如何从BindingSource的阅读BindType道具？ [英] How to read BindType prop from BindingSource?

问题描述

我在寻找阅读对象类型绑定到的BindingSource 。

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

在调试模式下，我钻下去BndingSource对象，我发现一个名为 BindType 包含什么感兴趣的信息。非公共财产

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

（又发现属性的ItemType 什么也包含了这样的信息 - 但我不知道它会工作，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)

您可以请指教如何读/访问这些信息？

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

推荐答案

我已经找到自己的解决方案 - 给它在这里 - 也许可以帮助别人：）

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;
	}
