C#.net如何在GDI+绘图过程中添加文字？样子就像windows自带的画图软件那样

Answer 1

//下面这两个文件位置根据你的需求，修改成你机子上的绝对位置。
//程序运行完后，会在newFile位置生成一个新文件。
string oldFile = Environment.CurrentDirectory + "\\test.jpg";
string newFile = Environment.CurrentDirectory + "\\test1.jpg";
Image image = Image.FromFile(oldFile);
Graphics graphic = Graphics.FromImage(image);
graphic.DrawString("绘画时间：2010年11月24日11:31:10", new Font("幼圆", 24f, FontStyle.Regular), new SolidBrush(Color.Black), 100f, 100f);
image.Save(newFile);
image.Dispose();
graphic.Dispose();
