循环所有属性 [英] Loop ALL Properties

问题描述

我正在试图循环第三方

控件的属性。例如，我有一个文本框，其最大长度位于MyTextBox.Properties.MaxLength的
- 而不是dotnet文本框，而不是
MyTextBox.MaxLength。如果我循环内置的dotnet控件，它会发现

属性没问题。但循环通过第三方控件，

Properties.MaxLength未列出。我希望找到它如何使用反射来命名它，所以我可以使用GetValue和SetValue来动态地设置

控件的值，直到运行时才知道它们的类型。如何获得

访问循环控件的所有属性？


Dim t As Type = ctl.GetType

For Each pp As PropertyInfo in t.GetProperties（）

Console.WriteLine（" {0} = {1}"，pp.Name，pp.GetValue（ctl，Nothing））

I am going in circles trying to loop through properties on 3rd party
controls. For example, I have a textbox that has its maximum length located
at MyTextBox.Properties.MaxLength - instead of the dotnet textbox which is
MyTextBox.MaxLength. If I loop a built in dotnet control, it finds the
property no problem. But looping through the 3rd party control,
Properties.MaxLength does not get listed. I was hoping to find how it names
it using reflection, so I could use GetValue and SetValue to dyanmically set
values of controls without knowing their type until runtime. How can I gain
access to loop ALL the properties of a control?

Dim t As Type = ctl.GetType
For Each pp As PropertyInfo In t.GetProperties()
Console.WriteLine("{0} = {1}", pp.Name, pp.GetValue(ctl, Nothing))
Next

推荐答案

嗨Derek，


我有没有得到它是正确的MyTextBox.Properties是你自己的数组

''属性''，像字典？如果是这样，它与''真实财产'的关系如何，

'本地'为一个班级？

Hi Derek,

Did I get it right that MyTextBox.Properties is sort of your own array of
''properties'', like dictionary? If so, that how it relates to ''real properties'',
''native'' for a class?

你应该递归循环。

第三方Developer Express文本框控件。它有很多属性。不能

弄清楚如何循环并获得所有这些。

嗨Derek，


我是否理解MyTextBox.Properties有点像你自己的一堆

''属性''，就像字典一样？如果是这样，它是如何与''真实的

属性''相关联，''本地'为一个类？
