如何使用 vb.net 将文本框值写入 .txt 文件
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 和 Textbox2 的文件将其值写入名为 C:\VALUE2.txt
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
必须覆盖文本文件中已有的任何文本.
Any text that is already in the text file MUST be over written.
这两种方法都值得熟悉:
It's worth being familiar with both methods:
1) 在 VB.Net 中，您有快速简便的 My.Computer.FileSystem.WriteAllText 选项:
1) In VB.Net you have the quick and easy My.Computer.FileSystem.WriteAllText option:
My.Computer.FileSystem.WriteAllText("c:\value1.txt", TextBox1.Text, False)
2) 否则，您可以走长"路并使用 StreamWriter 对象.如下创建一个 - 在构造函数中设置 false 告诉它你不想追加:
2) Or else you can go the "long" way round and use the StreamWriter object. Create one as follows - set false in the constructor tells it you don't want to append:
Dim objWriter As New System.IO.StreamWriter("c:\value1.txt", False)
然后将文本写入文件，如下所示:
then write text to the file as follows:
objWriter.WriteLine(Textbox1.Text)
objWriter.Close()
