Dynamically create javascript array with c# code behind
提问by flavour404
I am updating an old classic ASP site to a new .net 3.5 version. The page has a custom list control which the client (my boss) wants to keep. This list control requires several arrays in order to work correctly. the array is a multi-dimensional list of publications. This is what it looks like:
我正在将旧的经典 ASP 站点更新为新的 .net 3.5 版本。该页面有一个客户（我的老板）想要保留的自定义列表控件。此列表控件需要多个数组才能正常工作。该数组是一个多维出版物列表。这是它的样子：
var publicationTable = [
[31422,"Abilene Reporter News","Abilene","TX",false,"D",0],
[313844,"Acadiana Weekly","Opelousas","LA",false,"W",1],
[527825,"Action Advertiser","Fond du Lac","WI",false,"W",2]...n]
I want to generate this array server side and register it. I have looked at the msdnbut this is a little trivial. The conceptual issue is that the array is a mixture of string and ints and I am not sure how to recreate this, so how?
我想生成这个数组服务器端并注册它。我看过msdn但这有点微不足道。概念上的问题是数组是字符串和整数的混合体，我不确定如何重新创建它，那么如何呢？

You should do this:
你应该做这个：
Code behind:
后面的代码：
using System.Web.Script.Serialization;
...
public string getJson(){
var publicationTable = new List<object>{
new []{ 31422,"Abilene Reporter News","Abilene","TX",false,"D",0},
new []{ 313844,"Acadiana Weekly","Opelousas","LA",false,"W",1 },
new []{ 527825,"Action Advertiser","Fond du Lac","WI",false,"W",2}
};
return (new JavaScriptSerializer()).Serialize(publicationTable);
}
Ase you see, to create an array of mixed types, we create an array of anonymous type with new []. You could also have done it with new object[].
如您所见，要创建混合类型的数组，我们使用new []. 你也可以用new object[].
Aspx file:
Aspx文件：
<script>
var publicationTable = <%= getJson() %>;
</script>
Hope this helps. Cheers
希望这可以帮助。干杯

I think a List<List<object>>containing your items, passed through the JavaScriptSerializerwould do the trick. Given that this data probably comes from a more structured data type, you could probably do better than List<List<object>>, but the JavaScriptSerializeris probably what you're after.
我认为一个List<List<object>>包含你的物品，通过JavaScriptSerializer就可以了。鉴于此数据可能来自更结构化的数据类型，您可能会比 做得更好List<List<object>>，但这JavaScriptSerializer可能就是您所追求的。

Will this work?
这会奏效吗？
ArrayList list = new ArrayList{31422,"Abilene Reporter News","Abilene","TX",false,"D",0};
var str = string.Format("[{0}]", list.Cast<object>().Select(x => (x is string)?
string.Format(@"""{0}""", x) : x.ToString())
.Aggregate((x, y) => string.Format("{0}, {1}", x, y)));
it can be extended for a multi-dimensional array in a similar fashion.
它可以以类似的方式扩展到多维数组。
