这是我试图访问第一行第一列的代码
string connectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;
Data Source=" + fileName + @";Extended Properties=""Excel 8.0;HDR=NO;""";
string CreateCommand = "SELECT * FROM [Sheet1$]";
OleDbConnection conn = new OleDbConnection(connectionString);
conn.Open();
OleDbCommand cmd = new OleDbCommand(CreateCommand, conn);
// cmd.ExecuteNonQuery();
DbDataReader dr= cmd.ExecuteReader();
int i = 0;
while (dr.Read())
{
string ab = dr.GetValue(i).ToString();
MessageBox.Show(ab);
i++;
}
