我有一列带有日期的列,我想有条件地为任何早于2周的单元格着色为黄色,而将早于90天的单元格着色为红色。我不知道该怎么做。

应该能够像添加其他条件一样添加条件。您可以在excel中使用TODAY()
函数,然后减去:
[TestMethod]
public void Conditional_Formatting_Date()
{
//https://stackoverflow.com/questions/56741642/epplus-two-color-conditional-date-format
var file = new FileInfo(@"c:\temp\Conditional_Formatting_Date.xlsx");
if (file.Exists)
file.Delete();
//Throw in some data
var dataTable = new DataTable("tblData");
dataTable.Columns.AddRange(new[] {
new DataColumn("Col1", typeof(DateTime)),
new DataColumn("Col3", typeof(string))
});
var rnd = new Random();
for (var i = 0; i < 100; i++)
{
var row = dataTable.NewRow();
row[0] = DateTime.Now.AddDays(-rnd.Next(1, 100));
row[1] = $"=TODAY() - A{i +1}";
dataTable.Rows.Add(row);
}
//Create a test file
using (var package = new ExcelPackage(file))
{
//Make the stylesheet
var ws = package.Workbook.Worksheets.Add("table");
var range = ws.Cells[1, 1].LoadFromDataTable(dataTable, false);
ws.Column(1).Style.Numberformat.Format = "mm-dd-yy";
ws.Column(1).AutoFit();
//Add the calc check
var count = 0;
foreach (DataRow row in dataTable.Rows)
ws.Cells[++count, 2].Formula = row[1].ToString();
//Add the conditions - order matters
var rangeA = range.Offset(0, 0, count, 1);
var condition90 = ws.ConditionalFormatting.AddExpression(rangeA);
condition90.Style.Font.Color.Color = Color.White;
condition90.Style.Fill.PatternType = ExcelFillStyle.Solid;
condition90.Style.Fill.BackgroundColor.Color = Color.Red;
condition90.Formula = "TODAY() - A1> 90";
condition90.StopIfTrue = true;
var condition14 = ws.ConditionalFormatting.AddExpression(rangeA);
condition14.Style.Font.Color.Color = Color.Black;
condition14.Style.Fill.PatternType = ExcelFillStyle.Solid;
condition14.Style.Fill.BackgroundColor.Color = Color.Yellow;
condition14.Formula = "TODAY() - A1> 14";
package.Save();
}
}
哪个在输出中给出:

我假设您在记录中具有日期列的列号和行数。同样,以下循环是假设第一行是您的列标题,并且记录从第二行开始。相应地更改循环计数器的初始化和分配。
int rowsCount; //get your no of rows
int dateColNumber; //Assign column number in excel file of your date column
string cellValue;
DateTime dateValue;
DateTime today = DateTime.Now;
double daysCount;
for(int i=1;i<rowsCount;i++)
{
cellValue = ws.Cells[i + 1, dateColNumber].Text.ToString(); //First row is header start from second
if(DateTime.TryParse(cellValue,out dateValue))
{
daysCount = (today - dateValue).Days;
if(daysCount>90)
{
ws.Cells[i + 1,dateColNumber].Style.Fill.PatternType = OfficeOpenXml.Style.ExcelFillStyle.Solid;
ws.Cells[i + 1,dateColNumber].Style.Fill.BackgroundColor.SetColor(System.Drawing.Color.Red);
}
else if(daysCount>14)
{
ws.Cells[i + 1, dateColNumber].Style.Fill.PatternType = OfficeOpenXml.Style.ExcelFillStyle.Solid;
ws.Cells[i + 1, dateColNumber].Style.Fill.BackgroundColor.SetColor(System.Drawing.Color.Yellow);
}
}
}
