嗨，我使用以下方法来应用自动筛选器：
public static void ApplyAutofilter(string fileName, string sheetName, string reference)
{
using (SpreadsheetDocument document = SpreadsheetDocument.Open(fileName, true))
{
IEnumerable<Sheet> sheets = document.WorkbookPart.Workbook.GetFirstChild<Sheets>().Elements<Sheet>().Where(s => s.Name == sheetName);
var arrSheets = sheets as Sheet[] ?? sheets.ToArray();
string relationshipId = arrSheets.First().Id.Value;
var worksheetPart = (WorksheetPart)document.WorkbookPart.GetPartById(relationshipId);
var autoFilter = new AutoFilter() { Reference = reference };
worksheetPart.Worksheet.Append(autoFilter);
worksheetPart.Worksheet.Save();
}
}
而且我有这个简单的Excel工作表：
<< img src =“ https://image.soinside.com/eyJ1cmwiOiAiaHR0cHM6Ly9pLnN0YWNrLmltZ3VyLmNvbS9HYThqSC5qcGcifQ==” alt =“在此处输入图像描述”>
问题是当我将此方法称为：
ApplyAutofilter(@".\Test.xlsx", "Foo", "A0:A200");
或
ApplyAutofilter(@".\Test.xlsx", "Foo", "A1:A200");
未应用过滤器，并且在以下情况下尝试打开它时文件被损坏：
<< img src =“ https://image.soinside.com/eyJ1cmwiOiAiaHR0cHM6Ly9pLnN0YWNrLmltZ3VyLmNvbS9PTnM5cS5qcGcifQ==” alt =“在此处输入图像描述”>
问题：知道如何将此自动文件管理器应用于Excel工作表而不损坏它吗？
这是由于您在XML中编写autoFilter元素而导致的[[where。我打开了一个运行了您的代码的文件，并在Open XML Productivity Tool中将其打开。这表明错误是

注意，它是sequence，因此项目的顺序很重要。在我的示例文件中，在autoFilter元素之后添加了pageMargins元素，这与上述架构相反。更改代码以将
autoFilter元素写入正确的位置会修复您的代码。我不确定这是否是最有效的方法，但这应该可行。本质上，它向后推动workbook的子元素，直到找到autoFilter之后的第一个元素。一旦发现它使用InsertAfter方法将autoFilter插入正确的位置：
public static void ApplyAutofilter(string fileName, string sheetName, string reference) { using (SpreadsheetDocument document = SpreadsheetDocument.Open(fileName, true)) { IEnumerable<Sheet> sheets = document.WorkbookPart.Workbook.GetFirstChild<Sheets>().Elements<Sheet>().Where(s => s.Name == sheetName); var arrSheets = sheets as Sheet[] ?? sheets.ToArray(); string relationshipId = arrSheets.First().Id.Value; var worksheetPart = (WorksheetPart)document.WorkbookPart.GetPartById(relationshipId); var autoFilter = new AutoFilter() { Reference = reference }; OpenXmlElement preceedingElement = GetPreceedingElement(worksheetPart); worksheetPart.Worksheet.InsertAfter(autoFilter, preceedingElement); worksheetPart.Worksheet.Save(); } } public static OpenXmlElement GetPreceedingElement(WorksheetPart worksheetPart) { List<Type> elements = new List<Type>() { typeof(Scenarios), typeof(ProtectedRanges), typeof(SheetProtection), typeof(SheetCalculationProperties), typeof(SheetData) }; OpenXmlElement preceedingElement = null; foreach (var item in worksheetPart.Worksheet.ChildElements.Reverse()) { if (elements.Contains(item.GetType())) { preceedingElement = item; break; } } return preceedingElement; }
OpenXmlElement preceedingElement = GetPreceedingElement(worksheetPart);
worksheetPart.Worksheet.InsertAfter(autoFilter, preceedingElement);
