{
++++//+Do+Stuff
}|949161|对你来说，看起来你只需要将你的价值观串起来。MVC中的JSONValueProvider会为您将其转换回IEnumerable。|949162|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|R|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|S|8|@]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

You should be able to do this just fine:

<pre><code>$.ajax({
 url: 'controller/myaction',
 data: JSON.stringify({
 myKey: myArray
 }),
 success: function(data) { /* Whatever */ }
});
</code></pre>

Then your action method would be like so:

<pre><code>public ActionResult(List&lt;int&gt; myKey)
{
 // Do Stuff
}
</code></pre>

For you, it looks like you just need to stringify your values. The JSONValueProvider in MVC will convert that back into an IEnumerable for you.

blocks|key|949168|text|在进行get调用之前，将传统型属性设置为true。即：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|949169|jQuery.ajaxSettings.traditional+=+true

$.get('/controller/MyAction',+{+vals:+arrayOfValues+},+function+(data)+{...+|code-block|syntax|javascript|949170|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

Set the traditional property to true before making the get call.
i.e.:

<pre><code>jQuery.ajaxSettings.traditional = true

$.get('/controller/MyAction', { vals: arrayOfValues }, function (data) {... 
</code></pre>

blocks|key|949184|text|您需要将Array转换为string：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|949185|//arrayOfValues+=+[1,+2,+3];++
$.get('/controller/MyAction',+{+arrayOfValues:+"1,+2,+3"+},+function+(data)+{...|code-block|syntax|javascript|949186|这即使以int、long或string的形式也有效|949187|public+ActionResult+MyAction(int[]+arrayOfValues+)|949188|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|N|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|O|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

You need to convert Array to string :

<pre><code>//arrayOfValues = [1, 2, 3]; 
$.get('/controller/MyAction', { arrayOfValues: "1, 2, 3" }, function (data) {...
</code></pre>

this works even in form of int, long or string

<pre><code>public ActionResult MyAction(int[] arrayOfValues )
</code></pre>

blocks|key|733229|text|如果你像我一样从ASP.NET框架MVC迁移到.Net核心MVC，事情会有一些小的变化。ajax调用必须在原始对象上使用stringify，所以它应该是JSON.stringify(arrayOfValues)，而不是传递{+vals:+arrayOfValues+}的数据：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|733230|$.ajax({
+++url:+'controller/myaction',
+++data:+JSON.stringify(arrayOfValues),
+++success:+function(data)+{+/*+Whatever+*/+}
});|code-block|syntax|javascript|733231|在MVC中所做的另一个更改是为了防止跨站点请求伪造，因此对于从ASP.NET方法对method的调用，必须将[FromBody]属性应用于操作参数，如下所示：|733232|public+ActionResult+MyAction([FromBody]+IEnumerable<int>+arrayOfValues+)|733233|entityMap^0|24|T|33|N|0|0|1I|A|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@$9|R|A|S|B|C]|$9|T|A|U|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|V|8|@]|D|@]|E|$I|J]]|$1|K|3|L|5|6|7|W|8|@$9|X|A|Y|B|C]]|D|@]|E|$]]|$1|M|3|N|5|H|7|Z|8|@]|D|@]|E|$I|J]]|$1|O|3|-4|5|6|7|10|8|@]|D|@]|E|$]]]|P|$]]

If you are migrating to ASP.NET Core MVC from .Net Framework MVC like I was, things have changed slightly. The ajax call must be on the raw object using stringify so rather than passing data of <code>{ vals: arrayOfValues }</code> it should be <code>JSON.stringify(arrayOfValues)</code> as follows:

<pre><code>$.ajax({
 url: 'controller/myaction',
 data: JSON.stringify(arrayOfValues),
 success: function(data) { /* Whatever */ }
});
</code></pre>

The other change that has been made in ASP.NET Core is to prevent cross-site request forgery so for calls to an MVC action from an ajax method the <code>[FromBody]</code> atribute must be applied to the action parameter as follows:

<pre><code>public ActionResult MyAction([FromBody] IEnumerable&lt;int&gt; arrayOfValues )
</code></pre>

blocks|key|733284|text|这里有点晚了，但我可以在$.ajax()中进一步使用SNag的解决方案。以下是代码，如果对任何人有帮助的话：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|733285|var+array+=+[1,+2,+3,+4,+5];

$.ajax({
++++type:+"GET",
++++url:+'/controller/MyAction',
++++data:+$.param({+data:+array},+true),
++++contentType:+'application/json;+charset=utf-8',
++++success:+function+(data)+{
++++},
++++error:+function+(x,+y,+z)+{
++++}
});

//+Action+Method
public+void+MyAction(List<int>+data)
{
++++//+do+stuff+here
}|code-block|syntax|javascript|733286|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

A bit late here, but I could use SNag's solution further into $.ajax(). Here is the code if it would help anyone:

<pre><code>var array = [1, 2, 3, 4, 5];

$.ajax({
 type: "GET",
 url: '/controller/MyAction',
 data: $.param({ data: array}, true),
 contentType: 'application/json; charset=utf-8',
 success: function (data) {
 },
 error: function (x, y, z) {
 }
});

// Action Method
public void MyAction(List&lt;int&gt; data)
{
 // do stuff here
}
</code></pre>

blocks|key|733344|text|如果你需要在par1中传递更多的参数，JSON必须包含每个参数，我使用了以下代码：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|733345|$.ajax({
type:+"POST",
url:+URL,++++++++++++++++++++
data:+JSON.stringify({+par1:+val1,+par2:+val2+}),

dataType:+"json",

});|code-block|syntax|javascript|733346|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

If you need to pass more parameters where par1 it's an array, the JSON must contain every parameter, I used this code:
<pre><code>$.ajax({
type: &quot;POST&quot;,
url: URL, 
data: JSON.stringify({ par1: val1, par2: val2 }),
contentType: &quot;application/json; charset=utf-8&quot;,
dataType: &quot;json&quot;,
success: function (data) {},
error: function (result) {}
});
</code></pre>

I'm trying to pass an array (or IEnumerable) of ints from via AJAX to an MVC action and I need a little help. 

the javascript is 

<pre><code>$.get('/controller/MyAction', { vals: arrayOfValues }, function (data) {...
</code></pre>

and the controller action is 

<pre><code>public ActionResult MyAction(IEnumerable&lt;int&gt; arrayOfValues )
</code></pre>

At the moment the request is formatted as 

<pre><code>controller/MyAction?_=1301503418429&amp;arrayOfValues[]=491&amp;arrayOfValues[]=368&amp;arrayOfValues[]=235&amp;arrayOfValues[]=437
</code></pre>

So I'm almost there, if I take the square brackets off I get the correct response. How should I be passing that array into my get so that the controller can recognise what it is? 

Many thanks for your help
