C#海康威视无法加载DLL“..\bin\HCNetSDK.dll”

项目场景

c#海康威视：System.DllNotFoundException:“无法加载 DLL“…\bin\HCNetSDK.dll”: 找不到指定的模块。 (异常来自 HRESULT:0x8007007E)。”

问题描述

将海康威视的SDK直接复制到我的项目中时，使用到SDK中的方法就出现这个异常。

将demo里的dll放在bin文件夹和bin\Debug文件夹里时也会出错。

原因分析

这个肯定是路径出错了，不然不会报这个找不到指定模块的异常。

解决方案

在代码中选中方法函数，右键转到定义：

将\bin\HCNetSDK.dll改成\Debug\HCNetSDK，这样就不会报错了。
