使用XmlTextWriter和XmlTextReader操作Xml文件

具体用法参考如下代码

XmlTextWriter：

XmlTextWriter writer = new XmlTextWriter(strmMetadata, Encoding.UTF8) {
     Formatting = Formatting.Indented
 };
writer.WriteStartDocument();
writer.WriteStartElement("Session");
writer.WriteAttributeString("SID", this.id.ToString());
writer.WriteAttributeString("BitFlags", ((uint) this.BitFlags).ToString("x"));
 
writer.WriteEndElement();
writer.WriteEndDocument();
writer.Flush();

XmlTextReader:

代码分析：

XmlTextReader reader = new mlTextReader(strmMetadata);
while (reader.Read())
{
    string str3;
    if ((reader.NodeType == XmlNodeType.Element) && ((str3 = reader.Name) != null))
    {
        if (!(str3 == "Session"))
        {
            if (str3 == "SessionFlag")
            {
                goto Label_00BB;
            }
            if (str3 == "SessionTimers")
            {
                goto Label_00E1;
            }
            if (str3 == "PipeInfo")
            {
                goto Label_0292;
            }
        }
        else
        {
        }
    }
    continue;
Label_00BB:
    this.oFlags.Add(reader.GetAttribute("N"), reader.GetAttribute("V"));
    continue;
Label_00E1:
    this.Timers.ClientConnected = XmlConvert.ToDateTime(reader.GetAttribute("ClientConnected"), XmlDateTimeSerializationMode.RoundtripKind);
    string attribute = reader.GetAttribute("ClientBeginRequest");
    if (attribute != null)
    {
        this.Timers.ClientBeginRequest = XmlConvert.ToDateTime(attribute, XmlDateTimeSerializationMode.RoundtripKind);
    }
reader.Close();

1，使用while循环配合continue,goto语句来读取节点信息。

2，使用GetAttribute函数时，结果!=null的判断。
