title: C# Loop checkbox and add value
body: <p>I'm trying to add values of phones numbers based on checkbox's in the UI.
  For example if a checkbox1 (which represent phone1) is checked and checkbox2 is also checked then the program will add both phones' values. 
  How can I add the value (in for loop for example) so that the if statement is lesser and simplified.</p>
  
  <p>Here is my code:</p>
  
  <pre><code>public double totalPhone()
      {
          double total = 0;
          double item1 = 2249;
          double item2 = 1769;
          double item3 = 3099;
          double item4 = 1198;
          double item5 = 1899;
  
          if (chkPhone1.Checked == true)
          {
              total = total + item1;
          }
  
          if (chkPhone2.Checked == true)
          {
              total = total + item2;
          }
  
          if (chkPhone3.Checked == true)
          {
              total = total + item3;
          }
  
          if (chkPhone4.Checked == true)
          {
              total = total + item4;
          }
  
          if (chkPhone5.Checked == true)
          {
              total = total + item5;
          }
  
          return total;
      }
  </code></pre>
