将数组值从一个click事件转移到另一个click事件 [英] transfer the array values from one click event to another

问题描述

需要将数组值从一个click事件转移到另一个click事件.
怎么可能?

我已经尝试过ViewState，但是它仅用于传输单个值而不是数组.
:(
这是我的代码:

Need to transfer the array values from one click event to another.
How is it possible?

I have tried ViewState but it is useful only for transfering single value not array.
:(
Here is my Code:

String[] Id_To = new String[10];
 protected void CheckButton_Click(object sender, EventArgs e)
    {
        foreach (ListItem item in CheckBoxList1.Items)
        {
            if (item.Selected)
            {
                i++;
                Id_To[i] += item.Value.ToString();
            }
        }
    }

我需要将Id_To中存储的内容传输到SendButton_Click的另一个click事件中.

I need to transfer the content stored in Id_To into another click event of SendButton_Click.

protected void SendButton_Click(object sender, EventArgs e)
    {
      
    }

How is it possible?

推荐答案

检查示例..

Check the sample..

protected void Page_Load(object sender, EventArgs e)
{
 String[] myArray = { "1", "4", "5", "6", "7" };
 Session["arr"] = myArray;
}
protected void SendButton_Click(object sender, EventArgs e)
{
//you will have the myarray values in test.
String[] test = (String[])Session["arr"];
}

如果您想在CheckButton_Click事件中的会话中使用数组而不发生此事件，则从您的代码开始，如果您单击SendButton，则该会话将为空.

From your code as you want to use the array in session in CheckButton_Click event without happening of this event if you click on SendButton the session will be null.

存储该数组值在session ["Array"]

在其他情况下使用它，然后

清除该会话

store that array value in session["Array"]

use that in other event and then

clear that session
