sql = "insert into emp values(' + textBox1.Text ')";

This most certainly won't work. You are literally using the string "textBox1.Text" , not its value, in this string.

sql = string.Format("insert into emp values('{0}')", textBox1.Text);

This way is better, but still not "good". Parameterized queries are the best.
