Type.IsPublic 属性

定义

获取一个值,该值指示 Type 是否声明为公共类型。Gets a value indicating whether the Type is declared public.

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

属性值

如果 true 声明为公共类型且不是嵌套类型,则为 Type;否则为 falsetrue if the Type is declared public and is not a nested type; otherwise, false.

实现

示例

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

对于嵌套类, IsPublic忽略和IsNotPublic的结果,并IsNestedPublic只注意和IsNestedPrivate的结果。For nested classes, ignore the results of IsPublic and IsNotPublic and pay attention only to the results of IsNestedPublic and IsNestedPrivate.

注解

不要将与嵌套类型一起使用;改IsNestedPublic为使用。Do not use with nested types; use IsNestedPublic instead.

如果当前Type表示泛型类型的类型参数,则此属性返回trueIf the current Type represents a type parameter of a generic type, this property returns true.
