C#選擇文件（OpenFileDialog）、選擇文件夾（FolderBrowserDialog）

1  選擇文件（OpenFileDialog）

            OpenFileDialog dialog = new OpenFileDialog();
            //dialog.Multiselect = true;//該值確定是否可以選擇多個文件
           // dialog.Title = "請選擇文件";
            //dialog.Filter = "所有文件(*.*)|*.*";
            //dialog.InitialDirectory = @"E:\";
            if (dialog.ShowDialog() == System.Windows.Forms.DialogResult.OK)
            {
                string fullFileName = dialog.FileName;// @"e:\日記.doc";
                //var FileName =System.IO.Path.GetFileName(fullFileName); //文件名  “日記.doc”
                //string extension = System.IO.Path.GetExtension(fullFileName);//擴展名 “.doc”
                //string fileNameWithoutExtension = System.IO.Path.GetFileNameWithoutExtension(fullFileName);// 沒有擴展名的文件名 “日記”

            }

2  選擇文件夾(System.Windows.Forms.FolderBrowserDialog)

            System.Windows.Forms.FolderBrowserDialog dialog = new System.Windows.Forms.FolderBrowserDialog();
            dialog.Description = "請選擇Txt所在文件夾";
            if (dialog.ShowDialog() == System.Windows.Forms.DialogResult.OK)
            {               string path = dialog.SelectedPath; // "e:/go"
            }
