推荐答案
我同意Manas ..我不认为有任何方法可以过滤驱动器：但你可以按照所示的方式进行操作：
OpenFileDialog ofd = new OpenFileDialog（）;
ofd.CustomPlaces.Clear（）;
foreach（System.IO.DriveInfo.GetDrives（）中的var项目）
{
if（item.DriveType == DriveType.Removable）
ofd.CustomPlaces.Add（item.RootDirectory.ToString（））;
}
if（ofd.ShowDialog（）== DialogResult.OK）
{
FileInfo f = new FileInfo （ofd.FileName）;
string s = f.Directory.Root.ToString（）;
DriveInfo df = new DriveInfo;
if（df.DriveType == DriveType.Removable）
{
//带文件的STUFF
}
}
i am agree with Manas .. i dont think there is any way to filter with drives: but u can to following stuff as shown:
OpenFileDialog ofd = new OpenFileDialog();
ofd.CustomPlaces.Clear();
foreach (var item in System.IO.DriveInfo.GetDrives())
{
if (item.DriveType == DriveType.Removable)
ofd.CustomPlaces.Add(item.RootDirectory.ToString());
}
if (ofd.ShowDialog() == DialogResult.OK)
{
FileInfo f = new FileInfo(ofd.FileName);
string s = f.Directory.Root.ToString();
DriveInfo df = new DriveInfo(s);
if (df.DriveType == DriveType.Removable)
{
//DO STUFF WITH FILE
}
}
我不认为有可能实现你想用OpenFileDialog做的事情。
您可以编写自己的自定义对话框，也可以在进行选择后进行验证。
I don't think that it is possible to to achieve what you are trying to do with OpenFileDialog.
You can either write your own custom dialog or do validation after you have made the selection.
使用substring函数获取路径的前两个字符，
如果路径以\\，它应该是一个以网络驱动器名称开头的路径。
否则，您可以切断前3个字符并添加驱动器名称。
Use substring function to get the first two characters of the path,
if the path start with \\, it should be a path start with network drive name.
Else, you can cut off the first 3 characters and add the drive name.
