c# - 将 XML 节点附加到现有 XML 文件

Question

我有以下格式的 XML

<Attachment>
 <AttachmentName>Top Nav Menu.docx</AttachmentName>
 <Subject>Attachment1</Subject>
 <Sender>JameelM@orioninc.com</Sender>
 </Attachment>

我想在附件关闭节点之后附加另一个附件，如上所述。以下是我为编写 xml 文件而编写的代码

 var doc = new XDocument(

                new XDeclaration("1.0", "utf-16", "true"),

                new XProcessingInstruction("test", "value"),

                new XElement("Attachment",new XElement("AttachmentName", attachment.Name),
                                          new XElement("Subject", exchangeEmailInformation.Subject),
                                          new XElement("Sender", exchangeEmailInformation.Sender
                                          )));
            doc.Save(ConfigInformation.BackUpPath + FolderId[index]+"\\Attachments"+index+".xml");

Answer 1

为您的附件创建根节点：

var doc = new XDocument(
    new XDeclaration("1.0", "utf-16", "true"),
    new XProcessingInstruction("test", "value"),
    new XElement("Attachments", 
        new XElement("Attachment", 
            new XElement("AttachmentName", attachment.Name),
            new XElement("Subject", exchangeEmailInformation.Subject),
            new XElement("Sender", exchangeEmailInformation.Sender)
    )));

当您决定附加另一个附件时，加载文档并将附件添加到根目录：

doc.Root.Add(new XElement("Attachment",
    new XElement("AttachmentName", attachment.Name),
    new XElement("Subject", exchangeEmailInformation.Subject),
    new XElement("Sender", exchangeEmailInformation.Sender)
));

我会使用 XMLSerializer 类。在那里，您可以像处理类一样处理您的 XML 文件。看看吧，你会喜欢的：）

加载 XML -> 在代码中使用类（修改、删除、添加）-> 序列化回 XML
