如果我不知道c＃中的结构，如何访问对象的内容？

Question

I have an object and I don't know its structure until runtime. So is there any way to access data from the object ?

Thanks.

PS: I can't think of any other details to provide, please ask me if this isn't enough!

Answer 1

Well, you can do with with reflection. For example:

public static void ShowProperties(object o)
{
    if (o == null)
    {
        Console.WriteLine("Null: no properties");
        return;
    }
    Type type = o.GetType();
    var properties = type.GetProperties(BindingFlags.Public 
                                        | BindingFlags.Instance);
    // Potentially put more filtering in here
    foreach (var property in properties.Where
                 (p => p.CanRead && p.GetIndexParameters().Length == 0))
    {
        Console.WriteLine("{0}: {1}", property.Name, property.GetValue(o, null));
    }
}

Look at the Type API for ways to get methods, events, fields, nested types etc.

看看反射

Answer 3

You can use reflection to determine what properties, methods, and fields an object has. take a look at the methods on the Type type
