推荐答案

正如ThePhantomUpvoter所说，你应该尝试使用JavaScript，而不是使用C＃。

试试这个：

Hi,

As ThePhantomUpvoter said, you should try to do this with JavaScript, not with C#.
Try this:

<form runat="server">
    <asp:TextBox runat="server" BackColor="Red" ID="textbox1" />
    <asp:TextBox runat="server" BackColor="Green" ID="textbox2" />
    <asp:textbox runat="server" BackColor="Blue" ID="textbox3" />
</form>
<script type="text/javascript">
    var txtbox1 = document.getElementById("<%=textbox1.ClientID%>");
    var txtbox2 = document.getElementById("<%=textbox2.ClientID%>");
    var txtbox3 = document.getElementById("<%=textbox3.ClientID%>");
    setInterval(function () {
        prevColorTxt1 = txtbox1.style.backgroundColor;
        prevColorTxt2 = txtbox2.style.backgroundColor;
        prevColorTxt3 = txtbox3.style.backgroundColor;
        txtbox2.style.backgroundColor = prevColorTxt1;
        txtbox3.style.backgroundColor = prevColorTxt2;
        txtbox1.style.backgroundColor = prevColorTxt3;
    }, 5000, null);
</script>

Hope this helps.

static int flag = 0;
    static int counter = 1;
    protected void Page_Load(object sender, EventArgs e)
    {
        if (flag == 0)
        {
            TextBox1.BackColor = System.Drawing.Color.Red;
            TextBox2.BackColor = System.Drawing.Color.Green;
            TextBox3.BackColor = System.Drawing.Color.Blue;

            flag = 1;
            counter = 1;
        }
    }
    protected void Timer1_Tick(object sender, EventArgs e)
    {
        if (counter == 1)
        {
            TextBox1.BackColor = System.Drawing.Color.Blue;
            TextBox2.BackColor = System.Drawing.Color.Red;
            TextBox3.BackColor = System.Drawing.Color.Green;
            counter = 2;
        }
        else if (counter == 2)
        {
            TextBox1.BackColor = System.Drawing.Color.Green;
            TextBox2.BackColor = System.Drawing.Color.Blue;
            TextBox3.BackColor = System.Drawing.Color.Red;
            counter = 3;
        }
        else if (counter == 3)
        {
            TextBox1.BackColor = System.Drawing.Color.Red;
            TextBox2.BackColor = System.Drawing.Color.Green;
            TextBox3.BackColor = System.Drawing.Color.Blue;
            counter = 0;
            flag = 0;
        }
    }

嗨！我使用Winform来完成这个任务



private void Form1_Load（object sender，EventArgs e）

{

timer1.Interval = 5000;

timer1.Tick + = new EventHandler（timer1_Tick）;

timer1.Start（）;



}



void timer1_Tick（对象发送者，EventArgs e）

{

颜色temp1 = textBox1.BackColor;

textBox1.BackColor = textBox3.BackColor;



颜色temp2 = textBox2.BackColor;

textBox2.BackColor = temp1;



颜色temp3 = textBox3.BackColor;

textBox3.BackColor = temp2;

}

Hi! I use Winform to do this task

private void Form1_Load(object sender, EventArgs e)
{
timer1.Interval = 5000;
timer1.Tick += new EventHandler(timer1_Tick);
timer1.Start();

}

void timer1_Tick(object sender, EventArgs e)
{
Color temp1 = textBox1.BackColor;
textBox1.BackColor = textBox3.BackColor;

Color temp2 = textBox2.BackColor;
textBox2.BackColor = temp1;

Color temp3 = textBox3.BackColor;
textBox3.BackColor = temp2;
}
