C# LINQ转换为XML。如何查询列表<；T>；使用Linq递归
我正在从结构生成XML文件。某些结构成员在C# LINQ转换为XML。如何查询列表<；T>；使用Linq递归,c#,xml,linq,xelement,C#,Xml,Linq,Xelement,我正在从结构生成XML文件。某些结构成员在列表中类型。我正在使用linq查询，但在某种程度上我被卡住了 我的结构如下所示： public struct Project { public string name; public List<Class> classes; } public struct Class { public string name; public int class_id; public List<Var> v
