C# Windows Forms: SqlConnection keyword not supported, connection timeout

Question

Just learning how to create an Windows Forms application via Tom Owsiak C# Windows Forms video tutorials and I'm stuck at the database project (contacts management system) which requires to store data to a database.

I've been following his every single step yet somehow manage to mess up the application writing process. The error happen at the line

SqlConnection conn = new SqlConnection(connString);

Have been searching stackExchange for a while now and try possible solution but still couldn't work it out.

// error occurs here, stated key word not supported, connection timeout
using (SqlConnection connectforfucksake = new SqlConnection(connString)) 
{
    try
    {
        connectforfucksake.Open(); // open the connection

        // create the new SqlCommand object
        command = new SqlCommand(insert, connectforfucksake); 

        command.Parameters.AddWithValue(@"Data_Added", dateTimePicker1.Value.Date);
        command.Parameters.AddWithValue(@"Company", txtCompany.Text);
        command.Parameters.AddWithValue(@"Website", txtWebsite.Text);
        command.Parameters.AddWithValue(@"Title", txtTitle.Text);
        command.Parameters.AddWithValue(@"First_Name", txtFName.Text);
        command.Parameters.AddWithValue(@"Last_Name", txtLName.Text);
        command.Parameters.AddWithValue(@"Address", txtAddress.Text);
        command.Parameters.AddWithValue(@"City", txtCity.Text);
        command.Parameters.AddWithValue(@"State", txtState.Text);
        command.Parameters.AddWithValue(@"Postal_Code", txtPostalCode.Text);
        command.Parameters.AddWithValue(@"Mobile", txtMobile.Text);
        command.Parameters.AddWithValue(@"Note", txtNote.Text);

        command.ExecuteNonQuery();   // pushing whatever in the form into table
    }
    catch (Exception ex)
    {
       MessageBox.Show(ex.Message); // show the unforeseen error
    }
}

Expected application to take result and then store them into database but it seem like the SqlConnection object instantiate is causing the error.

It sounds like your connection string is simply wrong; most likely, you meant "Connect Timeout" rather than "connection timeout". A basic connection string that includes a connect timeout might be something like:

Data Source=.;Initial Catalog=master;Integrated Security=True;Connect Timeout=42
