Question

我对C＃中的数组列表有疑问

我有一个包含以下元素的数组：

- LQI Request
- 0123456
- LQI Request
- 456789
- LQI Request
- 6789
.....

现在我想做的就是找到LQI Request的字符串，然后在它旁边找到字符串，这是我迄今为止所做的:(索引是全局的变量）

if(myString.Contains("LQI"))
            {
                index= stored_data.IndexOf(myString);
            }
MessageBox.Show(index.ToString());
MessageBox.Show(stored_data[index+1].Tostring());

我运行此代码的时候，索引保持不变。它应该是：0,2,4

请帮忙

Answer 1

下面的内容就是你所描述的。

static void Main(string[] args)
    {

        List<String> stored_data = new List<String>() { "LQI REquest","-0123456", "LQI Request", "-456789", "LQI Request", "-6789", "non valid", "12345", "extra", "12354" };
        for (int j=0; j< stored_data.Count; j++)
        {

            if (stored_data[j].Contains("LQI"))
            {

                Console.Write((j).ToString()+ ": ");
                var temp = j + 1;
                Console.Write(stored_data[temp]);
                Console.WriteLine();
            }

        }

        Console.ReadLine();
    }

<div class="panel-body">
    <div class="col-md-2" id="Active" onclick="activeCircleClick('tab1')">
        <div id="active" style="height: 125px;">
            //here is something
        </div>
    </div>
</div>

<div style="width:1300px;">
    <div style="width:100%;">
        <ul class="nav nav-tabs nav-pills nav-justified" role="tablist" id="myTab">
            <li class="active" id="activeList">
                <a href="#tab1" data-toggle="tab">Active device list</a>
                <span class="col-md-12" id="activeDeviceStatus" style="text-align: center;"></span>
            </li>           
        </ul>
    </div>

<script>
    function activeCircleClick(el)
    {
        alert("test1:" +el);
        selectTab(el);  
    }
    function selectTab(tabId)
    {
        alert('test2:' + tabId);
        var tab = $("#" + tabId);
        if (typeof tab != 'undefined')
        {
            e.preventDefault()
            tab.tab('show');
        }
    }

</script>
