关于【pd_PrintPage】的错误。
本帖最后由 mucmucll 于 2013-10-15 20:06:49 编辑 最近准备做个POS打印的程序，借鉴了一下这个网页的内容：
http://www.cnblogs.com/weixing/p/3283182.html
新建了一个windows窗口项目，然后在默认创建的Form1上面拖了两个button控件，然后就直接粘贴下面的代码，无法编译，总是提示：
错误 CS1061: “Pos_Test.Form1”不包含“pd_PrintPage”的定义，并且找不到可接受类型为“Pos_Test.Form1”的第一个参数的扩展方法“pd_PrintPage”(是否缺少 using 指令或程序集引用?)
难道是忘了加命名空间了？请高手指点一下。
