c# - 如何将对象添加到现有类对象

Question

我有一个类对象:

[XmlRoot(ElementName = "Tag")]
public class Tag
{
    [XmlElement(ElementName = "TagId")]
    public string TagId { get; set; }
    [XmlElement(ElementName = "TagTitle")]
    public string TagTitle { get; set; }
}

[XmlRoot(ElementName = "LocTags")]
public class LocTags
{
    [XmlElement(ElementName = "Tag")]
    public Tag[] Tag { get; set; }
}

[XmlRoot(ElementName = "test")]
public class test
{
    [XmlElement(ElementName = "ID")]
    public string ID { get; set; }
    [XmlElement(ElementName = "Name")]
    public string Name { get; set; }
    [XmlElement(ElementName = "LocTags")]
    public LocTags LocTags { get; set; }
}

我已经有这样的数据:

test:
    id=1
    Name="abc"
    locTags
       tag
           tagId=1
           tagTitle="xyz"

    id=2
    name="qwe"
    ...

我想 test=1 添加新对象到 Tag，应该得到结果:

test:
    id=1
    Name="abc"
    locTags
        tag
            tagId=1
            tagTitle="xyz"

            tagId=2
            tagTitle="pqr"
     id=2
     name="qwe"
     ...

我该怎么做？

编辑

List<Tag> tagNew = test.locTags.Tag.ToList();
tagNew.Add(new Tag
{
    TagTitle = "pqr",
    TagId = "2"
});

test.locTags.Tag = tagNew;

但最后一行给我错误:

Error 10 Cannot implicitly convert type 'System.Collections.Generic.List' to 'Tag[]'

Answer 1

制作Tag[]标记为 List<Tag>然后使用 test.LocTagXY.Tags.Add(newTag)

如果您希望继续使用数组，请使用 Pradeep Kumar 的 test.locTags.Tag = tagNew.ToArray()
