Answer 1

假设你坚持一个输入文本框的搜索字词：

// Get an array of search terms... search for as many as you like 
string[] searchTerm = textBoxSearch.Text.ToLower().Split(' '); 

List<Person> searchResult = new List<Person>(); 

foreach (string term in searchTerm) 
{ 
    searchResult.AddRange(People.FindAll(p => p.Name.ToLower().Contains(term) 
     || p.Postort.ToLower().Contains(term))); 
} 

Answer 2

我会做这样的事情（复制和粘贴准备）：

private void buttonSearch_Click(object sender, EventArgs e) 
{ 
     string searchTerm = textBoxSearch.Text.ToLower(); 

     List<string> searchWords = new List<string>(searchTerm.Split(new char[] { ' ' })); 
     List<Person> searchResult = new List<Person>(); 

     foreach (string word in searchWords) 
     { 
      searchResult.AddRange(People.FindAll(p => p.Name.ToLower().Contains(word))); 
      searchResult.AddRange(People.FindAll(p => p.Postort.ToLower().Contains(word))); 
     } 

     listBoxPeople.Items.Clear(); 

     foreach (Person person in searchResult) 
     { 
      listBoxPeople.Items.Add(person.ToListBoxString()); 
     } 

     if (searchResult.Count == 0) 
     { 
      MessageBox.Show("Not found info! try again!"); 
     } 
}
