如何在c#中通过反射获得命名空间中的所有类?
当前回答
就像@aku的答案,但使用扩展方法:
string @namespace = "...";
var types = Assembly.GetExecutingAssembly().GetTypes()
.Where(t => t.IsClass && t.Namespace == @namespace)
.ToList();
types.ForEach(t => Console.WriteLine(t.Name));

var types = Assembly.GetExecutingAssembly().GetTypes()
.Where(t => t.IsClass && t.Namespace == @namespace)
.ToList();
types.ForEach(t => Console.WriteLine(t.Name));
如果其中一个类型子类化了另一个程序集中的类型,你可能会发现LoaderException错误,下面是一个修复:
// Setup event handler to resolve assemblies
AppDomain.CurrentDomain.ReflectionOnlyAssemblyResolve += new ResolveEventHandler(CurrentDomain_ReflectionOnlyAssemblyResolve);
Assembly a = System.Reflection.Assembly.ReflectionOnlyLoadFrom(filename);
a.GetTypes();
// process types here
// method later in the class:
static Assembly CurrentDomain_ReflectionOnlyAssemblyResolve(object sender, ResolveEventArgs args)
{
return System.Reflection.Assembly.ReflectionOnlyLoad(args.Name);
}
这应该有助于加载在其他程序集中定义的类型。
希望有帮助!
Namespaces are actually rather passive in the design of the runtime and serve primarily as organizational tools. The Full Name of a type in .NET consists of the Namespace and Class/Enum/Etc. combined. If you only wish to go through a specific assembly, you would simply loop through the types returned by assembly.GetExportedTypes() checking the value of type.Namespace. If you were trying to go through all assemblies loaded in the current AppDomain it would involve using AppDomain.CurrentDomain.GetAssemblies()
在一行中通过Namespace名称的一部分获取所有类:
var allClasses = Assembly.GetExecutingAssembly().GetTypes().Where(a => a.IsClass && a.Namespace != null && a.Namespace.Contains(@"..your namespace...")).ToList();
对于特定的程序集,命名空间和ClassName:
var assemblyName = "Some.Assembly.Name"
var nameSpace = "Some.Namespace.Name";
var className = "ClassNameFilter";
var asm = Assembly.Load(assemblyName);
var classes = asm.GetTypes().Where(p =>
p.Namespace == nameSpace &&
p.Name.Contains(className)
).ToList();
注意:项目必须引用程序集
