title: ExecuteNonQuery() doesn't work
body: <p>Every time I try to run my code, I get this exception:</p>
  
  <blockquote>
    <p>An unhandled exception of type 'System.Data.SqlClient.SqlException'
    occurred in System.Data.dll</p>
    
    <p>Additional information: Incorrect syntax near ')'.</p>
  </blockquote>
  
  <p>Tried multiple workarounds, but I never get past the <code>ExectueNonQuery</code> line. Can someone tell me what's wrong with it? </p>
  
  <pre><code>private void button1_Click(object sender, EventArgs e)

      SqlConnection con = new SqlConnection(@"Data Source=CHARLIE-PC\MSSQLSERVER1;Initial Catalog=Tema;Integrated Security=True;");
      con.Open();
  
      SqlCommand cmd = new SqlCommand("INSERT INTO Fisier (idFisier, Nume, idFolder) VALUES ('"+idFis.Text+ "','"+ numeFis.Text + "','" +idFoldFis.Text +"',)", con);
  
      cmd.ExecuteNonQuery();
      con.Close();
  }
