MethodBase.IsPublic 属性

定义

命名空间:

System.Reflection

程序集:

System.Reflection.dll

程序集:

System.Runtime.dll

程序集:

netstandard.dll

程序集:

mscorlib.dll

获取一个值，该值指示这是否是一个公共方法。

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

public bool IsPublic { get; }

member this.IsPublic : bool

Public ReadOnly Property IsPublic As Boolean

属性值

Boolean

如果此方法是公共的，则为 true；否则为 false。

实现

IsPublic

示例

下面的示例使用 IsPublic 属性显示一条消息，该消息指示指定的方法是否是公共方法。

int main()
{
   Console::WriteLine( "\nReflection.MethodBase" );
   
   //Get the MethodBase of a method.
   //Get the type
   Type^ MyType = Type::GetType( "System.MulticastDelegate" );
   
   //Get and display the method
   MethodBase^ Mymethodbase = MyType->GetMethod( "RemoveImpl", static_cast<BindingFlags>(BindingFlags::NonPublic | BindingFlags::Instance) );
   Console::Write( "\nMymethodbase = {0}", Mymethodbase );
   bool Myispublic = Mymethodbase->IsPublic;
   if ( Myispublic )
      Console::Write( "\nMymethodbase is a public method" );
   else
      Console::Write( "\nMymethodbase is not a public method" );

   return 0;
}

/*
Produces the following output

Reflection.MethodBase
Mymethodbase = System.Delegate RemoveImpl (System.Delegate)
Mymethodbase is not a public method
*/

class methodbase
{
   public static int Main(string[] args)
   {

      Console.WriteLine("\nReflection.MethodBase");

      //Get the MethodBase of a method.

      //Get the type
      Type MyType = Type.GetType("System.MulticastDelegate");

      //Get and display the method
      MethodBase Mymethodbase =
         MyType.GetMethod("RemoveImpl",BindingFlags.NonPublic);

      Console.Write("\nMymethodbase = " + Mymethodbase);

      bool Myispublic = Mymethodbase.IsPublic;
      if (Myispublic)
         Console.Write ("\nMymethodbase is a public method");
      else
         Console.Write ("\nMymethodbase is not a public method");

      return 0;
   }
}
/*

Class methodbase1
    
    Public Shared Function Main() As Integer
    
        Console.WriteLine(ControlChars.Cr + "Reflection.MethodBase")

        If Myispublic Then
            Console.Write(ControlChars.Cr _

        Else
            Console.Write(ControlChars.Cr _
               + "Mymethodbase is not a public method")
        End If 
        Return 0
    End Function
End Class

' Mymethodbase is not a public method

注解

若要获取 MethodBase ，请首先获取 类型。 从 类型获取 方法。 从 方法获取 MethodBase 。 如果 MethodBase 或 构造函数不是公共的，则它受到保护，并且无法轻松访问。 若要访问非公共方法，在 中 BindingFlags 将掩码 NonPublic 设置为 GetMethod 。
