【问题描述】：

我有这段代码。我想在以Sat 或Sun 开头的行中用绿色为背景着色。我还想用红色字体为小于特定值的单元格着色。

            // Color the row when the day is Saturday or Sunday
            var rang2 = ws.Range["$A$5:$M35"];
            Excel.FormatCondition condition2 = (Excel.FormatCondition)rang2.FormatConditions.Add(
             Excel.XlFormatConditionType.xlExpression,
             Type.Missing, "=OR(TEXT($A1,\"ddd\")=\"Sun\",TEXT($A1,\"ddd\")=\"Sat\")",  Type.Missing, Type.Missing,Type.Missing, Type.Missing, Type.Missing);

           // Color with red
            var rang = ws.Range["$K$5:$L35"];
            Excel.FormatCondition condition = (Excel.FormatCondition)rang.FormatConditions.Add(
         Excel.XlFormatConditionType.xlCellValue,
         Excel.XlFormatConditionOperator.xlLess, "=$L$5", Type.Missing, Type.Missing,
         Type.Missing, Type.Missing, Type.Missing);
condition2.Interior.ColorIndex = 50; condition2.Font.ColorIndex = 1; // Green Background and Black font
condition.Interior.ColorIndex = 0; condition.Font.ColorIndex = 3; // White Background and Red font

问题在于这两种条件格式相互重叠。我尝试更改两种条件格式的顺序，但仍然无法使其正常工作。

使用此设置，第一条规则也将包含红色字体，而第二条规则仅包含白色背景和黑色文本（而不是红色文本）。

是否需要使用条件格式？用 C# 写出逻辑会容易得多
我正在尝试保存到 Excel 文件中。最终文件将发送给某人，所以我需要条件格式。

如果您更改订单，它应该并且确实对我有用。您需要先有 xlCellValue (s)，然后再有 xlExpression。即：此代码按预期工作：

void Main()
{
  var tbl = new System.Data.DataTable();
  new SqlDataAdapter(@"
  WITH  tally ( OrderNo, UniqueId, RandNumber )
        AS (
             SELECT TOP 50000
                    ROW_NUMBER() OVER ( ORDER BY t1.object_id ), 
                    NEWID(),
                    CAST(CAST(CAST(NEWID() AS VARBINARY(4)) AS INT) AS DECIMAL) / 1000
             FROM   master.sys.all_columns t1
             CROSS JOIN master.sys.all_columns t2
           )
  SELECT  OrderNo, 
    DATEADD(DAY, -OrderNo, GETDATE()) as OrnekDate, 
    UniqueId, RandNumber, 
    abs(RandNumber)%100 / 100 as pct
  FROM [tally];", @"server=.\SQLExpress;Database=master;Trusted_Connection=yes;").Fill(tbl);

  object[,] arr = new object[tbl.Rows.Count + 1, tbl.Columns.Count];
  for (int i = 0; i < tbl.Columns.Count; i++)
  {
    arr[0, i] = tbl.Columns[i].Caption;
  }
  for (int i = 0; i < tbl.Rows.Count; i++)
  {
    for (int j = 0; j < tbl.Columns.Count; j++)
    {
      arr[i + 1, j] = tbl.Rows[i][j].ToString();
    }
  }

  // Excel dosya yarat ve arrayi koy
  Microsoft.Office.Interop.Excel.Application xl = new Microsoft.Office.Interop.Excel.Application();
  var workbook = xl.Workbooks.Add();
  xl.Visible = true;

 Worksheet sht = ((Worksheet)workbook.ActiveSheet);
 Range target = (Range)sht.Range[ (Range)sht.Cells[1,1], (Range)sht.Cells[arr.GetUpperBound(0)+1,arr.GetUpperBound(1)+1] ];
 target.Value = arr;
 ((Range)sht.Range["D:D"]).NumberFormat = "$#,##0.0000";
 ((Range)sht.Range["E:E"]).NumberFormat = "0.00%";

  // Color with red
  var rang = sht.Range["$D$5:$D35"];
  FormatCondition condition = (FormatCondition)rang
  .FormatConditions.Add(XlFormatConditionType.xlCellValue,
  XlFormatConditionOperator.xlLess, "0");


  // Color the row when the day is Saturday or Sunday
  var rang2 = sht.Range["$A$5:$M35"];
  FormatCondition condition2 = (FormatCondition)rang2
    .FormatConditions.Add(XlFormatConditionType.xlExpression, Type.Missing, 
      @"=OR(TEXT($A1,""ddd"")=""Sun"",TEXT($A1,""ddd"")=""Sat"")");

  condition2.Interior.ColorIndex = 50; 
  condition2.Font.ColorIndex = 1; // Green Background and Black font
  condition.Interior.ColorIndex = 0; 
  condition.Font.ColorIndex = 3; // White Background and Red font

}
