Question

我用C＃和Microsoft.Office.Interop.Excel编写代码。在生成的下拉列表中，可以在“确定”，“删除”，“其他”之间进行选择。现在，我希望如果选择“删除”，该单元格将变为红色。我试图用Excel.FormatCondition来做到这一点：

Excel.FormatCondition condition = mysheet.get_Range("J2:J10",
    Type.Missing).FormatConditions.Add(Type:Excel.XlFormatConditionType.xlTextString,
    Operator: Excel.XlFormatConditionOperator.xlEqual, Formula1: "=\"delete\"");
condition.Interior.ColorIndex = 3;

使用此代码，我得到一个错误：

System.Runtime.InteropServices.COMException：'来自HRESULT的异常： 0x800A03EC'

Answer 1

老问题，但希望这可能对其他人有所帮助。当您将类型设置为 Type:Excel.XlFormatConditionType.xlTextString 时，您需要设置 String: 和 TextOperator: 参数，而不是问题中所示的 Operator: 和 Formula1:。

修复代码：

FormatConditions.Add(Type:Excel.XlFormatConditionType.xlTextString,
    TextOperator: Excel.XlContainsOperator.xlContains, String: "delete");

Answer 2

我找到了解决方案。很简单。我必须使用XlFormatConditionType.xlCellValue而不是TextString：

//Drop-down List
var list = new System.Collections.Generic.List<string>();

list.Add("okay");
list.Add("delete");
list.Add("else (Comment)");
var flatList = string.Join(",", list.ToArray());

var celldd = (Excel.Range)mysheet.Cells[row_counter, 10];

celldd.Validation.Delete();
try
{
    int type = celldd.Validation.Type;
    Console.WriteLine("The validation have already been added");
}
catch (System.Runtime.InteropServices.COMException)
{
    celldd.Validation.Add(
    Excel.XlDVType.xlValidateList,
    Excel.XlDVAlertStyle.xlValidAlertInformation,
    Excel.XlFormatConditionOperator.xlBetween,
    flatList, misValue);
 }
 celldd.Validation.InCellDropdown = true;
 celldd.Validation.IgnoreBlank = true;
 celldd.Locked = false;

 celldd.Value2 = "Choose";
 celldd.Interior.Color = ColorTranslator.ToOle(Color.Plum);

 //Conditional Formatting
 Excel.FormatCondition condition1 = mysheet.get_Range("J2:J10",
        Type.Missing).FormatConditions.Add(Excel.XlFormatConditionType.xlCellValue, Excel.XlFormatConditionOperator.xlEqual, "=\"delete\"", misValue, misValue, misValue, misValue, misValue);
 condition1.Interior.ColorIndex = 3;  //red

 Excel.FormatCondition condition2 = mysheet.get_Range("J2:J10",
        Type.Missing).FormatConditions.Add(Excel.XlFormatConditionType.xlCellValue, Excel.XlFormatConditionOperator.xlEqual, "=\"okay\"", misValue, misValue, misValue, misValue, misValue);
 condition2.Interior.ColorIndex = 43; //green

Excel.FormatCondition condition3 = mysheet.get_Range("J2:J10",
        Type.Missing).FormatConditions.Add(Excel.XlFormatConditionType.xlCellValue, Excel.XlFormatConditionOperator.xlEqual, "=\"else (Comment)\"", misValue, misValue, misValue, misValue, misValue);
condition3.Interior.ColorIndex = 44;  //yellow
