Question

Dim xtab As XElement = Nothing
Dim nodes = From nodeToTake In customUIXml.Descendants().Elements("tab") _
            Where nodeToTake.Attribute("label").Value = "MyTab"
            Select nodeToTake

For Each tab As XElement In nodes
    xtab = tab
Next

和

int i = 0;
foreach (string item in titl)
{
    //new instance of Data
    Type keyType = item.GetType();
    XmlSerializer keySerializer = GetTypeSerializer(keyType.AssemblyQualifiedName);
    i = i + 1;
    if (i % 2 == 0)
    {
        writer.WriteStartElement("tTime");
    }
    else
    {
        writer.WriteStartElement("tText");
    }
    if (keyType != typeof(string)) { writer.WriteAttributeString("type", keyType.AssemblyQualifiedName); }
    keySerializer.Serialize(writer, item);
    writer.WriteEndElement();
}

我将XML格式化为：

#region " GetTypeSerializer "

private static readonly Dictionary<string, XmlSerializer> _serializers = new Dictionary<string, XmlSerializer>();
private static readonly object _deadbolt = new object();
private XmlSerializer GetTypeSerializer(string type)
{
    if (!_serializers.ContainsKey(type))
    {
        lock (_deadbolt)
        {
            if (!_serializers.ContainsKey(type))
            {
                _serializers.Add(type,new XmlSerializer(Type.GetType(type)));

            }
        }
    }
    return _serializers[type];
}

#endregion

我有一个字符串，我正在创建XML文件但是我无法知道这个字符串标签来自哪里？可能是它来自某个地方的keyType但是我没有得到它怎么样？我不希望此字符串节点出现在此XML

中

Answer 1

嗯，XmlSerializer类显式序列化文档，文档（格式良好）包含根元素。因此，XmlSerializer似乎将typename作为根元素的element-Name。

Answer 2

你的代码告诉序列化程序Serialize是一个string类型的元素，而不是只写文本。

使用XmlWriter.WriteString代替XmlSerializer.Serialize - 代替：

keySerializer.Serialize(writer, item);

使用

writer.WriteString(item);

具体来说，这个：

var titl = new List<string> {"aaa", "bbb", "ccc"};

int i = 0;
foreach (string item in titl)
{
    //new instance of Data
    i = i + 1;
    if (i % 2 == 0)
    {
        writer.WriteStartElement("tTime");
    }
    else
    {
        writer.WriteStartElement("tText");
    }
    writer.WriteString(item);
    writer.WriteEndElement();
}

会产生这个

<tText>aaa</tText>
<tTime>bbb</tTime>
<tText>ccc</tText>

为什么我在XML中获取<string>节点
