好的記錄,我比許多.NET更加熟悉Java和RnR。我已經修復了一些功能中的一些錯誤,並且在這裏和那裏搜索了一些新的「功能」,但這不是我的專業知識。 OK告誡,這是我的問題,我需要爲我們的網站建立在ASP.NET中的RSS提要。谷歌翻了幾個解決方案,但我用這個作爲一個例子: http://www.aspfree.com/c/a/C-Sharp/Creating-an-RSS-Feed-with-ASP-Net-Written-in-C-Sharp/ASP.NET創建RSS提要,沒有錯誤,但沒有數據
奇怪的是,我得到這一切沒有錯誤,我可以看到,但是當我運行它,我只是得到了一個空白頁面正常工作。我測試了SQL,它工作並返回我想要的行,但我不知道如何診斷它是否連接到數據庫或者它爲什麼不返回任何內容。下面的代碼:
