You can create list of picture boxes on your user control:

<pre><code>List&lt;PictureBox&gt; boxes = new List&lt;PictureBox&gt;();
</code></pre>

Now after picture boxes initializes in constructor add them to list:

<pre><code>boxes.Add(pictureBox1);
boxes.Add(pictureBox2);
...
</code></pre>

Now make it visible byu public property:

<pre><code>public List&lt;PictureBox&gt; Boxes
{
 get 
 {
 return this.boxes;
 }
}
</code></pre>

Now you can assign in your class by:

<pre><code>Boxes[0].Image = Properties.Resources.i51;
Boxes[1].Image = Properties.Resources.i51;
</code></pre>

If all is happeining in the same class, you don't need to create above public property.

blocks|key|4978580|text|将你所有的图片框填入一个列表，比如已经提供的msmolka，并在其中添加一个ReadyOnlyCollection：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4978581|private+List<PictureBox>+_PictureBoxes;
private+ReadOnlyCollection<PictureBox>+_PictureBoxesReadOnly;|code-block|syntax|javascript|4978582|在构造函数中实例化它：|4978583|public+MyUserControl()
{
+++++InitializeComponent();
+++++_PictureBoxes+=+new+List<PictureBox>();
+++++_PictureBoxesReadOnly+=+_PictureBoxes.AsReadOnly();
}|4978584|并使ReadOnlyCollection仅作为IList可用|offset|length|style|CODE|4978585|public+IList<PictureBox>+PictureBoxes
{
++++get+{+return+_PictureBoxesReadOnly;+}
}|4978586|这(在我看来)比msmolka的方法更好。为了使它更完美，我也不会将整个PictureBoxes提供给外部世界，而是只将Images作为BindingList。但我认为对于初学者来说，你可以从上面开始，也许以后会改进这些东西。|4978587|entityMap^0|0|0|0|0|N|5|0|0|1O|5|1W|B|0^^$0|@$1|2|3|4|5|6|7|W|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|X|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Y|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|Z|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|10|8|@$M|11|N|12|O|P]]|9|@]|A|$]]|$1|Q|3|R|5|D|7|13|8|@]|9|@]|A|$E|F]]|$1|S|3|T|5|6|7|14|8|@$M|15|N|16|O|P]|$M|17|N|18|O|P]]|9|@]|A|$]]|$1|U|3|-4|5|6|7|19|8|@]|9|@]|A|$]]]|V|$]]

Fill all your picture boxes into a list like msmolka already provided and also add a ReadyOnlyCollection to it:

<pre><code>private List&lt;PictureBox&gt; _PictureBoxes;
private ReadOnlyCollection&lt;PictureBox&gt; _PictureBoxesReadOnly;
</code></pre>

Instantiate it within the constructor:

<pre><code>public MyUserControl()
{
 InitializeComponent();
 _PictureBoxes = new List&lt;PictureBox&gt;();
 _PictureBoxesReadOnly = _PictureBoxes.AsReadOnly();
}
</code></pre>

And make the ReadOnlyCollection only available as <code>IList</code>:

<pre><code>public IList&lt;PictureBox&gt; PictureBoxes
{
 get { return _PictureBoxesReadOnly; }
}
</code></pre>

This is (in my eyes) better than the approach from msmolka. For making it perfect i would also not give the whole PictureBoxes to the outer world, but instead only the <code>Image</code>s as a <code>BindingList</code>. But i think for a beginner you can start with the above and maybe improve this stuff later.

please consider that this is my first very post and that I´m a newcomer in C#

I'm creating a UserControl with several pictureBoxes. These objects are automatically named pictureBox1, pictureBox2, pictureBox3 and so on.

Now i want to change the associated image by clicking:

<pre><code>pictureBox1.Image = Properties.Resources.i51; 
</code></pre>

so far, so good. But how to assigne the number without writing a single line for each event?

<pre><code>pictureBox(1).Image = Properties.Resources.i51;
</code></pre>

doesn´t work, and lots of others don´t too.

any hint? Many thanks in advance!
