我将一些数据收集到DataGridView＆＃34; dataGridView2＆＃34;我想将其导出到excel中的工作表但我收到HRESULT错误，错误代码为{{1以下是代码：
0x800A03EC请帮助我还能做些什么，因为我认为上面的代码是正确的，我不知道为什么会出现这样的错误private void button2_Click(object sender, EventArgs e)
{
Microsoft.Office.Interop.Excel.Application app = new.Microsoft.Office.Interop.Excel.Application();
Microsoft.Office.Interop.Excel.Workbook workbook = app.Workbooks.Open(@path);
Microsoft.Office.Interop.Excel.Worksheet worksheet = workbook.ActiveSheet;
//Couunt the number cells in the
//datagridview asign it to an integers
//variable
int rHtcount = dataGridView2.Rows.Count;
int iii = 0;
//put each values from each cells of the
//datagridview into each cell in the
//destination
for(; iii < rHtcount; iii++)
{
worksheet.Cells[iii + 2, "H"].Value = dataGridView2.Rows[iii].Cells[0].Value;
}
app.Visible = true;
workbook.Close();
}
答案 0 :(得分：0)
尝试替换new.Microsoft.Office.Interop.Excel.Application();
与new Microsoft.Office.Interop.Excel.Application();
HTH !!!
