与我在这里找到的不同,我想在我的 xml 文档中维护语法,而序列化并没有涉及到这一点。我希望能够在 xml 文档中添加另一个“任务”标签……加载信息不是问题,我之前必须处理过这个问题……但这是。

optionsbtn.Text = "Options"; //make the options button's text options
var items = ToDochkbox.Items; //create a private "var" items symbolizing the Checkbox's items array
XDocument xmlDoc = XDocument.Load("tasksdoc.xml"); //load the xml document (in bin or release)
var q = from c in xmlDoc.Descendants("root") //go "within" the <root> </root> tag in the file
select (string)c.Element("task"); //find the first <task></task> tag
foreach (string N in q) //now cycle through all the <task></task> tags and per cycle save them to string "N"

itemstr = title +" - " + details; //set a variable to equal the title string, a - with spaces on each end, and then the details string
items.Add(itemstr); //add the variable itemstr (above) to the the checkbox list
}
private void optionsbtn_Click(object sender, EventArgs e)
{
new options().Show();//show the options form
}
private void aboutToolStripMenuItem_Click(object sender, EventArgs e)
{
new options().Show();//show the options form
}

foreach (string N in q) //now cycle through all the <task></task> tags and per cycle save them to string "N"
{
items.Add(N); //add the item to the checkbox list
}
}
}
}
还有我的 XML 文档:
<root>
<task>First Task - Create a Task</task>
</root>
