两个程序试图读取excel一个成功一个失败相同的代码

Question

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++;
                }
            }
        }
    }

计划2

private static DataTable GetInvoiceItems(string filepath)
{
        DataTable dt = new DataTable();
        string excelConString = @"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(excelConString))
        {
            OleDbDataAdapter ada = new OleDbDataAdapter("SELECT [F1], [F2], [F3], [F4], [F5] FROM [Sheet1$]", conn);
            conn.Open();
            ada.Fill(dt);
        }
        return dt;
}

现在奇怪的是第一个程序完全在同一台PC上运行,而第二个程序得到一个错误,说PC上没有可安装的ISAM.有什么建议？

Answer 1

尽管你的断言他们都是一样的,如果你仔细观察他们就不是.看看你的连接字符串......

计划1

"... Excel 8.0;IMEX=1;HDR=NO;TypeGuessRows=1;ImportMixedTypes=Text\\"

计划2

"... Excel=8.0;IMEX=1;HDR=NO;TypeGuessRows=1;ImportMixedTypes=Text\\"

不应该有=在Excel 8.0在程序2.
