You could use the XDocument class:

您可以使用XDocument类:

var doc = XDocument.Load("test.xml");
var address = doc.Root.Element("address");
if (address != null)
{
    address.Value = "new value";
}
doc.Save("test.xml");

Let's say you have the following XML file:

假设您有以下XML文件:

<root>
    <address>myaddr</address>
</root>

And you want to do the replacement. There are many options. Some are explicitly modifying XML, others are translating your XML to classes, modifying and translating back to XML (serialization). Here is one of the ways do do it:

你想做替换。有很多选择。一些是显式修改XML,另一些是将XML转换为类,修改和转换回XML(序列化)。以下是其中一种方法:

XDocument doc = XDocument.Load("myfile.xml");
doc.Root.Element("address").Value = "new address"
doc.Save("myfile.xml")
