Getting the name of a property in a list

问题

Example

public class MyItems
{
    public object Test1  {get ; set; }
    public object Test2  {get ; set; }
    public object Test3  {get ; set; }
    public object Test4  {get ; set; }
    public List<object> itemList
    {
        get
        {
            return new List<object>
            {
                Test1,Test2,Test3,Test4
            }
        }
    }
}

public void LoadItems()
{
    foreach (var item in MyItems.itemList)
    {
        //get name of item here (asin,  Test1, Test2)
    }
}

I have tried this with reflection.. asin typeof(MyItems).GetFields() etc.. but that doesn't work.

How can I find out which name "item" has? Test1? Test2?? etc...

回答1:

 var test = typeof(MyItems).GetProperties().Select(c=>c.Name);

The above will give you an Enumerable of properties name. if you want to get the name of the properties in the list use:

var test = typeof(MyItems).GetProperties().Select(c=>c.Name).ToList();

EDIT:

From your comment, may be you are looking for :

 foreach (var item in m.itemList)
    {
        var test2 = (item.GetType()).GetProperties().Select(c => c.Name);
    }

回答2:

The "name" of the object is neither "Test1", nor "MyItems[0]".

Both those are just references to the object, that is in effect, nameless.

I do not know of any technique in C# that could give you all the references to an object, given an object, so I do not think what you want is possible, the way you want it.

回答3:

You can access the name of properties with this code (see MSDN)

Type myType =(typeof(MyTypeClass));
// Get the public properties.
PropertyInfo[] myPropertyInfo = myType.GetProperties(BindingFlags.Public|BindingFlags.Instance);

for(int i=0;i<myPropertyInfo.Length;i++)
{
    PropertyInfo myPropInfo = (PropertyInfo)myPropertyInfo[i];
    Console.WriteLine("The property name is {0}.", myPropInfo.Name);
    Console.WriteLine("The property type is {0}.", myPropInfo.PropertyType);
}

But right now I don't know any code to access the name of a reference!
