除了您自己的自定义代码之外，您还没有做很多事情，但是我有一个 LINQ示例 [

You haven''t given much to go on apart from your own custom code, but I''d have a read of this LINQ Samples[^]

But this is taken from the article

public void Linq47() 
{ 
    List<product> products = GetProductList(); 
  
    var categoryNames = ( 
        from p in products 
        select p.Category) 
        .Distinct(); 
  
    Console.WriteLine("Category names:"); 
    foreach (var n in categoryNames) 
    { 
        Console.WriteLine(n); 
    } 
}
</product>
