title: "Operator '+' cannot be applied to operands of type 'object' and 'object'" When populating a list box
body: <p>I'm trying to popular a list box in a Visual C# Form Application on Visual Studio 2012, however when I go to add the items to the list box, it claims the error:</p>
  
  <p><strong>Error 1   Operator '+' cannot be applied to operands of type 'object' and 'object'</strong></p>
  
  <p>How do I write code to add in 3 objects using the + operator? </p>
  
  <p>I've never used a compact SQL database before, only through web development so I am new to Visual Studio Databases, so most probably a rookie error. Can anyone point me in the right direction?</p>
  
  <p><strong>populateListBox</strong></p>
  
  <pre><code>public void populateListBox()
          {
              String query = "SELECT Bug_Code, Bug_Description, Bug_Author FROM tblBugs";
              SqlCeCommand mySqlCommand = new SqlCeCommand(query, mySqlConnection);
              try
              {
                  mySqlConnection.Open();
                  SqlCeDataReader mySqlDataReader = mySqlCommand.ExecuteReader();
                  lbxBugged.Items.Clear();
                  while (mySqlDataReader.Read())
                  {
                      lbxBugged.Items.Add(mySqlDataReader["Bug_Code"] + mySqlDataReader["Bug_Description"] + mySqlDataReader["Bug_Author"]);
                  }
              }
              catch (SqlCeException)
              {
                  MessageBox.Show("Error populating list box");
