Type.IsPublic Property


取得值,指出 Type 是否宣告為公用。Gets a value indicating whether the Type is declared public.

 property bool IsPublic { bool get(); };
public bool IsPublic { get; }
member this.IsPublic : bool
Public ReadOnly Property IsPublic As Boolean

Property Value


如果 true 已宣告為公用而且不是巢狀類型,則為 Type,否則為 falsetrue if the Type is declared public and is not a nested type; otherwise, false.



下列範例會建立 MyTestClass的實例、檢查 IsPublic 屬性,並顯示結果。The following example creates an instance of MyTestClass, checks for the IsPublic property, and displays the result.

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 IsPublicIsNotPublic 的結果,並只注意 IsNestedPublicIsNestedPrivate的結果。For nested classes, ignore the results of IsPublic and IsNotPublic and pay attention only to the results of IsNestedPublic and IsNestedPrivate.


請勿使用搭配巢狀型別;請改用 IsNestedPublicDo not use with nested types; use IsNestedPublic instead.

如果目前的 Type 表示泛型型別的類型參數,則這個屬性會傳回 trueIf the current Type represents a type parameter of a generic type, this property returns true.

TypeAttributes.VisibilityMask 選取可見度屬性。TypeAttributes.VisibilityMask selects the visibility attributes.
