我有一個正在更新日誌信息的富文本框。有一個按鈕可以將日誌輸出保存到文件中。當我使用下面的代碼嘗試將輸出保存到文件時,我收到「進程無法訪問該文件,因爲它正在被另一個進程使用」異常。我不知道爲什麼我收到這個例外。它發生在我在對話框中創建的新文件中。它發生在我嘗試保存信息的任何文件上。C#進程無法訪問文件,因爲它正在被另一個進程使用(文件對話框)
private void saveLog_Click(object sender, EventArgs e)
{
OnFileDialogOpen(this, new EventArgs());
// Displays a SaveFileDialog so the user can save the Image
// assigned to Button2.
SaveFileDialog saveFileDialog1 = new SaveFileDialog();
saveFileDialog1.Filter = "Text File|*.txt|Log File|*.log";
saveFileDialog1.Title = "Save Log File";
saveFileDialog1.ShowDialog();
// If the file name is not an empty string open it for saving.
if (saveFileDialog1.FileName != "")
{
// Saves the Image via a FileStream created by the OpenFile method.
System.IO.FileStream fs =
(System.IO.FileStream)saveFileDialog1.OpenFile();
// Saves the Image in the appropriate ImageFormat based upon the
// File type selected in the dialog box.
// NOTE that the FilterIndex property is one-based.
switch (saveFileDialog1.FilterIndex)
{
case 1:
try
{
this.logWindow.SaveFile(saveFileDialog1.FileName, RichTextBoxStreamType.PlainText);
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString());
}
break;
case 2:
try
{
this.logWindow.SaveFile(saveFileDialog1.FileName, RichTextBoxStreamType.PlainText);
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString());
}
break;
}
fs.Close();
OnFileDialogClose(this, new EventArgs());
}
}
謝謝,是它 –
