This takes just a tiny bit of reflection to accomplish.

<pre><code>var a = new { data1 = "test1", data2 = "sam", data3 = "bob" };
var type = a.GetType();
var props = type.GetProperties();
var pairs = props.Select(x =&gt; x.Name + "=" + x.GetValue(a, null)).ToArray();
var result = string.Join("&amp;", pairs);

blocks|key|956521|text|如果您使用的是.NET+3.5+SP1或.NET+4，您可以(Ab)使用RouteValueDictionary来完成此任务。它实现了IDictionary<string,+object>，并有一个接受object并将属性转换为键值对的构造函数。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|956522|然后，循环遍历键和值以构建查询字符串将变得非常简单。|956523|entityMap|0|LINK|mutability|MUTABLE|url|http://msdn.microsoft.com/en-us/library/system.web.routing.routevaluedictionary.aspx^0|10|K|1V|R|2T|6|10|K|0|0|0^^$0|@$1|2|3|4|5|6|7|P|8|@$9|Q|A|R|B|C]|$9|S|A|T|B|C]|$9|U|A|V|B|C]]|D|@$9|W|A|X|1|Y]]|E|$]]|$1|F|3|G|5|6|7|Z|8|@]|D|@]|E|$]]|$1|H|3|-4|5|6|7|10|8|@]|D|@]|E|$]]]|I|$J|$5|K|L|M|E|$N|O]]]]

If you are using .NET 3.5 SP1 or .NET 4, you can (ab)use <a href="http://msdn.microsoft.com/en-us/library/system.web.routing.routevaluedictionary.aspx" rel="noreferrer"><code>RouteValueDictionary</code></a> for this. It implements <code>IDictionary&lt;string, object&gt;</code> and has a constructor that accepts <code>object</code> and converts properties to key-value pairs.

It would then be trivial to loop through the keys and values to build your query string.

Here is how they do it in RouteValueDictionary:

<pre><code> private void AddValues(object values)
 {
 if (values != null)
 {
 foreach (PropertyDescriptor descriptor in TypeDescriptor.GetProperties(values))
 {
 object obj2 = descriptor.GetValue(values);
 this.Add(descriptor.Name, obj2);

@kbrimington's solution makes a nice extension method - my my case returning a HtmlString

<pre><code> public static System.Web.HtmlString ToHTMLAttributeString(this Object attributes)
 {
 var props = attributes.GetType().GetProperties();
 var pairs = props.Select(x =&gt; string.Format(@"{0}=""{1}""",x.Name,x.GetValue(attributes, null))).ToArray();
 return new HtmlString(string.Join(" ", pairs));
 }
</code></pre>

I'm using it to drop arbitrary attributes into a Razor MVC view. I started with code using RouteValueDictionary and looping on the results but this is much neater.

There is a built-in method of converting anonymous objects to dictionaries:

blocks|key|1171089|text|虽然为时已晚，但不管怎样，我还是会将其添加到一个更健壮的解决方案中。我在这里看到的这些工具都有一些问题(比如它们在DateTime上就不能正常工作)。因此，我建议首先转换为json+(Newtonsoft+Json.Net)：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1171090|var+data+=+new+{data1+=+"test1",+data2+=+"sam",+data3+=+"bob"};

var+result+=+string.Join("&",

It is too late but anyway I would add this for a more robust solution. The ones I see here have some kind of problems (like they wouldn't work right with say DateTime). For that reason, I suggest first converting to a json (Newtonsoft Json.Net):
<pre><code>var data = new {data1 = &quot;test1&quot;, data2 = &quot;sam&quot;, data3 = &quot;bob&quot;};

var result = string.Join(&quot;&amp;&quot;,
 JsonConvert.DeserializeObject&lt;Dictionary&lt;string, string&gt;&gt;(
 JsonConvert.SerializeObject(data))
 .Select(x =&gt; $&quot;{x.Key}={x.Value}&quot;)
 );
</code></pre>

I have the following anonymous type:

<pre><code>new {data1 = "test1", data2 = "sam", data3 = "bob"}
</code></pre>

I need a method that will take this in, and output key value pairs in an array or dictionary. 

My goal is to use this as post data in an HttpRequest so i will eventually concatenate in into the following string:

<pre><code>"data1=test1&amp;data2=sam&amp;data3=bob"
</code></pre>

In c# convert anonymous type into key/value array?
