ToExcel() 知道文件名和保存位置的方法?

private void btnSave_Click(object sender, EventArgs e)
{
    //Creating Save File Dialog
    SaveFileDialog save = new SaveFileDialog();
    //Showing the dialog
    save.ShowDialog();
    //Setting default directory
    save.InitialDirectory = @"C:\";
    save.RestoreDirectory = true;
    //Setting title
    save.Title = "Select save location and input file name";
    //filtering to only show .xml files in the directory
    save.DefaultExt = "xml";
    //Write Data To Excel
    ToExcel();
}

private void ToExcel()
{
    var file = new FileInfo(Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory), "Test_" + DateTime.Now.ToString("M-dd-yyyy-HH.mm.ss") + ".xlsx"));

    using (var package = new ExcelPackage(file))
    {
        ExcelWorksheet ws = package.Workbook.Worksheets.Add("Test");
        ws.Cells[1, 1].Value = "One";
        ws.Cells["A1:C1"].Style.Font.Bold = true;
        package.Save();
        MessageBox.Show("Saved!");
    }
}

首先 ShowDialog 应该是您配置后通话的最后一行

然后使用FileName属性访问选定的文件名

最后把它传给任何你需要传给ie的人

private void btnSave_Click(object sender, EventArgs e)
{
    SaveFileDialog save = new SaveFileDialog();
    save.InitialDirectory = @"C:\";
    save.RestoreDirectory = true;
    save.Title = "Select save location file name";
    save.DefaultExt = "xml"; // surely should be xlsx??

    //Showing the dialog
    if(save.ShowDialog() == DialogResult.OK)
    {
        ToExcel(save.FileName);
    }
}
private void ToExcel(string saveFile){...}

此外,如果您想获取文件信息的方向,请检查 FileInfo.Directory
