Hello everyone,

I am working on a project an I have a problem with using checked list boxes. I have 5 items which were inserted in a checked listboxes and I have put in an array all the items prices.(10,20,30,40,50) accordingly. I want this;

* When user clicked item1 the actual price will be 10 $
* When user clicked item2 the actual price will be 30 $(Both 1 and 2)
* When user Re-clicked item1 the actual price will be 20 $(Just second item clicked)

and so on.

if (checkedListBoxAdditions.CheckedItems.Count != 0)
   {
   string s = "";
            for (int x = 0; x <= checkedListBoxAdditions.CheckedItems.Count - 1; x++)
     {
         if (checkedListBoxAdditions. == true)
         {
             totalAmount = totalAmount + price[4];
         }
         if (x == 2)
         {
             totalAmount = totalAmount + price[5];
         }
         if (x == 3)
         {
             totalAmount = totalAmount + price[6];
         }
         if (x == 4)
         {
             totalAmount = totalAmount + price[7];
         }
         if (x == 5)
         {
             totalAmount = totalAmount + price[8];
         }

     }
            MessageBox.Show(totalAmount + "");


   }

推荐答案

*当用户单击item2时，实际价格为30

* When user clicked item2 the actual price will be 30

(1和2均是)
*当用户重新单击item1时，实际价格为20

(Both 1 and 2)
* When user Re-clicked item1 the actual price will be 20

(仅单击第二项)

等等.

(Just second item clicked)

and so on.

if (checkedListBoxAdditions.CheckedItems.Count != 0)
   {
   string s = "";
            for (int x = 0; x <= checkedListBoxAdditions.CheckedItems.Count - 1; x++)
     {
         if (checkedListBoxAdditions. == true)
         {
             totalAmount = totalAmount + price[4];
         }
         if (x == 2)
         {
             totalAmount = totalAmount + price[5];
         }
         if (x == 3)
         {
             totalAmount = totalAmount + price[6];
         }
