請大家幫幫我嗎?當我點擊查看按鈕,如果它是PDF文件,它顯示在瀏覽器中,但如果它是.docx,doc,.xlsx,..它會直接下載。我怎樣才能在瀏覽器中顯示該文件?
感謝您的答覆。你能解釋一下如何在webapplicaion.i中使用folderbrowserDialog,你的代碼是windows應用程序。如果我去使用System.Windows.Form我有一些錯誤。因爲我使用web controls.i需要web應用程序的解決方案 – user3300574
@ user3300574,是的,它是WinForm的語法,我建議你在帖子中添加'web application'標籤,以便這個領域的專家可以幫助你。請在設法解決問題時發佈答案。謝謝。 – user3165438
