Okay, I think I figured it out. I did it like this.

<pre><code>while (true)
 {
 if (x &lt; 750 &amp;&amp; y == 0)
 {
 x += 5;
 }
 else if (x == 750 &amp;&amp; y &lt; 340)
 {
 y += 5;
 }
 else if (x &gt; 0 &amp;&amp; y &gt;= 340)
 {
 x -= 5;
 }
 else if (x == 0 &amp;&amp; y &gt; 0)
 {
 y -= 5;
 }
 break;
 }
</code></pre>

But I have a feeling that there is a more simple and elegant way to do this. Can anyone suggest something better?

Since I do not know where you want to go from there, I will provide you with the most staight forward solution:

<pre><code>if (y &lt;= 0 &amp;&amp; x &lt; 750)
{
 x += 5;
}
else if (x == 750 &amp;&amp; y &lt; 340)
{
 y += 5;
}
else if (y &gt;= 340 &amp;&amp; x &gt; 0)
{
 x-=5;
}
else if (y &gt; 0 &amp;&amp; x &lt;= 0)
{
 y-=5;
}
break;
</code></pre>

You may have to tweak the values a bit, but I guess you can figure it out from here.

blocks|key|35855|text|你不需要while循环，因为你正在使用计时器，也不要检查if语句中的常量值，因为如果你改变表单大小，这些值将不起作用。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|35856|使用以下代码：|35857|private+void+movingTimer_Tick(object+sender,+EventArgs+e)
{
++++if+(y+<=+0+&&+x+<+this.ClientSize.Width-20)
++++{
++++++++x+%2B=+5;
++++++++y+=+0;
++++}
++++if+(x+>=+this.ClientSize.Width+-+20+&&+y<+this.ClientSize.Height-20)
++++{
++++++++x+=+this.ClientSize.Width+-+20;
++++++++y+%2B=+5;
++++}
++++if(y>=+this.ClientSize.Height+-20)
++++{
++++++++x+-=+5;
++++++++y+=+this.ClientSize.Height+-+20;
++++}
++++if+(x+<=0+&&+y+>0)
++++{
++++++++x+=+0;
++++++++y+-=+5;

++++Invalidate();

You dont need a while loop since you are using a timer, also do not check constant values in your if statements as these values will not work if you change the form size.

Use the following code:

<pre><code>private void movingTimer_Tick(object sender, EventArgs e)
{
 if (y &lt;= 0 &amp;&amp; x &lt; this.ClientSize.Width-20)
 {
 x += 5;
 y = 0;
 }
 if (x &gt;= this.ClientSize.Width - 20 &amp;&amp; y&lt; this.ClientSize.Height-20)
 {
 x = this.ClientSize.Width - 20;
 y += 5;
 }
 if(y&gt;= this.ClientSize.Height -20)
 {
 x -= 5;
 y = this.ClientSize.Height - 20;
 }
 if (x &lt;=0 &amp;&amp; y &gt;0)
 {
 x = 0;
 y -= 5;
 }

 Invalidate();
}
</code></pre>

I'm trying to make a Windows Forms Application where rectangle moves clockwise. Here's the image.
<a href="https://i.stack.imgur.com/4b0Lb.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/4b0Lb.png" alt="enter image description here"></a>

And here is my code.

<pre><code>public partial class Form1 : Form
{
 int x;
 int y;

 public Form1()
 {
 InitializeComponent();
 }

 private void Form1_Paint(object sender, PaintEventArgs e)
 {
 e.Graphics.FillRectangle(Brushes.Crimson, x, y, 20, 20);
 }

 private void movingTimer_Tick(object sender, EventArgs e)
 {
 while (true)
 {
 if (x &lt; 750)
 {
 x += 5;
 }
 else if (x == 750 &amp;&amp; y &lt; 340)
 {
 y += 5;
 }
 break;
 }

 Invalidate();
 }
}
</code></pre>

I understand why I can't go further. If I make new if statement with x -= 5 it will be activated simultaneously with the while loop. 
What I can't understand is how to separate the new commands (x -= 5 and y -= 5) so it would be activated only after my first while loop is finished.
