我有一堂课。
Public Class Foo Private _Name As String Public Property Name() As String Get Return _Name End Get Set(ByVal value As String) _Name = value End Set End Property Private _Age As String Public Property Age() As String Get Return _Age End Get Set(ByVal value As String) _Age = value End Set End Property Private _ContactNumber As String Public Property ContactNumber() As String Get Return _ContactNumber End Get Set(ByVal value As String) _ContactNumber = value End Set End Property End Class
我想遍历上述类的属性。例如;
Public Sub DisplayAll(ByVal Someobject As Foo) For Each _Property As something In Someobject.Properties Console.WriteLine(_Property.Name & "=" & _Property.value) Next End Sub
使用反射:
Type type = obj.GetType(); PropertyInfo[] properties = type.GetProperties(); foreach (PropertyInfo property in properties) { Console.WriteLine("Name: " + property.Name + ", Value: " + property.GetValue(obj, null)); }
对于 Excel - 必须添加哪些工具/参考项才能访问 BindingFlags,因为列表中没有“System.Reflection”条目
编辑:您还可以将 BindingFlags 值指定为type.GetProperties():
type.GetProperties()
BindingFlags flags = BindingFlags.Public | BindingFlags.Instance; PropertyInfo[] properties = type.GetProperties(flags);
这会将返回的属性限制为公共实例属性(不包括静态属性、受保护属性等)。
您不需要指定BindingFlags.GetProperty,在调用时使用它type.InvokeMember()来获取属性的值。
BindingFlags.GetProperty
type.InvokeMember()
