[英]Open XML: Delete entire excel column using column index
我有電子表格中 excel 列的列索引,需要使用此列索引刪除整個列。 我只能使用 Open XML SDK 2.0。
using DocumentFormat.OpenXml.Packaging;
using DocumentFormat.OpenXml.Spreadsheet;
namespace openXMLDemo
{
public class Program
{
public static void Main(string[] args)
{
string fileFullPath = @"path to the excel file here";
string sheetName = "excelsheet name here";
using (SpreadsheetDocument document = SpreadsheetDocument.Open(fileFullPath, true))
{
Sheet sheet = document.WorkbookPart.Workbook.GetFirstChild<Sheets>().Elements<Sheet>().Where(s => s.Name == sheetName).FirstOrDefault();
if (sheet != null)
{
WorksheetPart worksheetPart = (WorksheetPart)document.WorkbookPart.GetPartById(sheet.Id.Value);
// This is where I am struggling....
// finding the reference to entire column with the use of column index
Column columnToDelete = sheet.GetFirstChild<SheetData>().Elements<Column>()
}
}
}
}
}
不幸的是,Open XML 無法選擇列,因此您需要遍歷每一行和其中的單元格以刪除數據:
static void Main(string[] args)
{
string fileFullPath = @"C:\Book1.xlsx";
string sheetName = "Sheet1";
// Specify your column index and then convert to letter format
int columnIndex = 3;
string columnName = GetExcelColumnName(columnIndex);
using (SpreadsheetDocument document = SpreadsheetDocument.Open(fileFullPath, true)) {
Sheet sheet = document.WorkbookPart.Workbook.GetFirstChild<Sheets>().Elements<Sheet>().Where(s => s.Name == sheetName).FirstOrDefault();
if (sheet != null) {
WorksheetPart worksheetPart = (WorksheetPart)document.WorkbookPart.GetPartById(sheet.Id.Value);
// Get all the rows in the workbook
IEnumerable<Row> rows = worksheetPart.Worksheet.GetFirstChild<SheetData>().Elements<Row>();
// Ensure that there are actually rows in the workbook
if (rows.Count() == 0){
return;
}
// Select all the cells from each row where the column letter is equal to index
foreach (Row row in rows) {
var cellsToRemove = row.Elements<Cell>().Where(x => new String(x.CellReference.Value.Where(Char.IsLetter).ToArray()) == columnName);
foreach (var cell in cellsToRemove)
cell.Remove();
}
}
}
}
幫助函數由https://stackoverflow.com/a/182924/5309534提供:
static string GetExcelColumnName(int columnNumber)
{
int dividend = columnNumber;
string columnName = String.Empty;
int modulo;
while (dividend > 0) {
modulo = (dividend - 1) % 26;
columnName = Convert.ToChar(65 + modulo).ToString() + columnName;
dividend = (int)((dividend - modulo) / 26);
}
return columnName;
}
@Shimmy Weitzhandler。 OpenXML 不模擬 Excel。 @Chawin 提出的代碼確實會刪除單元格。 如果您將工作簿作為 zip 存檔打開並打開已從中刪除了單元格的工作表,您將不再看到這些單元格。 但是,如果您在移除的單元格右側有單元格,它們將保留在原處。 要向左移動這些單元格,您需要調整它們的 Cell.CellReference 屬性。 根據工作表的內容,您可能還需要調整其他內容,例如公式、格式、數據驗證、忽略的錯誤等。
