WPF选择文件夹及文件操作

WPF本身并没有相关的类，需要引用winform的命名空间

System.Windows.Forms

获取文件夹路径

System.Windows.Forms.FolderBrowserDialog m_Dialog = new System.Windows.Forms.FolderBrowserDialog();
            System.Windows.Forms.DialogResult result = m_Dialog.ShowDialog();

            if (result == System.Windows.Forms.DialogResult.Cancel)
            {
                return;
            }
            string m_Dir = m_Dialog.SelectedPath.Trim();

获取指定文件

using Microsoft.Win32;

OpenFileDialog openFileDialog = new OpenFileDialog();
            openFileDialog.Title = "选择数据源文件";
            openFileDialog.Filter = "txt文件|*.txt|rar文件|*.rar|所有文件|*.*";
            openFileDialog.FileName = string.Empty;
            openFileDialog.FilterIndex = 1;
            openFileDialog.Multiselect = false;
            openFileDialog.RestoreDirectory = true;
            openFileDialog.DefaultExt = "txt";
            if (openFileDialog.ShowDialog() == false)
            {
                return;
            }
            string txtFile = openFileDialog.FileName;
