[英]Open XML SDK 2.0 to get access to excel 2010 worksheet by name
我有一個Excel 2010電子表格,其中包含3個名為Sheet1,Sheet2和Sheet3的工作表。
我正在嘗試按名稱獲取對工作表的引用。
我正在使用代碼:
using (SpreadsheetDocument myWorkbook = SpreadsheetDocument.Open(FileName, true))
{
//Access the main Workbook part, which contains all references
WorkbookPart workbookPart = myWorkbook.WorkbookPart;
WorksheetPart worksheetPart = workbookPart.WorksheetParts.Last();
// this gives me Sheet1
SheetData sheetData = worksheetPart.Worksheet.GetFirstChild<SheetData>();
}
我試圖獲得Sheet2的引用,但我找不到這樣做的方法。
我越走越近了,但我還沒到那里:
var x = workbookPart.Workbook.Sheets.Where(s=> s.GetAttribute("name", "").Value == "Sheet2").FirstOrDefault();
這讓我得到了工作表的參考,但沒有給工作表上的數據
謝謝
你真正想要的是WorksheetPart
,它包含你正在尋找的SheetData
。 抓取Workbook
下的Sheets
只會為您提供有關工作表的某些元數據。 這里是如何抓住這樣的例子WorksheetPart
(隨意添加你認為合適的錯誤檢查,因為我承擔sheetName
已經通過調用存在, First
,而不是FirstOrDefault
)
public WorksheetPart GetWorksheetPart(WorkbookPart workbookPart, string sheetName)
{
string relId = workbookPart.Workbook.Descendants<Sheet>().First(s => sheetName.Equals(s.Name)).Id;
return (WorksheetPart)workbookPart.GetPartById(relId);
}
然后只需使用上面的代碼來獲取正確的SheetData引用,您就可以從那里找到所需的數據。
下面是一些代碼,用於處理具有特定選項卡或工作表名稱的電子表格,並將其轉儲為CSV。 (我選擇了一個管道而不是逗號)。
我希望從單元格中獲取值更容易,但我認為這是我們所堅持的。 您可以看到我參考了MSDN文檔,其中包含了大部分代碼。 這是微軟推薦的。
