选择文件选择文件夹

大家好，又见面了，我是你们的朋友全栈君。

namespace Microsoft.Win32

选择文件：

if (string.IsNullOrEmpty(folderInitialDirectory)) { folderInitialDirectory = FileAndFolderOperation.Instance.GetUserDocumentFolder(); }

SaveFileDialog saveFileDialog = new SaveFileDialog();

saveFileDialog.Title = Resources.ChooseExportFilePathWndTitle; saveFileDialog.InitialDirectory = folderInitialDirectory; saveFileDialog.Filter = Resources.ChooseExportFilePathWndFilter; saveFileDialog.FilterIndex = 1; saveFileDialog.RestoreDirectory = true; if (saveFileDialog.ShowDialog() == true) {

FilesPath = saveFileDialog.FileName; folderInitialDirectory = System.IO.Path.GetDirectoryName(FilesPath); }

选择文件夹：

Microsoft.WindowsAPICodePack.Dialogs

CommonOpenFileDialog dialog = new CommonOpenFileDialog(); dialog.IsFolderPicker = true; // 这里一定要设置true，不然就是选择文件 if (string.IsNullOrEmpty(folderInitialDirectory)) { folderInitialDirectory = FileAndFolderOperation.Instance.GetUserDocumentFolder(); } dialog.InitialDirectory = folderInitialDirectory; if (dialog.ShowDialog() == CommonFileDialogResult.Ok) { ToFolderPath = dialog.FileName; ImportExtentions.Instance.SetImpToFolderName(ToFolderPath); folderInitialDirectory =ToFolderPath; var zippath = ImportExtentions.Instance.ImpFromFolderName; var strZipPath = System.IO.Path.GetDirectoryName(zippath); string strRoot = System.IO.Path.GetPathRoot(strZipPath); var zipFreeSpace = FileAndFolderOperation.Instance.GetHardDiskFreeSpace(strRoot);

string strRoot1 = “”; var strPath = System.IO.Path.GetDirectoryName(ToFolderPath); if(!string.IsNullOrWhiteSpace(strPath)) strRoot1 = System.IO.Path.GetPathRoot(strPath); else strRoot1 = System.IO.Path.GetPathRoot(ToFolderPath);

var lfreeSpace = FileAndFolderOperation.Instance.GetHardDiskFreeSpace(strRoot1);

if (zipFreeSpace > lfreeSpace) { SetSizeErrorInfo(); return; }}
