.txt"
If System.IO.File.Exists(FILE_NAME) = True Then
Dim objWriter As New System.IO.StreamWriter(FILE_NAME)
objWriter.Write(TextBox2.Text)
objWriter.Close()
MsgBox("Text written to file")
Else
MsgBox("File Does Not Exist")
End If
看一下System.IO
和System.Text
命名空间,尤其是StreamWriter
对象。
