Question

I have a local database and I want to be able to retrieve and insert data into it from C# files. I have read about the INSERT INTO and SELECT FROM SQL commands, but what I want to do is create C# functions that I can call to insert, edit, and retrieve information from the the database. For example:

public void InsertAccountData(string Usrname, string passwd)
{

    INSERT INTO Account(Username, password) VALUES(Usrname, password);

}

I have tried to find an answer, but have not found a solid solution. How would I do this is C#?

Answer 1

public void InsertAccountData(string Usrname, string passwd)
{

    string qry = string.format("INSERT INTO Account(Username, password) VALUES('{0}','{1}')", Usrname, password);
   using (SqlConnection connection = new SqlConnection(connectionString))
   {
    SqlCommand command = new SqlCommand(qry, connection);
        connection.Open();
        SqlDataReader reader = command.ExecuteReader();
        while (reader.Read())
        {
            Console.WriteLine(String.Format("{0}, {1}",
                reader[0], reader[1]));
        }
    }
}

This is how normally we access the DB. Current example is for MSSQL. http://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqlcommand.aspx
