写入文件,文件正被另一个进程使用 [英] Writing to file, file being used by another process
本文介绍了写入文件,文件正被另一个进程使用的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
好的,所以我不明白为什么我不能写入文件.它说它正在被另一个进程使用.这是错误(IOException 未处理):
Alright, so I can't figure out why I can't write to a file. It says it's being used by another process. Here's the error (IOException was unhandled):
The process cannot access the file 'C:\Temp\TempFile.cfg' because it is being used by another process.
这是我用来写入文件的当前代码:
Here's the current code I'm using to write to the file:
Dim myConfig
Dim saveFileDialog1 As New SaveFileDialog()
saveFileDialog1.Filter = "Configuration Files (*.cfg)|*.cfg"
saveFileDialog1.FilterIndex = 2
saveFileDialog1.RestoreDirectory = True
If saveFileDialog1.ShowDialog() = DialogResult.OK Then
myConfig = saveFileDialog1.OpenFile()
If (myConfig IsNot Nothing) Then
System.IO.File.WriteAllText(saveFileDialog1.FileName, TextBox1_Output_Module.Text & vbCrLf & TextBox2_Output_Module.Text & vbCrLf & TextBox3_Output_Module.Text)
myConfig.Close()
End If
End If
我不确定我错过了什么,因为我以为我昨天测试了它并且它有效.
I'm not sure what I am missing as I thought I tested this yesterday and it worked.
推荐答案
好吧,这就是我最终做的,似乎工作得很好.我取出了 if 条件并保留了其他所有内容.我以后可以随时为取消编码.
Well here's what I ended up doing, seems to be working just fine as is. I took out the if condition and left everything else as is. I can always code for the cancel later on.
Dim myConfig
Dim saveFileDialog1 As New SaveFileDialog()
saveFileDialog1.Filter = "Configuration Files (*.cfg)|*.cfg"
saveFileDialog1.FilterIndex = 2
saveFileDialog1.RestoreDirectory = True
System.IO.File.WriteAllText(saveFileDialog1.FileName, TextBox1_Output_Module.Text & vbCrLf & TextBox2_Output_Module.Text & vbCrLf & TextBox3_Output_Module.Text)
这是确定/取消按钮的代码.
This codes for the ok/cancel button.
If saveFileDialog1.ShowDialog() = Windows.Forms.DialogResult.OK Then
System.IO.File.WriteAllText(saveFileDialog1.FileName, TextBox1_Output_Module.Text & vbCrLf & TextBox2_Output_Module.Text & vbCrLf & TextBox3_Output_Module.Text)
End If
