打開XML SDK 2.0以按名稱訪問excel 2010工作表

[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。
