我尝试在c#中修改xshd文件以编程方式更改元素Color的属性前景。我试图使用xmlatrattribute来访问它并改变它，但它没有工作。我怎样才能改变呢?下面是我的xshd文件

 <?xml version="1.0"?>

使用LINQ试试:

XDocument doc = XDocument.Load("file.xml");
XNamespace ns = "http://icsharpcode.net/sharpdevelop/syntaxdefinition/2008";
var element = doc.Descendants(ns + "Color").First(x => x.Attribute("name").Value == "String");
element.SetAttributeValue("foreground", "VALUECOLOR");
doc.Save("file.xml");
