为什么我得到“；Microsoft][ODBC文本驱动程序]'；(未知)'；不是有效路径”；

根据OP在这里发布的代码（理论上，这应该适用于我所拥有的格式良好的测试文件），我正在尝试将CSV文件的内容分配给DataGridView:

string conStr = @"Driver={Microsoft Text Driver (*.txt; *.csv)};Dbq=" + selectedFile + ";Extensions=csv,txt";
OdbcConnection conn = new OdbcConnection(conStr);
OdbcDataAdapter da = new OdbcDataAdapter("Select * from [" + Path.GetFileName(selectedFile) + "]", conn);
DataTable dt = new DataTable(selectedFile);
da.Fill(dt);
dataGridViewFileContents.DataSource = dt;
da.Dispose();
conn.Close();
conn.Dispose();

在运行我的测试场景时，selectedFile的值为C:''PersianUtil''persianUtilOutput.txt，conStr的值为Driver=｛Microsoft Text Driver（.txt；.csv）｝；Dbq=C:''PersianUtil''persianUtilOutput.txt；扩展名=csv，txt

但在"da.Fill（dt）；"行上，我得到了：

System.Data.Odbc.OdbcException was unhandled
  HResult=-2146232009
  Message=ERROR [HY024] [Microsoft][ODBC Text Driver] '(unknown)' is not a valid path.  Make sure that the path name is spelled correctly and that you are connected to the server on which the file resides.

我在这里做错了什么或没做什么？

如果有更好的方法来做这个/替代方法，我也持开放态度。
