Assembly.GetExportedTypes 方法

定义

命名空间:

System.Reflection

程序集:

System.Runtime.dll

Source:

Assembly.cs

获取此程序集中定义的公共类型，这些公共类型在程序集外可见。

public:
 virtual cli::array <Type ^> ^ GetExportedTypes();

public virtual Type[] GetExportedTypes ();

abstract member GetExportedTypes : unit -> Type[]
override this.GetExportedTypes : unit -> Type[]

Public Overridable Function GetExportedTypes () As Type()

返回

Type[]

一个数组，表示此程序集中定义并在程序集外可见的类型。

例外

NotSupportedException

程序集是动态程序集。

FileNotFoundException

无法加载从属程序集。

示例

下面的代码示例定义了具有各种访问级别的许多类，并调用 GetExportedTypes 以显示从程序集外部可见的类。

using namespace System;
using namespace System::Reflection;

namespace ExportedClassExample
{
    public ref class Example sealed
    {
    private:
        Example() 
        {
        }

    public:
        void static EnumerateExportedTypes()
        {
            for each (Type^ exportedType in 
                Example::typeid->Assembly->GetExportedTypes())
            {
                Console::WriteLine(exportedType);
            }
        }
    };

    public ref class PublicClass
    {
    public:
        ref class PublicNestedClass 
        { 
        };

    protected:
        ref class ProtectedNestedClass 
        { 
        };

    internal:
        ref class FriendNestedClass 
        { 
        };

    private:
        ref class PrivateNestedClass
        { 
        };
    };

    ref class FriendClass
    {
    public:
        ref class PublicNestedClass
        { 
        };

    protected:
        ref class ProtectedNestedClass 
        { 
        };

    internal:
        ref class FriendNestedClass 
        { 
        };

    private:
        ref class PrivateNestedClass 
        { 
        };
    };
}

int main()
{
    ExportedClassExample::Example::EnumerateExportedTypes();

    return 0;
}

using System;
using System.Reflection;

public class Example
{
    public static void Main()
    {
        foreach (Type t in typeof(Example).Assembly.GetExportedTypes())
        {
            Console.WriteLine(t);
        }
    }
}

public class PublicClass
{
    public class PublicNestedClass {}

    protected class ProtectedNestedClass {}

    internal class FriendNestedClass {}

    private class PrivateNestedClass {}
}

internal class FriendClass
{
    public class PublicNestedClass {}

    protected class ProtectedNestedClass {}

    internal class FriendNestedClass {}

    private class PrivateNestedClass {}
}

Imports System.Reflection

Public Class Example
    Public Shared Sub Main()
        For Each t As Type In GetType(Example).Assembly.GetExportedTypes()
            Console.WriteLine(t)
        Next
    End Sub
End Class

Public Class PublicClass
    Public Class PublicNestedClass
    End Class

    Protected Class ProtectedNestedClass
    End Class

    Friend Class FriendNestedClass
    End Class

    Private Class PrivateNestedClass
    End Class
End Class

Friend Class FriendClass
    Public Class PublicNestedClass
    End Class

    Protected Class ProtectedNestedClass
    End Class

    Friend Class FriendNestedClass
    End Class

    Private Class PrivateNestedClass
    End Class
End Class

注解

程序集外部唯一可见的类型是嵌套在其他公共类型中的公共类型和公共类型。 若要检索程序集中的所有类型（包括非公共类型），请使用 GetTypes 方法。
