All you can do is to loop through all controls and then check if its CssClassis something
您所能做的就是遍历所有控件，然后检查它CssClass是否是something
i.e. if that div is inside a the div with ID Div1then you will use:
即，如果该 div 位于带有 ID 的 div 内，Div1那么您将使用：
foreach (Control c in Div1.Controls)
{
if (c.CssClass == "something")
{
// do the moves here
}
}

Make it a server tag if you want to access it in CS code.
如果您想在 CS 代码中访问它，请将其设为服务器标记。
<div class="something" runat="server" id="something">
//somecode
<div>
asp.net does not provide a method to search by classes. so you will have to rely on the ID.
asp.net 不提供按类搜索的方法。所以你将不得不依赖ID。
CS:
CS：
something.InnerHtml = "some code";

You need the runat='server' attribute and ID.
您需要 runat='server' 属性和 ID。
<div class="something" runat="server" id="TestDiv">
//somecode
<div>
Then in code behind:
然后在后面的代码中：
protected void Page_Load(object sender, EventArgs e)
{
TestDiv.InnerHtml += "test"; // The div is accessible
}

Another solution that may help solve some of the issues encountered by others in the comments of the selected answer would be to use the Control class with the FindControl() method to access the desired element.
另一种可能有助于解决其他人在所选答案的评论中遇到的一些问题的解决方案是使用具有 FindControl() 方法的 Control 类来访问所需的元素。
For example:
例如：
Control myDiv = (Control)FindControl("myDiv");
myDiv.Visible = false;
I found this to be quite effective, hopefully it can help someone else out.
我发现这非常有效，希望它可以帮助其他人。
