get custom fields only from a sharepoint list

Question

Can anyone tell me how can I get the custom fields from a sharepoint list? I don't want to get all the fields like hidden, just the custom ones or the ones in the default view. The end result will be to save the schemaxml for each field in an xml file.

I am trying to do it like this:

SPfieldCollection fields = list.DefaultView.ViewFields 
foreach(SPField field in fields) 
{ 
.... 
}

Powershell or C# will be very helpful. Thank you

You are asking for three different things here. They can all be done, you just need to refine your requirement a little. You can certainly 1) get all the non-hidden fields, 2) get all the fields that are different from the list template, and 3) get all the fields from a particular view. First decide what constitutes a "custom field", and proceed from there.

Whether you need to do this for one specific list or dynamically across all the lists in a site collection(for example) also will play into your solution design.
