准备工作
这个窗体继承子基类窗体frmwithokcancel1，如果你对frmwithokcancel1还不了解，请移步 （二十五）c#winform自定义控件-有确定取消的窗体（一） 查看
开始
添加一个form，命名frminputs，继承frmwithokcancel1
一个多参构造函数

用处及效果
用处：当需要输入多个文本时可用
效果：
调用示例
1 frminputs frm = new frminputs("动态多输入窗体测试",
2 new string[] { "姓名", "电话", "身份证号", "住址" },
3 new dictionary<string, hzh_controls.textinputtype>() { { "电话", hzh_controls.textinputtype.regex }, { "身份证号", hzh_controls.textinputtype.regex } },
4 new dictionary<string, string>() { { "电话", "^1\\d{10}$" }, { "身份证号", "^\\d{18}$" } },
5 new dictionary<string, keyboardtype>() { { "电话", keyboardtype.uckeybordernum }, { "身份证号", keyboardtype.uckeybordernum } },
6 new list<string>() { "姓名", "电话", "身份证号" });
7 frm.showdialog(this);
