OleDbDataReader is skipping some values in my CSV file

I have some code that is parsing a CSV that a user uploads.  It's a way from the customer to keep their records up to date.  Anyways, everything seemed to be working fine but I noticed that none of the Canadian Zip Codes were coming over (going from CSV to SQL by the way).  When I parse through, the US zip codes pull fine from the CSV but the Canadian are blank.  I'll post some code that I am using, any help would be appreciated.

Thanks.
string strConn = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + strPath + ";Extended Properties='text;HDR=Yes;FMT=Delimited'";
        OleDbConnection conn = new OleDbConnection(strConn);
        conn.Open();
        try
        {
            OleDbCommand comm = new OleDbCommand("SELECT * from [" + strFilename + "]", conn);
            OleDbDataReader read = comm.ExecuteReader();

            while (read.Read())
            {
                xdlr = "HL" + read[0].ToString();
                xname = read[1].ToString();
                xaddr = read[3].ToString();
                xcity = read[4].ToString();
                xstate = read[5].ToString();
                xzip = read[6].ToString();
                xphone = read[7].ToString();
                xfax = read[8].ToString();
                xemail = read[9].ToString();
            }  
        }

The issue is ado.net takes the ZIPCODE as int type column and canadian zipcodes which has text get skipped. You can use schema.ini file to tell ado.net what is the format and structure of the columns.

Schema.ini file will be like:
[test.csv]
ColNameHeader=True
Format=CSVDelimited
DateTimeFormat=dd-MMM-yyyy
Col1=A DateTime
Col2=B Text Width 100
Col3=C Text Width 100
Col4=D Long
Col5=E Double

Save Schema.ini file in the same folder of test.csv and run the code again....

You can check out this link on using schema.ini file => http://www.aspdotnetcodes.com/Importing_CSV_Database_Schema.ini.aspx

What does one of your CSV lines, containing a Canadian zip, look like?

I took a couple lines out of the file, 1 for a US address/zip and 1 problem child.

May be OLEDB driver takes the ZIPCODE column as integer type...try placing a canadian row as the first line in the csv file as OLEDB might check only the first row to find which type a column is...if the first row is non-integer, then it will treat that column as string and canadian post codes will come up....

I already moved one of the Canadian records to the top of the list with no luck.

I then changed the connection string to indicate there was no Header row, thinking that would trick it into treating the entire Zip Code column as text (assuming it bases off the first record it finds), which in this case would be the value "Zip Code".....still no luck.

string strConn = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + strPath + ";Extended Properties='text;HDR=No;FMT=Delimited'";

Nothing is jumping to mind.  This isn't related to your question, but I think you may want run your code like the attached.
OleDbConnection conn = new OleDbConnection();

try
{
	using(conn = new OleDbConnection(strConn))
	{
		conn.Open();
		//...
	}
}
catch(Exception e){ Console.WriteLine(e.ToString()); }
finally{ conn.Close(); }

Thanks kris_per, I'll give it a shot, knew it was something with integer and text transition but wasn't sure of the resolution.  Thanks again.
