blocks|key|880833|text|嗯，在C#中是类似的。下面是一个最简单的例子(仅适用于公共属性)：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|880834|var+someObject+=+new+{+.../*properties*/...+};
var+propertyInfos+=+someObject.GetType().GetProperties();
foreach+(PropertyInfo+pInfo+in+propertyInfos)
{
++++string+propertyName+=+pInfo.Name;+//gets+the+name+of+the+property
++++doSomething(pInfo.GetValue(someObject,null));
}|code-block|syntax|javascript|880835|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|$]]

well, in C# it's similar.
Here's one of the simplest examples (only for public properties):
<pre><code>var someObject = new { .../*properties*/... };
var propertyInfos = someObject.GetType().GetProperties();
foreach (PropertyInfo pInfo in propertyInfos)
{
 string propertyName = pInfo.Name; //gets the name of the property
 doSomething(pInfo.GetValue(someObject,null));
}
</code></pre>

blocks|key|1095661|text|这应该可以做到：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1095662|Type+myType+=+myObject.GetType();
IList<PropertyInfo>+props+=+new+List<PropertyInfo>(myType.GetProperties());

foreach+(PropertyInfo+prop+in+props)
{
++++object+propValue+=+prop.GetValue(myObject,+null);

++++//+Do+something+with+propValue

This should do it:

<pre><code>Type myType = myObject.GetType();
IList&lt;PropertyInfo&gt; props = new List&lt;PropertyInfo&gt;(myType.GetProperties());

foreach (PropertyInfo prop in props)
{
 object propValue = prop.GetValue(myObject, null);

 // Do something with propValue
}
</code></pre>

From the world of PHP I have decided to give C# a go. I've had a search but can't seem to find the answer of how to do the equivalent to this.

<pre><code>$object = new Object();

$vars = get_class_vars(get_class($object));

foreach($vars as $var)
{
 doSomething($object-&gt;$var);
}
</code></pre>

I basically have a List of an object. The object could be one of three different types and will have a set of public properties. I want to be able to get a list of the properties for the object, loop over them and then write them out to a file.
I'm thinking this has something to do with c# reflection but it's all new to me.

Any help would be greatly appreciated.
