winform中 saveFileDialog 和openFileDialog 保存文件的用法

saveFileDialog  用法 

#region saveFileDialog的实现
            {
                //string localFilePath, fileNameExt, newFileName, FilePath;  
                string localFilePath = String.Empty;
                SaveFileDialog saveFileDialog1 = new SaveFileDialog();

                //设置文件类型  
                saveFileDialog1.Filter = " xls files(*.xls)|*.txt|All files(*.*)|*.*";
                //设置文件名称：
                saveFileDialog1.FileName = DateTime.Now.ToString("yyyyMMdd") + "-" + "资产信息报表.xls";

                //设置默认文件类型显示顺序  
                saveFileDialog1.FilterIndex = 2;

                //保存对话框是否记忆上次打开的目录  
                saveFileDialog1.RestoreDirectory = true;

                //点了保存按钮进入  
                if (saveFileDialog1.ShowDialog() == DialogResult.OK)
                {
                    //获得文件路径  
                    localFilePath = saveFileDialog1.FileName.ToString();
                    //string filname = this.openFileDialog2.FileName;
                    //获取文件名，不带路径  
                    //fileNameExt = localFilePath.Substring(localFilePath.LastIndexOf("\\") + 1);  

                    //获取文件路径，不带文件名  
                    //FilePath = localFilePath.Substring(0, localFilePath.LastIndexOf("\\"));  

                    //给文件名前加上时间  
                    //newFileName = DateTime.Now.ToString("yyyyMMdd") + fileNameExt;  

                    //在文件名里加字符  
                    //saveFileDialog1.FileName.Insert(1,"dameng");  

                    //System.IO.FileStream fs = (System.IO.FileStream)saveFileDialog1.OpenFile();//输出文件  

                    //fs输出带文字或图片的文件，就看需求了  
                }
               
            }

openFileDialog 用法：

 #region openFileDialog保存的用法
            {
                //string filname = this.openFileDialog2.FileName;
                //// 设置根在桌面SpecialFolder
                //fbdSelectFolder.RootFolder = Environment.SpecialFolder.Desktop;

                //// 设置当前选择的路径
                //fbdSelectFolder.SelectedPath = "C:\\";

                //// 允许在对话框中包括一个新建目录的按钮
                //fbdSelectFolder.ShowNewFolderButton = true;

                //// 设置对话框的说明信息
                //fbdSelectFolder.Description = "请选择输出目录";

                //string selectPath = "资产信息报表";

                //if (fbdSelectFolder.ShowDialog() == DialogResult.OK)
                //{
                //    // 在此添加代码
                //    selectPath = fbdSelectFolder.SelectedPath;
                //}
            }
            #endregion
