blocks|key|5421031|text|我相信这应该行得通。正如您建议的那样，只使用泛型即可。为了在你的方法中获得它，你只需在任何地方改变变量类型(它不一定是T，但这是惯例)。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5421032|internal+static+void+AssignNewArrayItem<T>(ref+T[]+Items,+T+Item)
{

++++++++Items[Items.Length+-+1]+=+Item;
++++}
++++else
++++++++Items+=+new+T+{+Item+};
}|code-block|syntax|javascript|5421033|不过，您可能应该将constraints放在该方法上。你有你想要的基类型吗？如果是这样，您可以这样做：|offset|length|5421034|internal+static+void+AssignNewArrayItem<T>(ref+T[]+Items,+T+Item)+

I believe this should work. As you suggested yourself, just use generics. To get this in your method, you simply change anywhere there is going to be a variable type with the value between the brackets (it does not have to be T, but that is the convention)

<pre><code>internal static void AssignNewArrayItem&lt;T&gt;(ref T[] Items, T Item)
{
 if (Items != null)
 {
 Array.Resize(ref Items, Items.Length + 1);
 Items[Items.Length - 1] = Item;
 }
 else
 Items = new T { Item };
}
</code></pre>

You should possibly put <a href="http://msdn.microsoft.com/en-us/library/d5x73970.aspx" rel="nofollow">constraints</a> on the method, though. Do you have a base type you are expecting? If so, you could do this:

<pre><code>internal static void AssignNewArrayItem&lt;T&gt;(ref T[] Items, T Item) 
 where T : &lt;base class name&gt;
</code></pre>

blocks|key|1938876|text|你有没有试过这个：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1938877|internal+static+void+AssignNewArrayItem<T>(ref+T[]+Items,+T+Item)

++++++++Items[Items.Length+-+1]+=+Item;

}|code-block|syntax|javascript|1938878|我认为在这里使用List<T>会是更好的选择。|offset|length|style|CODE|1938879|entityMap^0|0|0|8|7|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]]|$1|G|3|H|5|6|7|Q|8|@$I|R|J|S|K|L]]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

Have you tried this:

<pre><code>internal static void AssignNewArrayItem&lt;T&gt;(ref T[] Items, T Item)
{
 if (Items != null)
 {
 Array.Resize(ref Items, Items.Length + 1);
 Items[Items.Length - 1] = Item;
 }
 else
 Items = new T[] { Item };
}
</code></pre>

I think using a <code>List&lt;T&gt;</code> would be the better option here though.

You can use generic constraints, the constraint will only accept objects that inherit from the class <code>Xml.CLASSNAME</code>

<pre><code>internal static void AssignNewArrayItem&lt;T&gt;(ref T[] Items, T Item) where T: Xml.CLASSNAME
{
 if (Items != null)
 {
 Array.Resize(ref Items, Items.Length + 1);
 Items[Items.Length - 1] = Item;
 }
 else
 Items = new Xml.CLASSNAME[] { Item };
}
</code></pre>

I have this method:

<pre><code>internal static void AssignNewArrayItem(ref Xml.CLASSNAME[] Items, Xml.CLASSNAME Item)
{
 if (Items != null)
 {
 Array.Resize(ref Items, Items.Length + 1);
 Items[Items.Length - 1] = Item;
 }
 else
 Items = new Xml.CLASSNAME[] { Item };
}
</code></pre>

At the moment I have about 10 overloaded versions where <code>CLASSNAME</code> is different but they all do the exact same thing. Is there any way I can have <code>CLASSNAME</code> as a generic object and cast the vars to achieve the same result?

I am open to other suggestions to acheive the same result if I am going about this in the wrong way as well.
