如何将整数值从一个控制块传递给另一个控制块？ [英] How to pass integer value form one block of control to another ?

问题描述

您好，我做了一个在块中有整数值的代码。我已将此值传递给按钮单击事件上的另一个块，但我想将相同的整数值传递给第3个块。我做了这段代码：

  void  wc_DownloadStringCompleted1（ object  sender，DownloadStringCompletedEventArgs e）
 {
 ... 
  dynamic  num = label1 .Bottom +（i *  30 ）; 
 button1.Click + =  new  EventHandler（（sender1，e1）= >  button1_Click（发件人，e，num）; 
} 

我已将此整数值传递给以下代码：

  void  browsebutton_Click（ object  sender，DownloadStringCompletedEventArgs e，< span class =code-keyword> int  num）
 {
 ... 
 wc.DownloadStringCompleted + = wc_DownloadStringCompleted2; 
  //   [取而代之的我也尝试了这个：wc.DownloadStringCompleted + = new // DownloadStringCompletedEventHandler（（sndr，ev）=> wc_DownloadStringCompleted2（发件人， e，// num））;但是当我使用它时控件不会进入第3块]  
} 

现在我想要将该num值传递给下一个块

  void  wc_DownloadStringCompletedbrowse2（ object  sender，DownloadStringCompletedEventArgs e）
 {
 .... 
} 

请任何人给我任何建议。



谢谢。

解决方案

将 num 更改为类的成员变量，可以从该类的所有函数/属性访问它

Hello, I did a code which have an integer value in a block. I have passed this value to another block on button click event but I want to pass the same integer value to the 3rd block. I did this code :

void wc_DownloadStringCompleted1(object sender, DownloadStringCompletedEventArgs e)
{
    ...
    dynamic num = label1.Bottom + (i * 30);
    button1.Click += new EventHandler((sender1, e1) => button1_Click(sender, e, num);
}

I have passed this integer value to the following code :

void browsebutton_Click(object sender, DownloadStringCompletedEventArgs e, int num)
{
    ...
    wc.DownloadStringCompleted += wc_DownloadStringCompleted2;
//[In its place I also tried this : wc.DownloadStringCompleted +=new     //DownloadStringCompletedEventHandler((sndr, ev) => wc_DownloadStringCompleted2(sender, e, //num)); but when I used this the control is not going to the 3rd block]
}

Now I want to pass that num value to the following block

void wc_DownloadStringCompletedbrowse2(object sender, DownloadStringCompletedEventArgs e)
{
   ....
}

Please any one give me any suggestion.

Thanks.

解决方案

Change num into a member variable of the class, it will be accessible from all functions/properties of that class then.
