一、问题描述： 异常来自 HRESULT ： 0x8004021F

这是同事在做GeoDatabase 方面的开发时遇到的问题，我拿到他的源代码分析一下，发现程序代码逻辑上并没有什么Bug 。用百度搜索下，有且仅只找到两条相关记录，都是求救的贴子，下文毫无解决办法，看了等于白看，心里稍微安慰的是知道以前有人也遇到过类似的问题，算是前有来者了，自己并不孤独。可是这还是无济于事，问题依然还是问题。

二、问题分析：

下面是自己参考ArcGIS 开发帮助文档写的创建FeatureClass 的代码实例，调试时还是会弹出前面所描述的错误，用IFeatureDataset 创建要素类时弹出的好像是license 权限不够，估计是license 没有签出的缘故。

三、问题解决方法：

经过分析确定是 license 权限不够，因此我们只需将与此相关的 license （ esriLicenseProductCode .esriLicenseProductCodeEngineGeoDB ） 签出即可。修改 license 初始化代码，签出相关的 license 授权，即解决了问题。
