Type.IsNestedAssembly 属性
获取一个值,通过该值指示 Type 是否是嵌套的并且只能在它自己的程序集内可见。
**命名空间:**System
**程序集:**mscorlib(在 mscorlib.dll 中)
语法
声明
Public ReadOnly Property IsNestedAssembly As Boolean
用法
Dim instance As Type
Dim value As Boolean
value = instance.IsNestedAssembly
public bool IsNestedAssembly { get; }
public:
virtual property bool IsNestedAssembly {
bool get () sealed;
}
/** @property */
public final boolean get_IsNestedAssembly ()
public final function get IsNestedAssembly () : boolean
属性值
如果 Type 是嵌套的并且仅在它自己的程序集中可见,则为 true;否则为 false。
备注
如果当前 Type 表示某种泛型类型的类型参数,则此属性始终返回 false。
TypeAttributes.VisibilityMask 选择可见性属性 (Attribute)。
示例
下面的示例声明一个在本身的程序集中具有可见性的嵌套类,并显示其 IsNestedAssembly 属性 (Property) 值。
Imports System
Imports Microsoft.VisualBasic
' Nest a class.
Class MyClassA
Friend Class MyClassB
End Class 'MyClassB
End Class 'MyClassA
Class MyTestClass
Public Shared Sub Main()
' Get the type of the nested class.
Dim myTypeB As Type = GetType(MyClassA.MyClassB)
' Get the IsNestedAssembly property of the nested class.
Console.WriteLine(ControlChars.Cr + "The IsNestedAssembly property value of MyClassB is {0}.", myTypeB.IsNestedAssembly.ToString())
End Sub 'Main
End Class 'MyTestClass
using System;
// Nest a class.
class MyClassA
{
internal class MyClassB
{
}
}
class MyTestClass
{
public static void Main(string[] args)
{
// Get the type of the nested class.
Type myTypeB = typeof(MyClassA.MyClassB);
// Get the IsNestedAssembly property of the nested class.
Console.WriteLine("\nThe IsNestedAssembly property value of MyClassB is {0}.", myTypeB.IsNestedAssembly.ToString());
}
}
using namespace System;
// Nest a class.
ref class MyClassA
{
internal:

};
int main()
{
// Get the type of the nested class.
Type^ myTypeB = MyClassA::MyClassB::typeid;
// Get the IsNestedAssembly property of the nested class.
Console::WriteLine( "\nThe IsNestedAssembly property value of MyClassB is {0}.", myTypeB->IsNestedAssembly );
}
import System.*;
// Nest a class.

{

} //MyClassB
} //MyClassA
class MyTestClass
{
public static void main(String[] args)
{
// Get the type of the nested class.
Type myTypeB = MyClassA.MyClassB.class.ToType();
// Get the IsNestedAssembly property of the nested class.
Console.WriteLine("\nThe IsNestedAssembly property value of "
+"MyClassB is {0}.",System.Convert.ToString(
myTypeB.get_IsNestedAssembly()));
} //main
} //MyTestClass
