我使用EPPlus库从datatable创建excel。
这就是我的所作所为:
using (ExcelPackage pck = new ExcelPackage())
{
ExcelWorksheet ws = pck.Workbook.Worksheets.Add("Demo");
ws.Cells["A5:I5"].LoadFromDataTable(dt, true);
ws.DefaultColWidth = 25;
var headerCell = ws.Cells["A5:I5"];
headerCell.Style.Fill.PatternType = ExcelFillStyle.Solid;
headerCell.Style.Fill.BackgroundColor.SetColor(System.Drawing.Color.BurlyWood);
var headerFont = headerCell.Style.Font;
headerFont.Bold = true;
int totalRow = ws.Dimension.End.Row;
int totalCol = ws.Dimension.End.Column;
using (ExcelRange rng = ws.Cells[6,1,totalRow,totalCol])
{
rng.Style.Fill.PatternType = ExcelFillStyle.Solid;
rng.Style.Fill.BackgroundColor.SetColor(System.Drawing.Color.Bisque);
long n = 0;
for (int row = 6; row <= totalRow; row++)
{
for (int col = 1; col <= 9; col++)
{
string colVol = (string)ws.Cells[row, col].Value;
bool isNumeric = long.TryParse(colVol, out n);
if (isNumeric && colVol.Length > 10)
{
//ws.Cells[row, col] //need to apply a css style
}
}
}
}
ws.Cells["A4"].LoadFromText(name);
Response.AddHeader("content-disposition", "inline;filename=" + name + ".xls");
Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
Response.BinaryWrite(pck.GetAsByteArray());
}
我需要将样式应用于电子表格中符合特定条件的某些单元格。
这是在代码在循环中构建表之前的方式:
for (int i = 0; i < dt.Columns.Count; i++)
{
td = new TableCell();
td.Text = dt.Rows[j][i].ToString();
n = 0;
bool isNumeric = long.TryParse(td.Text, out n);
if (isNumeric && td.Text.Length > 10)
td.Attributes.Add("style", @"mso-number-format:\@");
tr.Cells.Add(td);
}
如何从单元格中获取值以使用EPPlus方法检查格式化值的条件?

(反映OP问题编辑和评论的更新答案)
只是做:
ws.Cells[row, col].Style.Numberformat.Format = "@";
这将告诉excel使用文本格式而不是数字格式。
