Type.IsPublic 屬性

定義

命名空間:

System

組件:

System.Runtime.dll

組件:

netstandard.dll

組件:

mscorlib.dll

取得值，指出 Type 是否宣告為公用。

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

public bool IsPublic { get; }

member this.IsPublic : bool

Public ReadOnly Property IsPublic As Boolean

屬性值

Boolean

如果 Type 已宣告為公用而且不是巢狀型別，則為 true，否則為 false。

實作

IsPublic

範例

下列範例會建立的實例 MyTestClass 、檢查 IsPublic 屬性，並顯示結果。

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

針對嵌套類別，請忽略和的結果， IsPublic IsNotPublic 只注意和的結果 IsNestedPublic IsNestedPrivate 。

備註

請勿搭配巢狀型別使用;請改用 IsNestedPublic 。

如果目前 Type 表示泛型型別的型別參數，則這個屬性會傳回 true 。

TypeAttributes.VisibilityMask 選取可見度屬性。
