新手求助 读取excel数据
目的:点击按键读取指定excel表中的A列数据
private void button2_Click(object sender, EventArgs e)
{
Microsoft.Office.Interop.Excel.Application xapp = new Microsoft.Office.Interop.Excel.Application();
Microsoft.Office.Interop.Excel._Workbook xbk;
Microsoft.Office.Interop.Excel._Worksheet xht;
xapp.Visible=true;
xbk = xapp.Workbooks.Open(textBox1.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, );
xht = (Excel.Worksheet)xbk.Sheets[1];
Microsoft.Office.Interop.Excel.Range rng=xht.get_Range("A1",Type.Missing);
}
按了button2,无反应
------解决方案--------------------无反应是什么意思?excel没打开?你看看任务管理器有没有excel进程

------解决方案-------------------- 换种方法,Dataset中去取
public DataSet ExcelToDS(OpenFileDialog openFileDialog1)
{
string strConn = "";
if (openFileDialog1.FileName.EndsWith(".xls"))
{
strConn = "Provider=Microsoft.Jet.OLEDB.4.0;" + "Data Source=" + openFileDialog1.FileName + ";" + "Extended Properties=Excel 8.0;";
}
else if (openFileDialog1.FileName.EndsWith(".xlsx"))
{
strConn = "Provider=Microsoft.ACE.OLEDB.12.0;" + "Data Source=" + openFileDialog1.FileName + ";" + ";Extended Properties=\"Excel 12.0; HDR=No;\"";
// strConn = "Provider=Microsoft.Jet.OLEDB.12.0;" + "Data Source=" + openFileDialog1.FileName + ";Extended Properties=\"Excel 12.0; HDR=No;\"";
