这里类把RICHTEXTBOX的内容打印到DOCUMENT里 using System; using System.Collections.Generic; using System.Text; using System.Windows.Forms; using System.Drawing.Printing; using System.Runtime.InteropServices; namespace WindowsApplication3.ControlPrint.PrintClass { public class MyRichTextBox { /* 使用方式 ControlPrint.PrintClass.MyRichTextBox MyText= new WindowsApplication3.ControlPrint.PrintClass.MyRichTextBox(richTextBox1);
