Xml文件,请注意这只是一个示例,因为我希望程序在我开始填充此存储库之前工作

<repo>
<Packages>
    <TheFirstPackage id="00001" longname="Mozilla Firefox" appver="3.6.3" pkgver="0.01" description="Mozilla Firefox is a free and open source web browser descended from the Mozilla Application Suite and managed by Mozilla Corporation. A Net Applications statistic  put Firefox at 24.52% of the recorded usage share of web browsers as of March 2010[update], making it the second most popular browser in terms of current use worldwide after Microsoft's Internet Explorer." cat="WWW" rlsdate="4/8/10" pkgloc="http://google.com"/>
</Packages>
<categories>
    <WWW longname="World Wide Web" description="Software that's focus is communication or primarily uses the web for any particular reason."> </WWW>
    <Fun longname="Entertainment & Other" description="Music Players, Video Players, Games, or anything that doesn't fit in any of the other categories."> </Fun>
    <Work longname="Productivity" description="Application's commonly used for occupational needs or, stuff you work on"> </Work>
    <Advanced longname="System & Security" description="Applications that protect the computer from malware, clean the computer, and other utilities."> </Advanced>
</categories>
</repo>

C#代码的一小部分

//Loading the Package and Category lists
                //The info from them is gonna populate the listboxes for Category and Packages
                Repository.Load("repo.info");
                XmlNodeList Categories = Repository.GetElementsByTagName("categories");
                foreach (XmlNode Category in Categories)
                {
                    CategoryNumber++;
                    CategoryNames[CategoryNumber] = Category.Name;
                    MessageBox.Show(CategoryNames[CategoryNumber]);
                }

Messagebox.Show()只是为了确保它获得正确的结果

Answer 1

&符号在XML中具有特殊含义.你需要改变:

Entertainment & Other

在这个字符的位置使用字符实体引用:

Entertainment & Other

这同样适用于System & Security.
