如何从BindingSource读取BindType prop？ [英] How to read BindType prop from BindingSource?

问题描述

我正在寻找读取对象类型绑定到 BindingSource 。

I'm looking for reading object type bind to BindingSource.

在调试器模式下，我已经钻取了BndingSource对象，我发现非公开属性名为 BindType 包含感兴趣的信息。

In debugger mode I've drilled down BndingSource object and I've found non-public property named "BindType" what contains interested info.

（还发现属性 ItemType 什么也包含这样的信息 - 但是我不知道如果BS.Count == 0）

(Also found property "ItemType" what contains also such info - but I'm not sure it will work if BS.Count == 0)

请问如何阅读/访问该信息？

Can you please advice how to read / access that info ?

推荐答案

我已经找到了解决方案 - 可以帮助某人：）

I've found solution myself - giving it here - maybe helps someone :)

    private static string ObjectHostedByBS (BocBindingSource bs) {
        if (bs == null) return string.Empty;


        ITypedList tl = bs as ITypedList;
        var a = tl.GetItemProperties(null);

        // no prop read
        if (a == null || a.Count == 0) return null;

        return a[0].ComponentType.Name;
    }
