使用表达式 EPPlus 格式化条件

Question

我正在使用EPPlus创建Excel，并进行条件格式设置。我使用C#代码进行条件格式设置，但它没有起作用。

请检查下面的代码并告诉我哪里出错了：

ExcelPackage pck = new ExcelPackage();
var ws = pck.Workbook.Worksheets.Add("Sample1");
var _formatRangeAddress = new ExcelAddress("H16:K31,H33:K44,H46:K57,H59:K69,H71:K73");
string _statement = "=AND(COUNTA(H16:H16)<2,COUNTA(H16:K16)>0)";
var _cond4 = ws.ConditionalFormatting.AddExpression(_formatRangeAddress);
_cond4.Style.Fill.PatternType = OfficeOpenXml.Style.ExcelFillStyle.Solid;
_cond4.Style.Fill.BackgroundColor.Color = Color.Green;
_cond4.Formula = _statement;
pck.SaveAs(Response.OutputStream);
Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
Response.AddHeader("content-disposition", "attachment;  filename=Sample1.xlsx");

Answer 1

在公式字符串中不要以=开头：

string _statement = "AND(COUNTA(H16:H16)<2,COUNTA(H16:K16)>0)";
[...]
_cond4.Formula = _statement;

这里提到了解决方案：使用EPPlus进行表达式条件格式化。

Please try this:

ExcelPackage pck = new ExcelPackage();
var ws = pck.Workbook.Worksheets.Add("Sample1");
var _formatRangeAddress = new ExcelAddress("H16:K31,H33:K44,H46:K57,H59:K69,H71:K73");
string _statement = "AND(COUNTA(H16:H16)<2,COUNTA(H16:K16)>0)";
var _cond4 = ws.ConditionalFormatting.AddExpression(_formatRangeAddress);
_cond4.Style.Fill.PatternType = OfficeOpenXml.Style.ExcelFillStyle.Solid;
_cond4.Style.Fill.BackgroundColor.Color = Color.Green;
_cond4.Formula = _statement;
pck.SaveAs(Response.OutputStream);
Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
Response.AddHeader("content-disposition", "attachment;  filename=Sample1.xlsx");
