我有一个从"编辑、选择性粘贴、将XML粘贴为类"生成的类。
可扩展标记语言：

<?xml version="1.0"?>
<Items version="1.0">
  <Item InputFileName="G:\FileFile.txt">
    <Position X="500" Y="100" Z="150"/>
  </Item>
</Items>

类别：

namespace Produccion.ClassFile
{
/// <comentarios/>
[System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true)]
[System.Xml.Serialization.XmlRootAttribute(Namespace = "", IsNullable = false)]
public partial class Items
{

    private ItemsItem[] itemField;

    private decimal versionField;

    /// <comentarios/>
    [System.Xml.Serialization.XmlElementAttribute("Item")]
    public ItemsItem[] Item
    {
        get
        {
            return this.itemField;
        }
        set
        {
            this.itemField = value;
        }
    }

    /// <comentarios/>

        }

    }

        }

    }

        }
    }
}

public partial class ItemsItemPosition
{

    private decimal xField;

    private decimal yField;

    private decimal zField;

    /// <comentarios/>
    [System.Xml.Serialization.XmlAttributeAttribute()]
    public decimal X
    {
        get
        {
            return this.xField;
        }
        set
        {
            this.xField = value;
        }
    }

    /// <comentarios/>
    [System.Xml.Serialization.XmlAttributeAttribute()]
    public decimal Y
    {
        get
        {
            return this.yField;
        }
        set
        {
            this.yField = value;
        }
    }

    /// <comentarios/>
    [System.Xml.Serialization.XmlAttributeAttribute()]
    public decimal Z
    {
        get
        {
            return this.zField;
        }
        set
        {
            this.zField = value;
        }
    }
}

}
我不知道如何用文件中的数据初始化这个类。
