WPF实现拍照截图功能(WPFMediaKit 调用摄像头和拍照)

1.下载WPFMediaKit包
2.XAML界面

3.后端逻辑

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
using WPFMediaKit.DirectShow.Controls;

namespace 拍照截图
{
    /// 

    /// MainWindow.xaml 的交互逻辑
    /// 
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
            string[] inputNames = MultimediaUtil.VideoInputNames;
            m_VideoCaptureElement.VideoCaptureSource = inputNames[0];
        }

        private void button1_Click(object sender, RoutedEventArgs e)
        {
            //调用默认摄像头
            RenderTargetBitmap bmp = new RenderTargetBitmap((int)m_VideoCaptureElement.ActualWidth, (int)m_VideoCaptureElement.ActualHeight, 96, 96, PixelFormats.Default);
            bmp.Render(m_VideoCaptureElement);
            BitmapEncoder encoder = new JpegBitmapEncoder();
            encoder.Frames.Add(BitmapFrame.Create(bmp));
            //命名格式
            string now = DateTime.Now.Year + "" + DateTime.Now.Month + "" + DateTime.Now.Day + "" + DateTime.Now.Hour + "" + DateTime.Now.Minute + "" + DateTime.Now.Second;
            //保存路径D盘根目录
            string filename = "D:\\" + now + ".jpg";
            FileStream fstream = new FileStream(filename, FileMode.Create);
            encoder.Save(fstream);
            fstream.Close();
            MessageBox.Show("图片已经保存到D盘根目录");


        }
    }
}

注意:
1.界面引用组件需要加一句

xmlns:WPFMediaKit="clr-namespace:WPFMediaKit.DirectShow.Controls;assembly=WPFMediaKit"

2.截图保存到D盘根目录,路径可以自己设置.
