Trouble with Insert Into .dbf file

This code does not save any data in the dbf file. What is wrong here? Here is the code with the recommended changes. Thank you.

string connectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\TEMP;Extended Properties=dBase IV"; 
        using (OleDbConnection connection = new OleDbConnection(connectionString)) 
        using (OleDbCommand command = connection.CreateCommand()) 
        { 
            connection.Open(); 
            command.CommandText = @"CREATE TABLE TEST (Id Text, Changed Text, Tacos Text)"; 
            command.ExecuteNonQuery(); 
        }
        using (OleDbConnection connection2 = new OleDbConnection(connectionString))
        using (OleDbCommand command2 = connection2.CreateCommand())
        {
            connection2.Open();
            command2.CommandText = @"Insert into TEST (Id, Changed, Tacos) VALUES ('One','Two','Three')";

            try
            {
                command2.ExecuteNonQuery();
            }
            catch (Exception ee) 
            {
                MessageBox.Show(ee.ToString());
            }
        }

Not positive, but looking at your connection, you are connecting to the root of C:.... bad... It could just be a matter of permissions and not able to write at the root directory.'

I would suggest creating your connection to SOME sub folder, even if its just

C:\MyDBFTesting\

After that, see if the "CREATE TABLE" result actually worked and you can see the "test.dbf".

Finally, put your executeNonQuery() in a try/catch

try
{
   command2.ExecuteNonQuery()
}
catch( Exception e )
{
   string x = e.Message;
}

put a break point at the catch and step into... see what OTHER element / messages may be in the "e" exception object to provide more possible answers for you.

Seeing the context of ".dbt" (which indicates more free-form text rather than fixed / standard types), i would change your create to explicitly identify CHARACTER of fixed size capacity... something like

create table Test ( ID C(10), Changed C(10), Tacos C(10) )

C = Character and 10 is the max size that would be allowed in the column. Other data types, such as I = int, D = date only, T = date/time, L = logical, etc. These are "known" types which provide a strict structure. The TEXT is freeform and its content goes into the .dbt file, but there SHOULD be a corresponding record, but otherwise not appearing to show up.

Then, your insert command would still work identically.
