You dont create confirm box in a Controller, but yes in a View, using JQuery Dialog. The Controller is already inside the server, so you don't have user interactions there. Your View, in the other hand, is the place where the user will choose options, type information, click on buttons etc... You can intercept the button click, to show that dialog, and only submit the post when the option "Yes" gets clicked.
您不在控制器中创建确认框，但在视图中创建确认框，使用 JQuery 对话框。控制器已经在服务器内部，因此您在那里没有用户交互。另一方面，您的视图是用户选择选项、键入信息、单击按钮等的地方……您可以拦截按钮单击以显示该对话框，并且仅在选项“是”时提交帖子"被点击。
JQuery Dialog requires jquery.js, jquery-ui.js, jquery.ui.dialog.jsscripts referenced in your page.
JQuery Dialog 需要页面中引用的jquery.js、jquery-ui.js、jquery.ui.dialog.js脚本。
Example:
例子：
$(function(){
$("#buttonID").click(function(event) {
event.preventDefault();
$('<div title="Confirm Box"></div>').dialog({
open: function (event, ui) {
$(this).html("Yes or No question?");
},
close: function () {
$(this).remove();
},
resizable: false,
height: 140,
modal: true,
buttons: {
'Yes': function () {
$(this).dialog('close');
$.post('url/theValueYouWantToPass');
},
'No': function () {
$(this).dialog('close');
$.post('url/theOtherValueYouWantToPAss');
}
}
});
});
});

You can do this with ActionLink
你可以用 ActionLink 做到这一点
@Html.ActionLink(
"Delete",
"DeleteAction",
"Product",
new { confirm = true, other_parameter = "some_more_parameter" },
new { onclick = "return confirm('Do you really want to delete this product?')" })
If user confirm, then link parameter will pass to the controller action method.
如果用户确认，则链接参数将传递给控制器操作方法。
public ActionResult DeleteAction(bool confirm, string other_parameter)
{
// if user confirm to delete then this action will fire
// and you can pass true value. If not, then it is already not confirmed.
return View();
}

You can not show message box in controller side. But you can do this like following
您不能在控制器端显示消息框。但是你可以像下面这样做
public ActionResult ActionName(passing value)
{
// some code
message box here
if (true){ ViewBag.Status = true }
else { ViewBag.Status = false}
return View();
}
And view
并查看
<script type="text/javascript">
function() {
var status = '@ViewBag.Status';
if (status) {
alert("success");
} else {
alert("error");
}
}
</script>
But these all codes are not elegant way. This is solution of your scenerio.
但是这些所有代码都不是优雅的方式。这是您的场景的解决方案。

Yes, you can do this with @Html.ActionLinkas AliR?za Ad?yah?i has commented.
是的，你可以@Html.ActionLink像 AliR?za Ad?yah?i 评论的那样做到这一点。
Subscribe to the onclickevent of the @Html.ActionLink
订阅onclick事件@Html.ActionLink
Here is the implementation:
这是实现：
@Html.ActionLink("Click here","ActionName","ControllerName",new { @onclick="return Submit();"})
And in javascript write the confirmbox.
并在 javascript 中编写该confirm框。
<script type="text/javascript">
function Submit() {
if (confirm("Are you sure you want to submit ?")) {
return true;
} else {
return false;
}
}
</script>
Edit

Try like this:
像这样尝试：
<script type="text/javascript">
function Submit() {
if (confirm("Are you sure you want to submit ?")) {
document.getElementById('anchortag').href += "?isTrue=true";
} else {
document.getElementById('anchortag').href += "?isTrue=false";
}
return true;
}
</script>
@Html.ActionLink("Submit", "Somemethod", "Home", new { @onclick = "return Submit();", id = "anchortag" })
Now in your controller do some operations based on the isTruequerystring
现在在您的控制器中根据isTrue查询字符串执行一些操作
public ActionResult Somemethod(bool isTrue)
{
if (isTrue)
{
//do something
}
else
{
//do something
}
return View();
}

I can confirm that AliR?za Ad?yah?i's solution works well.
我可以确认 AliR?za Ad?yah?i 的解决方案运行良好。
You can also customize the the message. In my case we're using MVC and Razor, so I could do this:
您还可以自定义消息。就我而言，我们使用的是 MVC 和 Razor，所以我可以这样做：
<td>
@Html.ActionLink("Delete",
"DeleteTag", new { id = t.IDTag },
new { onclick = "return confirm('Do you really want to delete the tag " + @t.Tag + "?')" })
</td>
Which showed a dialog with a specific record named in it. Might also be possible to give the confirm dialog a title, haven't tried that yet.
其中显示了一个对话框，其中包含一个特定的记录。也可以给确认对话框一个标题，还没试过。

<a href="@Url.Action("DeleteBlog", new {id = @post.PostId})" class="btn btn-sm btn-danger" onclick="return confirm ('Are you sure want to delete blog?');">
<i class="glyphicon glyphicon-remove"></i> Delete
