Question

我想创建一个接收3个字符串作为参数的方法，并返回一个包含三个属性的对象，这些属性引用这些字符串。

没有要复制的“旧对象”。应该在此方法中创建属性。

是用C＃做反射吗？如果是这样，怎么样？以下是你喜欢的，我无法做到。

protected Object getNewObject(String name, String phone, String email)
{
    Object newObject = new Object();

    ... //I can not add the variables that received by the object parameter here.

    return newObject();
}

Answer 1

如果您想在动态中添加属性，字段等，可以尝试使用 Expando 类

http://msdn.microsoft.com/en-us/library/system.dynamic.expandoobject.aspx

 dynamic newObject = new ExpandoObject();

 newObject.name = name;
 newObject.phone = phone; 
 newObject.email = email

Answer 2

protected dynamic getNewObject(String name, String phone, String email)
{
    return new { name = name, phone = phone, email = email };
}

Answer 3

使用Expando对象的完整示例就像这样

protected dynamic getNewObject(String name, String phone, String email)
    {


        // ... //I can not add the variables that received by the object parameter here.
        dynamic ex = new ExpandoObject();
        ex.Name = name;
        ex.Phone = phone;
        ex.Email = email;
        return ex;
    }

    private void button1_Click_2(object sender, EventArgs e)
    {
        var ye = getNewObject("1", "2", "3");
        Console.WriteLine(string.Format("Name = {0},Phone = {1},Email={2}", ye.Name, ye.Phone, ye.Email));
    }

使用c＃中的反射向对象添加属性
