问题描述

亲爱的先生，

如何通过使用计时器在c＃windows应用程序中逐个显示多个问题。

Dear Sir,
How to show multiple questions display in one by one in c# windows application by using timer.

推荐答案

您好，

尝试这个而不是消息你可以显示你的问题：

Hi,
try this instead of message u can show ur question :

using System.Threading;

// Somewhere in your Form, for example in Form_Load event:
new Thread(new ThreadStart(delegate {
    var d = new setLabelTextDelegate(setLabelText);
    label1.Invoke(d, new object[] { "string 1" });
    Thread.Sleep(3000); // sleep 3 seconds
    label1.Invoke(d, new object[] { "string 2" });
    Thread.Sleep(5000); // sleep 5 seconds
    label1.Invoke(d, new object[] { "string 3" });
})).Start();

private delegate void setLabelTextDelegate(string text);
private void setLabelText(string text)
{
    this.label1.Text = text;
}

这是简单的逻辑。

从哪里得到如果它来自DB然后返回行号也是1,2,3之类的那样。

声明全局变量作为needTODisplay = 1;

在计时器中检查needToDisplay with the Row Number并显示第一个问题并增加needtoDisplay。继续增加直到最后一个Question.If LastQuestion Found set needTODisplay = 1;

Hi,
Here is simple Logic.
From where you get the Questions.if its from DB then return Row Number also ex 1,2,3 like that.
Declare a Global Variable as needTODisplay=1;
In timer check the needToDisplay with the Row Number and display the 1st Question and increment needtoDisplay .Continue increment till the last Question.If LastQuestion Found set the needTODisplay=1;

更喜欢将计时器间隔设置为理想时间您想要显示每个问题。

然后在Timer_Tick中您必须添加用于连接Q源列表的代码。

Prefer you setting the timer interval to ideal time which you want each question be shown.
then in Timer_Tick you must add codes for connecting to list of your Q source.
