C# 截图ScreenCapture,保存

简化版：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Drawing;
using System.Windows.Forms;
using System.IO;
using System.Drawing.Imaging;

namespace ConsoleApp346
{
    class Program
    {
        [STAThread]
        static void Main(string[] args)
        {
            ScreenCapture();

        }

        static void ScreenCapture()
        {
            Rectangle bounds = Screen.GetBounds(System.Drawing.Point.Empty);
            using (Bitmap bitmap = new Bitmap(bounds.Width, bounds.Height))
            {
                using (Graphics g = Graphics.FromImage(bitmap))
                {
                    g.CopyFromScreen(System.Drawing.Point.Empty, System.Drawing.Point.Empty, bounds.Size);
                }
                string fullName = Directory.GetCurrentDirectory() + "\\" + DateTime.Now.ToString("yyyyMMddHHmmssffff") + ".jpg";
                bitmap.Save(fullName, ImageFormat.Jpeg);
            }
        }
    }
}

效果如图：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Drawing;
using System.Windows.Forms;
using System.IO;
using System.Drawing.Imaging;

namespace ConsoleApp346
{
class Program
{
[STAThread]
static void Main(string[] args)
{
ScreenCapture();

}

static void ScreenCapture()
{
Rectangle bounds = Screen.GetBounds(System.Drawing.Point.Empty);
using (Bitmap bitmap = new Bitmap(bounds.Width, bounds.Height))
{
using (Graphics g = Graphics.FromImage(bitmap))
{
g.CopyFromScreen(System.Drawing.Point.Empty, System.Drawing.Point.Empty, bounds.Size);
}

using (SaveFileDialog sfd = new SaveFileDialog())
{
sfd.Title = "Save Pictures";
sfd.InitialDirectory = Directory.GetCurrentDirectory();
sfd.RestoreDirectory = true;
sfd.Filter = "bmp files(*.bmp)|*.bmp|All Files(*.*)|*.*";
sfd.FileName = DateTime.Now.ToString("yyyyMMddHHmmssffff") + ".jpg";
if (sfd.ShowDialog() == DialogResult.OK)
{
bitmap.Save(sfd.FileName, ImageFormat.Jpeg);
}
}
}
}
}
}

效果如下所示：

 2 using System.Collections.Generic;
 3 using System.Linq;
 4 using System.Text;
 5 using System.Threading.Tasks;
 6 using System.Drawing;
 7 using System.Windows.Forms;
 8 using System.IO;

30                 }

36                     sfd.RestoreDirectory = true;

41                         bitmap.Save(sfd.FileName, ImageFormat.Jpeg);
42                     }
43                 }
44             }
45         }
46     }
47 }
