i有一个应用程序可以接收名称和来自用户的日期，然后将值放在图像上

推荐答案

假设你的图像每次都在同一个地方有名称和日期区域，那就不难了：

Assuming your image has the name and date areas in the same place each time, then it's not too difficult:

using (Image i = Image.FromFile(inputPath))
    {
    using (Graphics g = Graphics.FromImage(i))
        {
        g.DrawString("John", Font, Brushes.Black, new PointF(fX, fY1));
        g.DrawString("2018-10-01", Font, Brushes.Black, new PointF(fX, fY2));
        }
    i.Save(outputPath, ImageFormat.Png);
    }
