如何在c#中基于属性进行排序

本文关键字：属性 排序 于属性 | 更新日期: 2023-09-27 18:08:19

我在c#中有下面的代码，我试图生成xml。

foreach (Component compCategories in categories)
{
    GenerateXML(xml, compCategories);
}
private void GenerateXML(XmlWriter xml, Component compCategory)
{
    xml.WriteStartElement("category");
    xml.WriteAttributeString("id", compCategory.Id.ItemId.ToString());
string order = compCategory.Title;
    xml.WriteAttributeString("order", order);
    Component detailCategory = compCategory.ComponentValue("Detail");
    if (detailCategory != null)
    {
        xml.WriteAttributeString("detail", detailCategory.Id.ItemId.ToString());
    }
    Component catArtwork = compCategory.ComponentValue("Artwork");
    if (catArtwork != null)
    {
        Component summaryArtwork = catArtwork.ComponentValue("Summary");
        if (summaryArtwork != null)
        {
            String CatImageUrl = PublishBinary(summaryArtwork);
            xml.WriteAttributeString("image", CatImageUrl);
        }
    }
    xml.WriteElementString("title", compCategory.StringValue("Title").ToString());
    xml.WriteElementString("summary", compCategory.StringValue("Summary").ToString());
    xml.WriteElementString("linktext", compCategory.StringValue("Linktext").ToString());
    xml.WriteEndElement();
}

我如何根据"order"(上面突出显示的)属性值对xml呈现进行排序，我不打算使用XSLT，但是LINQ很好。

请建议! !

谢谢

如何在c#中基于属性进行排序

您能在生成XML之前对集合进行排序吗?

var ordered = categories.OrderBy(cat=>cat.Title);
foreach (Component compCategories in ordered)
{
    GenerateXML(xml, compCategories);
}

在调用Generatexml()之前对列表进行排序:

foreach (Component compCategories in categories.OrderBy(c => c.Title).ToList())
{
    GenerateXML(xml, compCategories);
}
