Question

I am working with a dbf database. I need to query it to get information back in string format. The dbf file is set up as follows:

Student Name  Student Number  Student Description
HelloWorld      123456789          Present
WorldHello      987654321          Absent

Here is the code i have so far:

    OleDbCommand command;
    OleDbConnection conn = new OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0; Data Source = " + dbfPath + ";Extended Properties=dBase III");
    command = new OleDbCommand("SELECT STUDENTNAME, STUDENTNUMBER, STUDENTDESCRIPTION" + " FROM " + DbfFile + " WHERE " + STUDENTNAME='HelloWorld', conn);

Now i want to get the result as a comma seperated string as follows:

HelloWorld,123456789,Present

How can i do this?

Answer 1

Fetch the results using a DataReader (as explained here), and concatenate the results:

using (var reader = command.ExecuteReader())
{
    while (reader.Read())
    {
        string line = string.Format(
                          "{0},{1},{2}",
                          reader["STUDENTNAME"],
                          reader["STUDENTNUMBER"],
                          reader["STUDENTDESCRIPTION"]);

        ...
    }
}
