MVS4.4 Samples C# MvCameraControlNet_V2 Grab

新建Winform 应用类型选择命令行因为会自动添加

using System.Drawing;
using System.Drawing.Imaging;

的引用避免手动添加其实是懒得;

其实之前写过一篇类似的但是那个是旧版本新版本据说是事件,调试半天我没仔细看

贴出官方README.txt

工业相机SDK提供了两套.Net接口，命名空间分别为：
1. namespace MvCamCtrl.NET：	示例程序位于 MvCameraControlNet 文件夹下。
2. namespace MvCameraControl：	示例程序位于 MvCameraControlNet_V2 文件夹下。推荐使用 namespace MvCameraControl 的接口namespace MvCamCtrl.NET：
1. 基于 .Net Framework 3.5 开发，演示如何将SDK的C语言接口封装成.Net接口，再调用封装的.Net接口实现SDK功能
2. 源码位于 MvCameraControlNet\MVCameraSDK\Source\MVCamera.csnamespace MvCameraControl：
1. 基于 .Net Framework 4.0 开发，是SDK提供的新的.Net程序集（MvCameraControl.Net.dll）
2. 库文件位于客户端安装路径下的 Development\DotNet\AnyCpu\MvCameraControl.Net.dll，同时提供了win32 和 win64版本
3. 具体的调用方法可参考文档目录下的工业相机SDK开发指南(.Net)
