    SaveFileDialog saveFile = new SaveFileDialog();
                saveFile.Title = "save file";
                saveFile.AddExtension = true;
                saveFile.Filter = "file(*.cfg)|*.cfg|all file(*.*)|*.*";
                saveFile.InitialDirectory = runPath;
                saveFile.FileName = "default.cfg";
                if (saveFile.ShowDialog() == DialogResult.OK)
                {
                    SaveDeviceDatas(saveFile.FileName);
                    MessageBox.Show("保存成功！" + saveFile.FileName, "Information", MessageBoxButtons.OK, MessageBoxIcon.Information);
                }

2.加载文件对话框

            openFileDialog.RestoreDirectory = true;
            openFileDialog.FilterIndex = 1;
            openFileDialog.InitialDirectory = runPath;
            openFileDialog.FileName = "default.cfg";
            if (openFileDialog.ShowDialog() == DialogResult.OK)
            {               
                LoadDeviceDataFromXML(openFileDialog.FileName);

            }
