如何使用 Excel Interop 检索与基于引用另一个 Excel 工作表的公式的 Excel 单元格关联的值？

Question

I am properly able to get the values of Excel cells using Excel interop with the following method:

public string ReadCell(object row, object column)
{
    try
    {
        if (m_Worksheet.Cells[row][column].Value != null)
        {
            return Convert.ToString(m_Worksheet.Cells[row][column].Value2);
        }
     }
     catch
     {
         //
     }
      
        return string.Empty;
    }
}

The above code works for ordinary text or number values.

When it is a formula -- for example, when I use a formula as following no text or value will appear: ='Data Selection'!B4

The actual value of this cell is "Community Bank"

I ended up solving this problem. The else if case is actually what I was originally using, but it previously threw an exception in some instances (I cannot remember what the exact exception was). I will go back later and improve my answer.

public string ReadCell(object row, object column)
{
    try
    {
        if (m_Worksheet.Cells[row][column].Value != null)
        {
            return Convert.ToString(m_Worksheet.Cells[row][column].Value2);
        }
        else if (m_Worksheet.Cells[row, column].Value != null)
        {
            return Convert.ToString(m_Worksheet.Cells[row, column].Value2);
        }
     }
     catch
     {
         //
     }

     return string.Empty;
}
