如何在C＃应用程序中使用DSN文件？

Question

This is my old code.

conn = new System.Data.Odbc.OdbcConnection();
conn.ConnectionString = @"DSN=dBase Files";

It throws an Error: (I think my old code might still work on 32 bit machines, but I am on 64 now)

"[Error] [IM002] [Microsoft] [ODBC Driver Manager] Data source name not found and no default driver specified"

All my searches told me to use SysWow64/odbcad32.exe to create a .DSN file. Now I created the DSN file, How can I modify this line, conn.ConnectionString = @"DSN=dBase Files"; , to point to the .DSN file I saved on disk?

Answer 1

As far as I recall, I had to set up the DSN in ODBC Data Sources under Administrative Tools, but that was around the turn of the century.

This might help: FILEDSN=c:\\myDsnFile.dsn;Uid=myUsername;Pwd=;

So something like:

conn = new System.Data.Odbc.OdbcConnection();
conn.ConnectionString = @"FILEDSN=C:\path\to\dsn\file\here.dsn;Uid=myUsername;Pwd=;";

From here .
