为什么会这样(控件中的枚举)

[秋叶园]

this.numberTextBox1.Masked = CustomControls.NumberTextBox.Mask.Decimal;
-->老是在任务列表中有:
变量“Mask”未声明或从未赋值。
可是却能编译，每次用这个控件，看到这个就恶心....
为了解决问题代码如下:

你把这句提到类的外面去写
public enum Mask {None,Decimal,Integer }
枚举也是一种class，写在类里面会当成一种类的嵌套用法
试试看

你的程序正常，任务中的这个报错没问题
可能是编译的一些顺序问题，不是真错了

[秋叶园]

我的是dll了,程序还要还要编译吗？

[kinglht]

this.numberTextBox1.Masked = CustomControls.NumberTextBox.Mask.Decimal;
这条语句在哪里？

[七里十二斋]

你的控件不是标准控件，不是标准控件都可能产生类似的问题，其实是没关系，你的应用程序肯定跑的很好

这是主要的(...代表省略了)

何为标准控件

[秋叶园]

不也是个dll吗
