title: Insert statement won't insert Null value
body: <p>I'm trying to insert a null value into my database from C# like this:</p>
  
  <pre><code>SqlCommand command = new SqlCommand("INSERT INTO Employee
  VALUES ('" + employeeID.Text + "','" + name.Text + "','" + age.Text
          + "','" + phone.Text + "','" + DBNull.Value + "')", connection);
  </code></pre>
  
  <p>DBNull.Value is where a date can be but I would like it to be equal to null but it seems to put in a default date, 1900 something...</p>
