问题描述
我是编程的新手，但尝试在 VS2019 中运行我的第一个应用程序，C# .NET。我想从我的 USB 显微镜中取出一个 Snapshop。我找到了 OZEKI SDK 库，并且能够连接和查看显微镜中的图像。 Ozeki 在 youtube 上有一个教程：
https://www.youtube.com/watch?v=xjMAfMAix9c
和他们的网站，
https://www.camera-sdk.com/p_6553-how-to-take-a-picture-snapshot-and-save-it-as-.jpg-in-c-.html
但是当我尝试运行应用程序时，我收到消息： “images.save(curentpath)”对象不包含“save”的定义，也不能访问......”
代码：
using System;
using System.Drawing;
using System.Windows.Forms;
using Ozeki.Media;
using Ozeki.Camera;
namespace WindowsFormsApp3
{
public partial class Form1 : Form
{
private DrawingImageProvider _imageProvider;
private MediaConnector _connector;
private VideoViewerWF _videoViewerWf;
private SnapshotHandler _snapshotHandler;
private IWebCamera _webCamera;
public Form1()
{
InitializeComponent();
_imageProvider = new DrawingImageProvider();
_connector = new MediaConnector();
_snapshotHandler = new SnapshotHandler();
_videoViewerWf = new VideoViewerWF();
SetVideoViewer();
}
private void SetVideoViewer()
{
CameraBox.Controls.Add(_videoViewerWf);
_videoViewerWf.Size = new Size(260,180);
_videoViewerWf.BackColor = Color.Black;
_videoViewerWf.TabStop = false;
_videoViewerWf.Location = new Point(14,19);
_videoViewerWf.Name = "_videoViewerWf";
}
private void button_Connect_Click(object sender,EventArgs e)
{
_webCamera = new WebCamera();
if (_webCamera != null)
{
_connector.Connect(_webCamera.VideoChannel,_imageProvider);
_connector.Connect(_webCamera.VideoChannel,_snapshotHandler);
_videoViewerWf.SetimageProvider(_imageProvider);
_webCamera.Start();
_videoViewerWf.Start();
}
}
private void button_Saveto_Click(object sender,EventArgs e)
{
var result = folderbrowserDialog1.ShowDialog();
if (result == DialogResult.OK)
TextBox_Saveto.Text = folderbrowserDialog1.Selectedpath;
}
private void Btn_Snapshot_Click(object sender,EventArgs e)
{
var path = TextBox_Saveto.Text;
CreateSnapShot(path);
}
private void CreateSnapShot(string path)
{
var date = DateTime.Now.Year + "y-" + DateTime.Now.Month + "m-" + DateTime.Now.Day + "d-" +
DateTime.Now.Hour + "h-" + DateTime.Now.Minute + "m-" + DateTime.Now.Second + "s";
string currentpath;
if (String.IsNullOrEmpty(path))
currentpath = date + ".jpg";
else
currentpath = path + "\\" + date + ".jpg";
var snapShotimage = _snapshotHandler.TakeSnapshot().ToImage();
snapShotimage.Save(currentpath,System.Drawing.Imaging.ImageFormat.Jpeg);
}
}
}

在此先感谢您的帮助。
解决方法
好的，我做到了。更改：
var snapShotImage = _snapshotHandler.TakeSnapshot().ToImage();
到
var snapShotImage = _snapShot.TakeSnapshot().ToImage() as System.Drawing.Image;
