Conditional Formatting on cell values

Question

I'm currently trying to set conditional formatting on an excel document. I'm currently using interop to work with the document.

The column contains time/date values and I'm trying to create a condition that highlights values over 15 minutes.

This is what I've got so far.

range = xlWorksheet.get_Range("F2", "F" + RC);
Excel.FormatCondition condition = (Excel.FormatCondition)range.FormatConditions.Add(
        XlFormatConditionType.xlExpression, 
        Type.Missing,
        "> =0,0104166666666667",
        Type.Missing,
        Type.Missing,
        Type.Missing,
        Type.Missing,
        Type.Missing);

condition.Interior.ColorIndex = 3; // Red

The range selects the correct column, I think the issue is i'm not building the right formula.

This is what the condinonal formatting looks like when I do it in excel.

This is what my formula looks like when I try replicate it with my application.

   ActiveWindow.ScrollColumn = 2
    ActiveWindow.ScrollColumn = 3
    Range("F1:F11").Select
    Selection.FormatConditions.Add Type:=xlCellValue, Operator:=xlGreater, _
        Formula1:="=0,0104166666666667"
    Selection.FormatConditions(Selection.FormatConditions.Count).SetFirstPriority
    With Selection.FormatConditions(1).Font
        .Color = -16383844
        .TintAndShade = 0
    End With
    With Selection.FormatConditions(1).Interior
        .PatternColorIndex = xlAutomatic
        .Color = 13551615
        .TintAndShade = 0
    End With
    Selection.FormatConditions(1).StopIfTrue = False
End Sub

This is the macro equivalent of what I'm trying to do in C#.

Answer 1

Excel.FormatCondition condition = (Excel.FormatCondition)range.FormatConditions.Add(Excel.XlFormatConditionType.xlCellValue, Excel.XlFormatConditionOperator.xlGreater, "=0,0104166666666667", Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);

将公式条件更改为xlCellValue可以解决问题。
