从流中打开电子表格文档 (Open XML SDK)

Question

我正在关注以下有关如何使用 OpenXML SDK 的文章： https://msdn.microsoft.com/en-us/library/office/ff478410.aspx

我有以下代码：

// Open a SpreadsheetDocument based on a stream.
SpreadsheetDocument spreadsheetDocument 
    = SpreadsheetDocument.Open(stream, true);
// Add a new worksheet.
WorksheetPart newWorksheetPart = spreadsheetDocument.WorkbookPart.AddNewPart<WorksheetPart>();
newWorksheetPart.Worksheet = new Worksheet(new SheetData());
newWorksheetPart.Worksheet.Save();

Sheets sheets = spreadsheetDocument.WorkbookPart.Workbook.GetFirstChild<Sheets>();
string relationshipId = spreadsheetDocument.WorkbookPart.GetIdOfPart(newWorksheetPart);

// Get a unique ID for the new worksheet.
uint sheetId = 1;
if (sheets.Elements<Sheet>().Count() > 0)
{
    sheetId = sheets.Elements<Sheet>().Select(s => s.SheetId.Value).Max() + 1;
}

// Give the new worksheet a name.
string sheetName = "Sheet" + sheetId;

// Append the new worksheet and associate it with the workbook.
Sheet sheet = new Sheet() { Id = relationshipId, SheetId = sheetId, Name = sheetName };
sheets.Append(sheet);
spreadsheetDocument.WorkbookPart.Workbook.Save();

// Close the document handle.
spreadsheetDocument.Close();

但我不断收到以下错误：

为什么我会收到此错误消息？

确保您在项目中添加了对 DocumentFormat.OpenXml.dll 的引用。
