Type.IsPublic 属性

定义

命名空间:

System

程序集:

System.Runtime.dll

程序集:

netstandard.dll

程序集:

mscorlib.dll

获取一个值，该值指示 Type 是否声明为公共类型。

public:
 property bool IsPublic { bool get(); };

public bool IsPublic { get; }

member this.IsPublic : bool

Public ReadOnly Property IsPublic As Boolean

属性值

Boolean

如果 true 声明为公共类型且不是嵌套类型，则为 Type；否则为 false。

实现

IsPublic

示例

下面的示例创建一个实例 MyTestClass ，检查 IsPublic 属性，并显示结果。

using namespace System;

// Declare MyTestClass as public.
public ref class TestClass{};

int main()
{
   TestClass^ testClassInstance = gcnew TestClass;
   
   // Get the type of myTestClassInstance.
   Type^ testType = testClassInstance->GetType();
   
   // Get the IsPublic property of the myTestClassInstance.
   bool isPublic = testType->IsPublic;
   Console::WriteLine( "Is {0} public? {1}", testType->FullName, isPublic);
}

using System;

public class TestClass
{
}

public class Example
{
   public static void Main()
   {
      TestClass testClassInstance = new TestClass();
      // Get the type of myTestClassInstance.
      Type   testType = testClassInstance.GetType();
      // Get the IsPublic property of testClassInstance.
      bool isPublic = testType.IsPublic;
      Console.WriteLine("Is {0} public? {1}", testType.FullName, isPublic);
   }
}
// The example displays the following output:
//        Is TestClass public? True

Public Class TestClass
End Class

Public Class Example
   Public Shared Sub Main()
      Dim testClassInstance As New TestClass()
      
      ' Get the type of testClassInstance.
      Dim testType As Type = testClassInstance.GetType()
      ' Get the IsPublic property of testClassInstance.
      Dim isPublic As Boolean = testType.IsPublic
      Console.WriteLine("Is {0} public? {1}", testType.FullName, isPublic)
   End Sub 
End Class 
' The example displays the following output:
'       Is TestClass public? True

对于嵌套类，忽略和的结果，并 IsPublic IsNotPublic 只注意和的结果 IsNestedPublic IsNestedPrivate 。

注解

不要将与嵌套类型一起使用;改为使用 IsNestedPublic 。

如果当前 Type 表示泛型类型的类型参数，则此属性返回 true 。

TypeAttributes.VisibilityMask 选择可见性特性。
