What I have tried:

private void btnOpenFiles_Click(object sender, RoutedEventArgs e)
{
openFileDialog.Multiselect = true;
openFileDialog.Filter = "Text files (*.txt)|*.txt|All files (*.*)|*.*";
openFileDialog.InitialDirectory = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
if (openFileDialog.ShowDialog() == true)
{
foreach (string filename in openFileDialog.FileNames)
{
lbFiles.Items.Add(System.IO.Path.GetFileName(filename));
}
}
}
private void lbFiles_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
object item = lbFiles.SelectedItem;
if (item == null)
{
txtEditor.Text = "No Item Selected";
}
else
{
txtEditor.Text = File.ReadAllText(openFileDialog.FileName);
}
}
推荐答案
txtEditor.Text = File.ReadAllText(openFileDialog.FileName);
您正在打开 openFileDialog 中的文件，而不是<$ c中所选项目中的文件$ c> ListBox 。
[edit]
代码应该是这样的：
You are opening the file from the openFileDialog instead of the one in the selected item of the ListBox.
[edit]
The code should be something like:
private void lbFiles_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
object item = lbFiles.SelectedItem;
if (item == null)
{
txtEditor.Text = "No Item Selected";
}
else
{
txtEditor.Text = File.ReadAllText(item.ToString());
}
}
