示例

下面的代码示例显示用户定义的方法 Mymethod 的属性。

using System;
using System.Reflection;

class AttributesSample
{
    public void Mymethod (int int1m, out string str2m, ref string str3m)
    {
        str2m = "in Mymethod";
    }

    public static int Main(string[] args)
    {
        Console.WriteLine ("Reflection.MethodBase.Attributes Sample");

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

        // Get the method Mymethod on the type.
        MethodBase Mymethodbase = MyType.GetMethod("Mymethod");

        // Display the method name.
        Console.WriteLine("Mymethodbase = " + Mymethodbase);

        // Get the MethodAttribute enumerated value.
        MethodAttributes Myattributes = Mymethodbase.Attributes;

        // Display the flags that are set.
        PrintAttributes(typeof(System.Reflection.MethodAttributes), (int) Myattributes);
        return 0;
    }

    public static void PrintAttributes(Type attribType, int iAttribValue)
    {
        if (!attribType.IsEnum)
        {
            Console.WriteLine("This type is not an enum.");
            return;
        }

        FieldInfo[] fields = attribType.GetFields(BindingFlags.Public | BindingFlags.Static);
        for (int i = 0; i < fields.Length; i++)
        {
            int fieldvalue = (int)fields[i].GetValue(null);
            if ((fieldvalue & iAttribValue) == fieldvalue)
            {
                Console.WriteLine(fields[i].Name);
            }
        }
    }
}

Imports System.Reflection

Class AttributesSample

    Public Sub Mymethod(ByVal int1m As Integer, ByRef str2m As String, ByRef str3m As String)
        str2m = "in Mymethod"
    End Sub

    Public Shared Function Main(ByVal args() As String) As Integer
        Console.WriteLine("Reflection.MethodBase.Attributes Sample")

        ' Get the type.
        Dim MyType As Type = Type.GetType("AttributesSample")

        ' Get the method Mymethod on the type.
        Dim Mymethodbase As MethodBase = MyType.GetMethod("Mymethod")

        ' Display the method name.
        Console.WriteLine("Mymethodbase = {0}.", Mymethodbase)

        ' Get the MethodAttribute enumerated value.
        Dim Myattributes As MethodAttributes = Mymethodbase.Attributes

        ' Display the flags that are set.
        PrintAttributes(GetType(System.Reflection.MethodAttributes), CInt(Myattributes))
        Return 0
    End Function 'Main

    Public Shared Sub PrintAttributes(ByVal attribType As Type, ByVal iAttribValue As Integer)
        If Not attribType.IsEnum Then
            Console.WriteLine("This type is not an enum.")
            Return
        End If
        Dim fields As FieldInfo() = attribType.GetFields((BindingFlags.Public Or BindingFlags.Static))
        Dim i As Integer
        For i = 0 To fields.Length - 1
            Dim fieldvalue As Integer = CType(fields(i).GetValue(Nothing), Int32)
            If (fieldvalue And iAttribValue) = fieldvalue Then
                Console.WriteLine(fields(i).Name)
            End If
        Next i
    End Sub
End Class

此代码生成以下输出：

注解

所有成员都有一组属性，这些属性是相对于特定成员类型定义的。

若要获取， MethodAttributes请先获取类型。 从类型中获取方法。 从方法中获取 MethodAttributes.

实施者说明

使用 Attributes 属性可确定方法是否为 public、 private、 final、 virtual等。
