如何在Excel中顯示圖像

我正在做一個WPF應用程序，使用c＃將我的圖像從我的文件夾導入到excel中。我已經成功地使用微軟的Excel，但我想知道如果用戶沒有安裝微軟的Excel，可以查看文件嗎？下面是我試圖將圖像轉換爲字符串的代碼，但它不顯示在Excel中。如何在Excel中顯示圖像

可能的重複[如何將圖片插入到從C＃應用程序的Excel？]（http://stackoverflow.com/questions/11716873/how-to-insert-a-picture-in-to-excel-from-c-sharp-app） –

嗨，我不想要microsoft excel – user262942

如果用戶的計算機沒有MS excel，我將無法在excel中顯示圖像。 – user262942

因此，如果用戶有Excel，圖像將顯示。如果圖像沒有顯示（沒有Excel），圖像將以其他類似痛苦的形式打開，或者您希望圖像處於任何程序中。
