DBF to CSV conversion using C#

I am converting a dbf file into csv file using C#. My program is working fine for file having fewer columns in dbf file. If the dbf file has more than 255 columns, I am getting the error "FILENAME" is not a table.

I am using Visual foxpro OLEDB friver. I downloaded drivers from


I tried with Microsoft dBase ODBC and OLE DB drivers. Both are giving the errors.


The Microsoft Jet database engine could not find the object 'Temp.dbf'.  Make sure the object exists and that you spell its name and the path name correctly

ERROR [42S02] [Microsoft][ODBC dBase Driver] The Microsoft Jet database engine could not find the object "Temp.dbf'.  Make sure the object exists and that you spell its name and the path name correctly

File Temp.dbf is existing.

Initially, I tried with these drivers. But I was getting this errors and then tried with visual foxpro drivers. It is working with other files except one file which has 261 columns.

Connection strings are :

string inputDir = @"C:\Temp_DBF"   //my dbf file location
string fileName = "Temp.dbf";      // Tried with Temp also.
string dataSource = inputDir + "\\" + fileName;

string strConn = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + inputDir + ";Extended Properties=dBASE IV";

//string strConn = @"Driver={Microsoft dBASE Driver (*.dbf)};DriverID=277;Dbq=" + inputDir + ";";
//string strConn = @"Provider=VFPOLEDB.1;Data Source=" + dataSource + ";Persist Security Info=False;";

I tried with dBase 5.0 also, I am getting the error "Could Not Find Installable ISAM"

You can find more information here...

Any Help.
Thanks In Advance!!!

In FoxPro, a standalone table has a limit of 255 fields (or 254 if one or more of your fields is allowed null values). If you open a dbf with more than 255 fields in FoxPro, it comes back with a "not a table" error.
