How to loop on field names of a class

Question

I have got a class which contains more then 150 fields. i need the name of fields (not value) in an array.

because its very hard and not a good approach to write 150

Answer 1

for all public + nonpublic instance fields:

var fields = typeof(YourType).GetFields(
    BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Instance);
var names = Array.ConvertAll(fields, field => field.Name);

or in VS2005 (comments):

FieldInfo[] fields = typeof(YourType).GetFields(
    BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Instance);
string[] names = Array.ConvertAll(fields,
    delegate(FieldInfo field) { return field.Name; });
