OpenFileDialog dialog = new OpenFileDialog();
if (dialog.ShowDialog() == DialogResult.OK)
{
string strConnection = "Provider=Microsoft.Jet.OLEDB.4.0;Extended Properties='Excel 8.0;HDR=YES;IMEX=1;';Data Source=" + dialog.FileName + ";";
OleDbConnection connection = new OleDbConnection(strConnection);
connection.Open();
try
{
string str = "Select * from [Sheet1$]";
OleDbCommand myCommand = new OleDbCommand(str, connection);
OleDbDataReader myReader;
myReader = myCommand.ExecuteReader();
while (myReader.Read())
{
MessageBox.Show(myReader.GetString(0));
}
myReader.Close();
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
finally
{
connection.Close();
}
}
一个小测试 ,实践证明是可以的
