C#,Winform 文件的导入导出 File

1、导入

导入对话框：OpenFileDialog

private void sbtnsb_Click(object sender, EventArgs e)

        {

            try

            {

                OpenFileDialog ofd = new OpenFileDialog();

                ofd.Filter = "导入文件包(*.bak)|*.bak";//扩展名

                ofd.FileName = "导入的文件包名称";

                if (ofd.ShowDialog() == DialogResult.OK)

                {

                    string savePath = System.AppDomain.CurrentDomain.BaseDirectory + "data\\reportData\\";//要导出文件的路径

                    if (!File.Exists(savePath))

                    {

                        string saveName = ofd.FileName.Substring(ofd.FileName.LastIndexOf("\\") + 1, ((ofd.FileName.IndexOf(".bak") - 1) - ofd.FileName.LastIndexOf("\\")));

                        string dataPath = savePath + saveName + ".mdb";//文件地址

                        string dataName = saveName + ".mdb";//文件名

                        File.Copy(ofd.FileNames[0], dataPath, true);

            MessageBox.Show("导入成功！");

                    }

                }

            }

            catch (Exception ex)

            {

                MessageBox.Show("导入.bak文件错误信息：" + ex.Message);

            }

        }

2、导出

导出对话框：SaveFileDialog

private void sbtndc_Click(object sender, EventArgs e)

        {

            try

            {

                SaveFileDialog sfd = new SaveFileDialog();

                sfd.Filter = "导出文件包(*.baks)|*.baks";//扩展名

                sfd.FileName = "这是导出的文件包";//导出文件包文件名



                if (sfd.ShowDialog() == DialogResult.OK)

                {

                    string dataPath = System.AppDomain.CurrentDomain.BaseDirectory + "data\\skymxm.mdb";

                    if (File.Exists(dataPath))

                    {

                        File.Copy(dataPath, sfd.FileNames[0], true);

                        MessageBox.Show("导出成功!");

                    }

                }

            }

            catch (Exception ex)

            {

                MessageBox.Show("导出.bak文件错误信息：" + ex.Message);

            }

        }
