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：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); 最后的话
