HRESULT中的异常：0X800A03EC

C#读取Excel文件时出现错误“HRESULT中的异常：0X800A03EC”。

代码：

ApplicationClass app = new ApplicationClass();

   app.Visible = false;

   WorkbookClass w = (WorkbookClass)app.Workbooks.Open(this.XlsFileLb.Text,
    Missing.Value, Missing.Value, Missing.Value,
    Missing.Value, Missing.Value, Missing.Value,
    Missing.Value, Missing.Value, Missing.Value,
    Missing.Value, Missing.Value, Missing.Value,
    Missing.Value, Missing.Value);

   object missing = Type.Missing;
   Sheets sheets = w.Worksheets;
   Worksheet datasheet = null;
   foreach (Worksheet sheet in sheets)
   {
    if (sheet.Name == "第一页")
    {
     datasheet = sheet;
     break;
    }
   }
   if (null == datasheet)
   {
    this.MsgLb.Text = "数据文件格式有问题，请检查您的excel文件格式！";
    return;
   }

   Range range = datasheet.get_Range("B3","C184");
   System.Array values = (System.Array)range.Formula;

   if (values != null)
   {
    string[] m_A01Info = new string[5];
    for (int i = 1; i <= 182; i++)
    {
     m_A01Info[0] = values.GetValue(i, 1).ToString();
     m_A01Info[1] = values.GetValue(i, 2).ToString();

    } 
   }
   else
   {
    this.MsgLb.Text += " 读取数据出错！";
   }

   app.Quit();
   app = null;

原因：读取的Excel文件中某个单元格内容太长，红色部分不对，不能直接用range.Formula将EXCEL的内容直接读取到System.Array 。

解决法方：红色部分替换成如下代码

string[,] values = new string[175,2];
   for(int m=0;m<175;m++)
   {
    values[m,0] = Convert.ToString(datasheet.get_Range("B"+ Convert.ToString(2+m),"B"+ Convert.ToString(2+m)).Text);
    values[m,1] = Convert.ToString(datasheet.get_Range("C"+Convert.ToString(2+m),"C"+Convert.ToString(2+m)).Text);
   }
