我想作为一个参数传递给一个方法，一个按类型和id分组的列表，如何正确地将其作为一个参数传递并在方法中接收它？我使用的是Visual Studio 2022，groupedDocuments的类型为List<Ideal <$'a，Document>>

public class Document
{  
    public int Id;
    public string DocumentType;
    public string Description;
}
public class Something()
{
     public void DoSomethingA(){
          List<Document> Documents = new List<Document>();
          Documents.Add(new Document { Id = 1, DocumentType = "TypeA", Description = 
          "DescriptionA" });
    Documents.Add(new Document { Id = 2, DocumentType = "TypeB", Description = 
          "DescriptionB" });
    Documents.Add(new Document { Id = 3, DocumentType = "TypeC", Description = 
          "DescriptionC" });
    var groupedDocuments = Documents.GroupBy(item => new { item.DocumentType, item.Id })
   .ToList();
    DoSomethingB(groupedDocuments) // I want to pass groupedDocuments here
    }
    public void DoSomethingB() // how to define this grouped list here in argument?
    {
      // ...Something
    }
}
