Question

我只是想编辑一个已写入文本的电子表格，将文本更改为空白。

然而它无法正常工作。该方法似乎无能为力。

我的代码是：

public static void ClearCells(string SpreadsheetFilePath)
{
    var SpreadsheetPath = new FileInfo(SpreadsheetFilePath);
    var package = new ExcelPackage(SpreadsheetPath);
    ExcelWorkbook workBook = package.Workbook;
    if (workBook != null)
    {
        if (workBook.Worksheets.Count > 0)
        {
            ExcelWorksheet currentWorksheet = workBook.Worksheets.First();
            currentWorksheet.SetValue(1, 1, "hello123");
        }
    }
}

没有运行时错误。它运行，完成，电子表格不变。我不知道为什么。

完成编辑文件后，只需致电package.Save();即可。

var SpreadsheetPath = new FileInfo(@"C:\temp\abc.xlsx");
var package = new ExcelPackage(SpreadsheetPath);
ExcelWorkbook workBook = package.Workbook;
if (workBook != null)
{
    if (workBook.Worksheets.Count > 0)
    {
        ExcelWorksheet currentWorksheet = workBook.Worksheets.First();
        currentWorksheet.SetValue(1, 1, "hello123");
    }
}

package.Save();  // <========= MISSING IN YOUR CODE

尝试这样的事情：

public static void ClearCells(string SpreadsheetFilePath)
{
    var excelFile = new FileInfo(SpreadsheetFilePath);
    var excelPack = ExcelPackage(excelFile);

    var workSheet = excelPack.Workbook.Worksheets.Add("Content"); // New worksheet           
    workSheet.Cells[1, 1].Value = "hello123";

    excelPack.Save();
}

如何使用SetCellValue代替SetValue？

public static void ClearCells(string SpreadsheetFilePath)
{

var SpreadsheetPath = new FileInfo(SpreadsheetFilePath);
var package = new ExcelPackage(SpreadsheetPath);
ExcelWorkbook workBook = package.Workbook;
if (workBook != null)
{
    if (workBook.Worksheets.Count > 0)
    {
        ExcelWorksheet currentWorksheet = workBook.Worksheets.First();
        currentWorksheet.SetCellValue(1, 1, "hello123");
    }
}
}
