获取CheckBoxList项目值 [英] Getting CheckBoxList Item values

问题描述

我有一个CheckBoxList，其中装有数据.当我尝试从列表中检索选中的项目时，我只能按顺序抓取该项目，而无法获取该值.

I have a CheckBoxList which I'm populating with data. When I attempt to retrieve the checked items from the list I can only grab the item ordinal, I cannot get the value.

我已经读到您可以使用Items [i] .Value，但是当我尝试执行此操作时，我收到一条错误消息，指出没有扩展方法'value'.

I've read that you can use Items[i].Value however when I try to do this I get an error stating that there is no extension method 'value'.

这是我用来尝试获取信息的代码(请注意，GetItemText(i)实际上只给了我项目的位置，而不是项目的文本)

Here's the code I'm using to try and grab the information (note the GetItemText(i) actually only gives me the item position, not the text for the item)

   private void btnGO_Click(object sender, EventArgs e)
{
    for (int i = 0; i < chBoxListTables.Items.Count; i++)
    {
        if (chBoxListTables.GetItemChecked(i))
        {
            string str = chBoxListTables.GetItemText(i);
            MessageBox.Show(str);

            //next line invalid extension method
            chBoxListTables.Items[i].value;
        }
    }
}

这是使用.Net 4.0

This is using .Net 4.0

任何想法都会受到赞赏...谢谢

Any thoughts would be appreciated...thanks

推荐答案

这最终变得非常简单.chBoxListTables.Item [i]是一个字符串值，并且通过显式转换将其加载到变量中.以下代码有效:

This ended up being quite simple. chBoxListTables.Item[i] is a string value, and an explicit convert allowed it to be loaded into a variable. The following code works:

private void btnGO_Click(object sender, EventArgs e)
{
    for (int i = 0; i < chBoxListTables.Items.Count; i++)
    {
          if (chBoxListTables.GetItemChecked(i))
        {
            string str = (string)chBoxListTables.Items[i];
            MessageBox.Show(str);
        }
    }
}
