實現能夠選擇文件夾

  大家都用過C#裏的文件打開/保存對話框吧?方便明快且易上手.但是可惜的是,C#居然沒提供同樣的文件夾選擇框,很多人通過P/I invoke使用了系統的一些函數來實現對話框,那是相當地不方便啊~~其實,C#的FolderNameEditor類在某種程度上就實現了文件夾選擇框的功能,只不過沒有完全包裝出來.呵呵,今天就給讀者放出一個使用C#自己的類實現的對話框,使用起來就跟OpenFileDialog一樣簡單易用.
 
//給文件夾選擇框類起名叫OpenFolderDialog,類設計如下: public class OpenFolderDialog : FolderNameEditor, IDisposable { FolderNameEditor.FolderBrowser fDialog = new FolderNameEditor.FolderBrowser(); public OpenFolderDialog() { } public DialogResult ShowDialog() { return ShowDialog("Select a folder:"); } public DialogResult ShowDialog(string description) { fDialog.Description = description; return fDialog.ShowDialog(); } public string Path { get { return fDialog.DirectoryPath; } } public void Dispose() { fDialog.Dispose(); } } //使用實例: private void selectFolderButton_Click(object sender, EventArgs e) { using (OpenFolderDialog openFolderDlg = new OpenFolderDialog()) { if (openFolderDlg.ShowDialog() == DialogResult.OK) { this.outFolderTextBox.Text = openFolderDlg.Path; } } } //下面是對照的OpenFolderDialog使用實例,對照一下,是不是很相似? private void selectFileButton_Click(object sender, EventArgs e) { using (OpenFileDialog openDlg = new OpenFileDialog()) { openDlg.Filter = @"All text Files(*.txt)|*.txt"; openDlg.Multiselect = false; openDlg.RestoreDirectory = true; openDlg.FilterIndex = 1; if (openDlg.ShowDialog() == DialogResult.OK) { this.filePathTextBox.Text = openDlg.FileName; } } }
