MethodBase.IsPublic 属性

获取一个值，该值指示这是否是一个公共方法。

**命名空间:**System.Reflection
**程序集:**mscorlib（在 mscorlib.dll 中）

语法

声明
Public ReadOnly Property IsPublic As Boolean
用法
Dim instance As MethodBase
Dim value As Boolean

value = instance.IsPublic

public bool IsPublic { get; }

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

/** @property */
public final boolean get_IsPublic ()

public final function get IsPublic () : boolean

属性值

如果此方法是公共的，则为 true；否则为 false。

备注

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，则它受到保护而且无法容易地进行访问。若要访问非公共方法，请在 GetMethod 中将 BindingFlags 屏蔽设置为 NonPublic。

示例

Class methodbase1
    
    Public Shared Function Main() As Integer
    
        Console.WriteLine(ControlChars.Cr + "Reflection.MethodBase")
        
        'Get the MethodBase of a method.
        
        'Get the type
        Dim MyType As Type = Type.GetType("System.MulticastDelegate")
        
        'Get and display the method
        Dim Mymethodbase As MethodBase = _
           MyType.GetMethod("RemoveImpl", BindingFlags.NonPublic)
        
        Console.Write(ControlChars.Cr _
           + "Mymethodbase = " + Mymethodbase.ToString())
        
        Dim Myispublic As Boolean = Mymethodbase.IsPublic
        If Myispublic Then
            Console.Write(ControlChars.Cr _
               + "Mymethodbase is a public method")
        Else

               + "Mymethodbase is not a public method")
        End If 
        Return 0
    End Function
End Class
