c# - 如何在可观察集合中设置值？

Question

我有这个代码:

  private ObservableCollection<Workspace> _OpenWorkspaces;
  public ObservableCollection<Workspace> OpenWorkspaces {
                            get { return _OpenWorkspaces; }
                            set { _OpenWorkspaces = value; }
                                                 }

如何设置值？ (这样不行)

OpenWorkspaces.id =1; 
OpenWorkspaces.Name ="Jon";

Answer 1

要设置特定项目的属性，您必须指定其索引:

OpenWorkspaces[0].id =1; 
OpenWorkspaces[0].Name ="Jon";

如果你想对所有项目都这样做，使用循环:

foreach(var workspace in OpenWorkspaces)
{
    workspace.id =1; 
    workspace.Name ="Jon";
}

(当然假设您已经在集合中有项目；您可以使用 Add 方法添加它们)
