问题 I need a control like SaveFileDialog that lets me choose a directory instead of a file. It should also let me specify the directory by pasting text. SaveFileDialog does not allow this. I have tried FolderBrowserDialog , but it does not meet my requirements because it does not support pasting the directory path as text. Some of the directory I'm working with may be nested 10 levels or more, so being forced to navigate via point-and-click is not enough. Thanks in advance. 回答1:

问题 var dlg = new SaveFileDialog(); dlg.FileName = "graph"; dlg.DefaultExt = ".bmp"; dlg.Filter = "PNG|*.png|DOT|*.dot|Windows Bitmap Format|*.bmp|GIF|*.gif|JPEG|*.jpg|PDF|*.pdf|Scalable Vector Graphics|*.svg|Tag Image File Format|*.tiff"; The extension always defaults to .png . It seems the DefaultExt is ignored if there is a Filter ; then it just defaults to the first option in the list. Is there a way to force it to actually respect the default ext? 回答1: You should set FilterIndex property

问题 I have a webpage encoding a local file into Base64, and would like to give the user an option to save the result - now residing in a html element - without going back to the server. I could post the data to a back-end webpage, save as file, and offer a <a href= .. but I would much appreciate the option of fulfilling this on the client side. The file can easily be too big for a post.. Could I write som javascript code to initiate a save dialog, and push the file content back to the user if he

问题 I'm on Vista and I'm using Microsoft.Win32.OpenFileDialog class. When I call ShowDialog() I get the old XP-style dialog: How do I get the new Vista-style dialog with fallback to the old one on WindowsXP? A bit of rumble: I don't really understand why they didn't replace the dialog in vista, but kept both of them. Now legacy apps will never open new dialog, unless updated. 回答1: Yes, you'd have to upgrade to .NET 4.0 to get the new dialog. If you're stuck on 3.5 then you can use System.Windows

问题 I'd like the standard windows open and save file dialogs, however, the particular application I am using it for is a remote file system (basically, I'd love to somehow just provide a IFileSystem interface to SaveFileDialog and have it magically change the files it sees by me providing them). Does anyone know of a complete implementation of those dialogs that supports this functionality? Is there any way to do it with the standard C#/windows dialogs? If not, I will be implementing the dialog
