推荐答案

你好.

这取决于您如何过滤绑定列表.

我更喜欢使用linq.

例如:

Hello.

it depends on how you are filtering the bound list.

I prefer to use linq.

For example:

var foundPerson = from p in PersonEntity
              where p.Surname.StartsWith("sh")
              select p;

MyBoundList = foundPerson.ToList();

它比这快得多:

It''s very faster than this:

foreach (Person person in PersonEntity)
{
    if (person.Surname.StartsWith("sh"))
        MyBoundList.Add(person);
}
