How do I get a list of all the properties of a class?
You can use Reflection to do this: (from my library - this gets the names and values)
public static Dictionary DictionaryFromType(object atype)
{
if (atype == null) return new Dictionary();
Type t = atype.GetType();
PropertyInfo[] props = t.GetProperties();
Dictionary dict = new Dictionary();
foreach (PropertyInfo prp in props)
{
object value = prp.GetValue(atype, new object[]{});
dict.Add(prp.Name, value);
}
return dict;
}
This thing will not work for properties with an index - for that (it's getting unwieldy):
public static Dictionary DictionaryFromType(object atype,
Dictionary indexers)
{
/* replace GetValue() call above with: */
object value = prp.GetValue(atype, ((indexers.ContainsKey(prp.Name)?indexers[prp.Name]:new string[]{});
}
Also, to get only public properties: (see MSDN on BindingFlags enum)
/* replace */
PropertyInfo[] props = t.GetProperties();
/* with */
PropertyInfo[] props = t.GetProperties(BindingFlags.Public)
This works on anonymous types, too!
To just get the names:
public static string[] PropertiesFromType(object atype)
{
if (atype == null) return new string[] {};
Type t = atype.GetType();
PropertyInfo[] props = t.GetProperties();
List propNames = new List();
foreach (PropertyInfo prp in props)
{
propNames.Add(prp.Name);
}
return propNames.ToArray();
}
And it's just about the same for just the values, or you can use:
GetDictionaryFromType().Keys
// or
GetDictionaryFromType().Values
But that's a bit slower, I would imagine.
