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();
}
}
我有这个简单的Excel工作表:
问题是当我将此方法称为:
ApplyAutofilter(@".\Test.xlsx", "Foo", "A0:A200");
或者
ApplyAutofilter(@".\Test.xlsx", "Foo", "A1:A200");
当我尝试在以下情况下打开过滤器时,该过滤器未应用且文件损坏:
问题:任何想法如何将此自动文件管理器应用于excel工作表而不损坏它?
最佳答案
发生这种情况是因为您在XML中写入autoFilter
元素的位置。我打开了一个运行了您的代码的文件,并在Open XML Productivity Tool中打开了它。这表明错误是

请注意,这是一个
sequence
,因此项目的顺序很重要。在上面的示例文件中,在autoFilter
元素之后添加了pageMargins
元素,这与上面的架构相反。更改代码以将
autoFilter
元素写入正确的位置可修复您的代码。我不确定这是否是最有效的方法,但这应该可行。从本质上讲,它向后处理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;
}
关于c# - 为什么在此示例中附加AutoFilter会损坏我的excel文件?,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/25398450/
