问题描述

如何在 C# 中获取命名空间中的所有类?

How can I get all classes within a namespace in C#?

推荐答案

你需要向后"做；列出程序集中的所有类型，然后检查每个类型的命名空间:

You will need to do it "backwards"; list all the types in an assembly and then checking the namespace of each type:

using System.Reflection;
private Type[] GetTypesInNamespace(Assembly assembly, string nameSpace)
{
    return 
      assembly.GetTypes()
              .Where(t => String.Equals(t.Namespace, nameSpace, StringComparison.Ordinal))
              .ToArray();
}

用法示例:

Type[] typelist = GetTypesInNamespace(Assembly.GetExecutingAssembly(), "MyNamespace");
for (int i = 0; i < typelist.Length; i++)
{
    Console.WriteLine(typelist[i].Name);
}

对于 .Net 2.0 之前 Assembly.GetExecutingAssembly() 不可用的任何内容，您需要一个小的解决方法来获取程序集:

---

For anything before .Net 2.0 where Assembly.GetExecutingAssembly() is not available, you will need a small workaround to get the assembly:

Assembly myAssembly = typeof(<Namespace>.<someClass>).GetTypeInfo().Assembly;
Type[] typelist = GetTypesInNamespace(myAssembly, "<Namespace>");
for (int i = 0; i < typelist.Length; i++)
{
    Console.WriteLine(typelist[i].Name);
}
