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
