我正在开发一个 WPF 应用程序。
请检查此图像：
当我单击 + 号按钮时，我想在下面的网格中显示附件路径。为此，我做了一些工作，我将在下面向您展示。

.CS 文件
private void attachmentTool_AddRowClick(object sender, RoutedEventArgs e)
{
Microsoft.Win32.OpenFileDialog dlg = new Microsoft.Win32.OpenFileDialog();
// Set filter for file extension and default file extension
//dlg.DefaultExt = ".txt";
//dlg.Filter = "Text documents (.txt)|*.txt";
// Display OpenFileDialog by calling ShowDialog method
Nullable<bool> result = dlg.ShowDialog();
// Get the selected file name and display in a TextBox
if (result == true)
{
try
{
// Open document
string filePath = dlg.FileName;
AttachmentInfo info = new AttachmentInfo();
info.LocalPath = filePath;
info.FileName = System.IO.Path.GetFileNameWithoutExtension(filePath);
info.FileExtension = System.IO.Path.GetExtension(filePath).Replace(".", "");
Stream strm = dlg.OpenFile();
byte[] data = new byte[strm.Length];
strm.Read(data, 0, data.Length);
info.AttachmentContent = data;
strm.Close();
strm.Dispose();
this.dxgAttachment.ItemsSource = info;
}
catch (Exception ex)
{
DXMessageBox.Show("Unable to attach file. " + ex.Message);
}
}
}
问题
如何在网格中显示附件路径？
附加单个或多个文件后，我还想将所有文件保存在数据库中。这个怎么做？
通过使用上面的代码，我无法在网格中显示附件列表。
