将List <{Anon：string}>传递给C＃中的函数

var list = new List<MyClass>();
var myStringList = (from myClass in list
                  select new {myClass.StringField}).ToList();
var processedStrings = processStrings(myStringList);

List<string> processStrings(List<string> stringsToProcess) {}

myStringList

ArgumentType type \'System.Collections.Generic.List<{StringField:string}>\' is not assignable to parameter type \'System.Collections.Generic.List<string>\'

var list = new List<MyClass>();
var myStringList = (from myClass in list
              select myClass.StringField).ToList();
var processedStrings = processStrings(myStringList);

select myClass.StringField

var list = new List<MyClass>();
var myStringList = (
from myClass in list                  
select myClass.StringField).ToList();
var processedStrings = processStrings(myStringList);
