導出Silverlight網格到Excel工作表只寫1行

我有一個web silverlight應用程序，可以讓用戶從桌面上選擇一個excel文件，並添加3個excel列。這部分在桌面應用程序中正常工作。但我們需要這個作爲一個Web應用程序。現在Web應用程序只寫第一行。我已經有了一個'導出'功能，可以將網格上的內容製作成excel文件。導出Silverlight網格到Excel工作表只寫1行

你只能通過在工作表中的行循環：

for (int J = 0; J <= myWorksheet.Table.Rows.Count - 1; J++)

您可以通過該行的Silverlight的電網需要循環代替。

可能只是一件事，這是與示例數據，但不是實際的Excel中的作品：testdata obj = null; this.LstData = new List （）; （int i = 0; i <1000; i ++） { obj = new testdata（）; obj.ID = i; obj.FirstName =「First Name」+ i.ToString（）; obj.LastName =「Last Name」+ i.ToString（）; obj.Address1 =「地址1」+ i.ToString（）; obj.Address1 =「地址2」+ i.ToString（）; obj.City =「City」+ i.ToString（）; obj.Phone =「Phone」+ i.ToString（）; obj.Mobile =「Mobile」+ i.ToString（）; this.LstData.Add（obj）; } – 2012-03-13 19:03:01

你可以粘貼到你的問題更新？很難在這裏閱讀並理解。 – Bryant 2012-03-13 21:15:02
