获取加载程序集的根命名空间（程序集命名空间）

Question

I'm using the GetTypeInfo() method to get the TypeInfo of a class from an assembly.

Through that I'm trying to get the root namespace of that assembly (or is it called assembly namespace?). But I can't find a property in there that gives me that namespace. There is AssemblyQualifiedName which is a string that has the root namespace in it. But there are also a lot of other things in there like version number etc.

How can I get the root namespace of an assembly in .NET Core?

Answer 1

Assemblies don't have namespaces themselves only the types within the assembly. The thing you could be thinking of is the "Assembly Name", that is often the same name as the "Default Namespace" which most types within the assembly will use.

Assembly assembly = //..
string name = assembly.GetName().Name;

The GetName() returns a AssemblyName object that contains the pieces that are used to build up the AssemblyQualifiedName . This function is available in .Net Standard 1.0 so is available on all versions of .NET Core

由于程序集可能有多个名称空间，因此您只能尝试获取所有类型的名称空间：

.GetTypeInfo().Assembly.GetTypes().Select(t => t.Namespace).Distinct();
