枚举一个对象的属性并将其复制到另一个相同类型的对象

Enumerate and copy properties from one object to another object of same type(枚举一个对象的属性并将其复制到另一个相同类型的对象)

问题描述

我使用第三方控件将一些数据导出为不同的格式.该控件有一个属性ExportSettings.但它是只读的.

I use a third party control which exports some data to different formats. The control has a property ExportSettings. But it is read-only.

我必须手动设置它的属性，例如

I've to manually set its properties like

ctrl.ExportSettings.Paging = false;
ctr.ExportSettings.Background = Color.Red;

所以我从用户那里得到了 ExportSettings 对象，我想将它设置为控件.

So I get the ExportSettings object from the user and I want to set it to the control.

如何将其所有成员值复制到用户控件?

How can I copy all its member values to the user control?

推荐答案

尝试基于反射的克隆:

private object CloneObject(object o)
{
    Type t = o.GetType();
    PropertyInfo[] properties = t.GetProperties();

    Object p = t.InvokeMember("", System.Reflection.BindingFlags.CreateInstance, 
        null, o, null);

    foreach (PropertyInfo pi in properties)
    {
        if (pi.CanWrite)
        {
            pi.SetValue(p, pi.GetValue(o, null), null);
        }
    }

    return p;
}
