XML 使用 C# 编辑文件

XML Edit to file using C#

我正在开发一个 WPF 应用程序,我有一个简单的 XML 文件,我正在使用 'XmlDocument' 对其进行解析,并且在 readinh 部分工作正常。 我希望用户能够添加、编辑或删除任何节点并将这些更改保存到文件中。

我尝试使用 'XElement',但它似乎更改了实例本身而不是文件。

我的 XML 文件看起来像这样:

<Configuration>
    <A_0.04_5>
        <ML407Configuration>
            <AM_Amp>10</AM_Amp>
            <AMRJ_Amp>10</AMRJ_Amp>
            <FM_Freq>20</FM_Freq>
            <FM_Phase_Shift>20</FM_Phase_Shift>
        </ML407Configuration>
        <BertConfiguration>
            <BERT_LR>25.78125</BERT_LR>
            <BERT_PRBS>7</BERT_PRBS>
            <BERT_Scaling>1000</BERT_Scaling>
        </BertConfiguration>
    </A_0.04_5>
    <B_1.333_0.15>
        <ML407Configuration>
            <AM_Amp>10</AM_Amp>
            <AMRJ_Amp>10</AMRJ_Amp>
            <FM_Freq>20</FM_Freq>
            <FM_Phase_Shift>20</FM_Phase_Shift>
        </ML407Configuration>
        <BertConfiguration>
            <BERT_LR>25.78125</BERT_LR>
            <BERT_PRBS>7</BERT_PRBS>
        </BertConfiguration>
    </B_1.333_0.15>

    <C_4_0.05>
        <ML407Configuration>
            <BUJ_LR>25</BUJ_LR>
            <BUJ_Pattern>7</BUJ_Pattern>
            <PM_BUJ_Amp>7</PM_BUJ_Amp>
            <BUJ_Amp>80</BUJ_Amp>
            </ML407Configuration>
        <BertConfiguration>
            <BERT_LR>25.78125</BERT_LR>
            <BERT_PRBS>7</BERT_PRBS>
        </BertConfiguration>
    </C_4_0.05> 
</Configuration>

我试过的是:

string filePath = Environment.GetFolderPath(Environment.SpecialFolder.Desktop)+"/Configuration.xml";
XElement xml = XElement.Load(filePath);
// This seems to remove the node from xml instance and not from the file
// Should I save the file again or is there another way to do it
// Same applies for add and edit
xml.Elements("C_4_0.05").Remove();

看到很多类似的问题,不知道有没有直接改成文件的

XElement.Load loads an XML structure from a file into memory. Any changes you make to that structure are also done in memory. If you want to write those changes back to a file (technically called serialization) you need to call XElement.Save.
