打開由XML創建的Excel文件時出錯

Question

我已經開始使用Open XML創建Excel文件，以便向其中添加一些數據。我所包含的示例文件是我在網上找到的示例的修改版本。它創建了excel文件，但是當我嘗試打開它時，它給了我三個錯誤。我懷疑最後兩個錯誤是由於爲標題單元添加StyleIndex，但是當我打開任何Excel文件時，最近出現第一個錯誤。

1-無法使用對象鏈接和嵌入。

2- Excel在'SheetPInfo.xlsx'中發現不可讀的內容。是否要恢復此工作簿的內容？如果您信任此工作簿的來源，請單擊是。

3-Excel能夠通過修復或刪除不可讀的內容來打開文件。 修復記錄：/xl/worksheets/sheet.xml中的單元信息部分

在關閉最後一條錯誤消息後，我還獲取了文件中的數據/數組，但StyleIndex（大字體）未出現在標題單元格中'姓'。

什麼可能是錯的？當我在線搜索時，行的順序對於Excel非常重要，所以我想也許我的StyleIndex相關行出錯了。

任何幫助將不勝感激。

最後，我發現了一個解決方案，可以將我的數據放入Excel文件中，而不會出現任何錯誤！我從http://www.codeproject.com/Tips/765068/Complete-Open-XML-Spreadsheet-in-VB 下載了.zip文件，由於它的Visual Studio版本與我的版本不一樣，所以我必須從下載的文件夾中複製openXMLExcelCreator類並將其粘貼到我的項目中。然後，我將其'doStuff'子添加到我的網頁中，並使用不同的名稱進行修改，以顯示我想要的標題和數據庫中的數據。爲了便於搜索，我還設法改變了標題行和替代行的背景。
