C# LINQ 获取字段值与字符串数组黑名单不匹配的对象

Question

我有以下代码:

public class MyObject {
  public string Name { get; set; }

  public MyObject(string name) {
    Name = name;
  }  
}

// caller method somewhere
public void myMethod() {
  List<MyObject> myObjects = new List<MyObject>();
  myObjects.Add(new MyObject("Jim"));
  myObjects.Add(new MyObject("David"));
  myObjects.Add(new MyObject("Richard"));
  myObjects.Add(new MyObject("Steve"));

  string[] namesToExclude = new string[] { "Jim", "Steve" };
  List<string> strings = myObjects.Select(m => m.Name).Except(namesToExclude).ToList();
  // replace the above line to result in List<MyObject> with 2 items (David, Richard)
}

我想让这最后一行工作，这样我就可以将列表返回为 List<MyObject>而不是 List<string> .

Answer 1

试试这个:

 var objects = 
      myObjects.Where(m => !namesToExclude.Contains(m.Name)).ToList();
