向 Excel 工作表中添加公式会导致 HRESULT:0x800A03EC [英] Adding a formula to Excel worksheet results in HRESULT: 0x800A03EC

问题描述

我在网上搜索了合适的解决方案，但找不到任何有用的东西...

I've searched for an appropriate solution online but couldn't find anything helpful...

在 Excel 工作表中，我需要从数据库表中分配一些值，然后在每个值旁边添加一个公式(取决于同一工作簿中的另一个 Excel 工作表).添加数据效果很好，但添加公式会导致错误.

In an Excel worksheet I need to assign some values from a database table and then add a formula to next to each value (depending on another Excel worksheet in the same workbook). Adding the data works perfectly but adding the formula results in an error.

我正在获取数据并将其添加到工作表中，如下所示:

I'm getting the data and adding it to the sheet like this:

using (SqlConnection conn = new SqlConnection("MyConnectionString"))
using (SqlCommand comm = new SqlCommand("SELECT DISTINCT [MyField] FROM [MyTable]", conn)
{
    conn.Open();
    using (SqlDataReader reader = comm.ExecuteReader())
    {
        myStringList.Add("MyField");
        if (reader.HasRows)
            while (reader.Read())
                myStringList.Add(reader.GetString(reader.GetOrdinal("MyField")));
    }
}

workbook.Worksheets.Add(After: workbook.Worksheets[workbook.Sheets.Count]);

for (int counter = 1; counter <= myStringList.Count(); counter++)
    ((Excel.Worksheet)workbook.ActiveSheet).Cells[counter, 1] = myStringList[counter-1];

到目前为止一切顺利.现在我开始解决我的问题.我需要为 B2、B3、... 列中的每个使用过的单元格添加一个公式.困难在于我想用 for 循环来做它，因为公式取决于 A 列.

So far so good. Now I get to my problem. I need to add a formula to the cells B2, B3, ... for every used cell in column A. The difficulty is that I want to do it with a for loop because the formula depends on the column A.

for (int counter = 2; counter <= myStringList.Count(); counter++)
    ((Excel.Worksheet)workbook.ActiveSheet).Range["B" + counter].Formula
        = $"=VLOOKUP(A{counter};MyOtherWorksheet!$B$2:$B${numberOfRows};1;FALSE)";

numberOfRows 是 MyOtherWorksheet 中 B 列的行数(它在调试器中返回正确的数字，所以这不是问题).

numberOfRows is the number of rows in column B in MyOtherWorksheet (it returns the correct number in debugger, so that's not the problem).

但是当我像这样分配公式时，我收到以下异常但没有任何有用的消息:

But when I assign the formula like this, I'm getting the following exception without any helpful message:

结果:0x800A03EC

HRESULT: 0x800A03EC

我尝试将 .Range["B" + counter] 更改为 .Cells[counter, 2] 甚至尝试使用 .FormulaR1C1而不是 .Formula 但我得到了同样的例外.

I tried changing .Range["B" + counter] to .Cells[counter, 2] and even tried using .FormulaR1C1 instead of .Formula but I got the same exception.

我错过了什么?

推荐答案

我发现了问题.我不得不将 .Formula 更改为 .FormulaLocal.

I've found the problem. I had to change .Formula to .FormulaLocal.

.FormulaLocal 的 MSDN 说明:

MSDN description for .FormulaLocal:

返回或设置对象的公式，使用用户语言中的 A1 样式引用.读/写变体.

Returns or sets the formula for the object, using A1-style references in the language of the user. Read/write Variant.

.Formula 的 MSDN 说明:

MSDN description for .Formula:

返回或设置一个 Variant 值，该值以 A1 样式表示法和宏语言表示对象的公式.

Returns or sets a Variant value that represents the object's formula in A1-style notation and in the macro language.
