扩展IEnumerable返回BindingList [英] Extending IEnumerable to Return BindingList

问题描述

在堆栈溢出的上一个问题中，我遇到了一个将EF查询返回给DataGridView的问题。当然我会遇到一个问题。但是，我添加了一个扩展方法，仍然让我困惑，因为它不工作。这似乎应该是，但由于某种原因，它不是。

In a previous question on Stack Overflow, I had run into an issue with returning an EF query to the DataGridView. Of course I'd run into an issue. However, I added an extension method that still has me baffled since it isn't working. It seems like it should, but for some reason it's not.

public static class BindingListEntityExtension
{
    public static BindingList<T> ToBindingList<T>(this IEnumerable<T> entities)
    {
        BindingList<T> rtn = new BindingList<T>();

        foreach (T obj in entities)
        {
            rtn.Add(obj);
        }

        return rtn;
    }
}

任何想法发生了什么？我的实现是这样的：

Any ideas what's going on? My implementation is like so:

MyEntities context = new MyEntities();
tempDataGridView.DataSource = context.Employees.ToBindingList();

推荐答案

正如Ecyrb在上一篇文章中所提到的，BindingList不排序。我确实使用建议的网站/ 来列出我的列表。多谢你们！我的扩展程序现在正在工作。

Got it. As Ecyrb had suggested in a previous post, the BindingList does not sort. I did use the suggested site/ to get my list to sort. Thanks guys! My extension does work now.
