我有两个彼此无关的程序,但是他们有一个相同的方法,他们尝试从excel文件中读取行.

计划1

    public DataTable GetExcelInfo(string filepath)
    {
        DataTable datatab = new DataTable();
        try
        {
            string connectionString = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + filepath + ";Excel 8.0;IMEX=1;HDR=NO;TypeGuessRows=1;ImportMixedTypes=Text\\";
            using (OleDbConnection conn = new OleDbConnection(connectionString))
            {
                conn.Open();
                OleDbCommand cmd = new OleDbCommand("SELECT Format([F1], \"#\"), Format([F2], \"#\"), Format([F3], \"#\") FROM [Sheet1$]", conn);
                OleDbDataReader reader = cmd.ExecuteReader();
                while (reader.Read())
                {
                    string[] values = new string[3];                        
                    values[0] = reader.GetString(0);
                    values[1] = reader.GetString(1);
                    values[2] = reader.GetString(2);

                    DataRow dr = datatab.NewRow();
                    dr.ItemArray = values;
                    datatab.Rows.InsertAt(dr, i);
                    i++;
                }
            }
        } …
