[C#] XML to Object / Generic | XML泛型轉換

Recently, I have to some things related to XML in the work, so I prepared some tools and wrote the method of converting XML to Object, but it is not very beautiful on using.
最近工作上需要做一些跟XML有關的東西，所以先準備些工具，一開始也沒多想就寫了將XML轉成Object的方法，但是使用上有點不漂亮。

static object XmlToObj(XDocument xml, Type objType)
{
    object obj;
    try
    {
        XmlSerializer serializer = new XmlSerializer(objType);
        using (TextReader reader = new StringReader(xml.ToString()))
        {
            obj = serializer.Deserialize(reader);
        }
    }
    catch (Exception e)
    {
        Console.WriteLine(e.Message);
        return null;
    }
    return obj;
}

Using above XmlToObj, it need to cast it first, the code isn't feel so beauty, so I decide rewrite it to generic method.
使用上面的XmlToObj，會需要做轉型才能使用，code感覺不是很美，所以我決定改寫成泛型的方式。

var result = (PurchaseOrder)XmlToObj(doc, typeof(PurchaseOrder));

After rewrite to generic method, it look like it.
轉成泛型的方式後，變成如下。

static T XmlToGeneric(XDocument xml)
{
    T obj;
    try
    {
        XmlSerializer serializer = new XmlSerializer(typeof(T));
        using (TextReader reader = new StringReader(xml.ToString()))
        {
            obj = (T)serializer.Deserialize(reader);
        }
    }
    catch (Exception e)
    {
        Console.WriteLine(e.Message);
        obj = default(T);
    }
    return obj;
}

It's more beauty on using.
使用上就漂亮了很多

var result = XmlToGeneric(doc);

Compare both method, the generic method looks like more elegant.
比較兩者，使用泛型的方法看來簡潔許多。

//to generic
var result1 = XmlToGeneric(doc);
//to object
var result2 = (PurchaseOrder)XmlToObj(doc, typeof(PurchaseOrder));
