sl3中的DataGrid中的数据导出到Excel中

把DataGrid中的数据导出到Excel

本例子只支持office2007以上版本

Page.xaml界面设计，Page.xaml代码如下:

    </Grid>
</UserControl>

首先建立一个简单的类 :

  public class Book
    {
        public string ID { get; set; }
        public string Name { get; set; }
        public double Price { get; set; }
    }

LayoutRoot_Loaded事件代码如下:

private void LayoutRoot_Loaded(object sender, RoutedEventArgs e)
        {
            List<Book> list = new List<Book>();
            for (int i = 0; i < 4; i++)
            {
                Book book = new Book();
                book.ID = i.ToString();
                book.Name = i.ToString() + "Silverlight开发  kafa";
                book.Price = 123456;
                list.Add(book);
            }
            DataGridTemplateColumn textColumnMax = new DataGridTemplateColumn();
            //textColumnMax.HeaderStyle = (Style)Application.Current.Resources["PacsDataGridColumnHeaderStyle"];
            //textColumnMax.CellStyle = (Style)Application.Current.Resources["PacsDataGridCellStyle"];
            //TextBlock tx = new TextBlock();
            //Binding bind = new Binding("Price");
            //bind.Converter = new DoubleConverter();
            //tx.SetBinding(TextBlock.TextProperty, bind);
            textColumnMax.Header = "最大值";
            //textColumnMax.CellTemplate = PACSSLAPP.AppCode.BuildDataTemplate.BuildDataTemple("MaxTech", 1);
            //PACSSLAPP.View.CommonControls.DoubleConverter conver = (PACSSLAPP.View.CommonControls.DoubleConverter)Application.Current.Resources["DoubleConverter"];
            textColumnMax.CellTemplate = BuildDataTemplate.BuildDataDoubleTemple("Price", 1);
            this.dg.Columns.Add(textColumnMax);
            this.dg.ItemsSource = list;

导出代码如下:

  private void btnExport_Click(object sender, RoutedEventArgs e)
        {
            //var context = dds.DomainContext as SuperEmployeeDomainContext;
            var context = dg.ItemsSource as List<Book>;
            var s = Application.GetResourceStream(new Uri("excelTemplate.txt", UriKind.Relative));
            var dialog = new SaveFileDialog();

            dialog.DefaultExt = "*.xml";
            dialog.Filter = "Excel Xml (*.xml)|*.xml|All files (*.*)|*.*";

            if (dialog.ShowDialog() == false) return;

            using (var sw = new StreamWriter(dialog.OpenFile()))
            {
                var sr = new StreamReader(s.Stream);
                while (!sr.EndOfStream)
                {
                    var line = sr.ReadLine();
                    if (line == "***") break;
                    sw.WriteLine(line);
                }
                sw.WriteLine("<Row>");
                sw.WriteLine("<Cell ss:StyleID=\"s76\"><Data ss:Type=\"String\">{0}</Data></Cell>", "");
                sw.WriteLine("<Cell><Data ss:Type=\"String\">{0}</Data></Cell>", "出版社");
                //sw.WriteLine("<Cell><Data ss:Type=\"String\">{0}</Data></Cell>", "作者");
                //sw.WriteLine("<Cell><Data ss:Type=\"Number\">{0}</Data></Cell>", "出版日期");
                sw.WriteLine("</Row>");
                foreach (var emp in context)
                {
                    sw.WriteLine("<Row>");
                    sw.WriteLine("<Cell><Data ss:Type=\"String\">{0}</Data></Cell>", emp.ID);
                    sw.WriteLine("<Cell><Data ss:Type=\"String\">{0}</Data></Cell>", emp.Name);
                    //sw.WriteLine("<Cell><Data ss:Type=\"String\">{0}</Data></Cell>", emp.Publishers);
                    //sw.WriteLine("<Cell><Data ss:Type=\"Number\">{0}</Data></Cell>", emp.Issues);
                    sw.WriteLine("</Row>");
                }
                while (!sr.EndOfStream)
                {
                    sw.WriteLine(sr.ReadLine());
                }
            }
