我是C#和编程的新手。我能够在控制台中创建所需的程序,但也希望使用Forms来处理一个。尝试从文本框中获取int时遇到问题。尝试从文本框中获取int时出错
在调试我得到错误:
Error 3 'int' does not contain a definition for 'Text' and no extension method 'Text' accepting a first argument of type 'int' could be found (are you missing a using directive or an assembly reference?) D:\Dropbox\Classwork\C_Sharp\InProgress\PaintDeterminator\Paint Determinator Form\Paint Determinator Form\Form1.cs 30 57 Paint Determinator Form
这里是我到目前为止已经编写的代码。

我强烈建议不要定义具有相同名称的局部变量我们的班级成员。不考虑问题范围,它使代码非常难以理解。 – David
只是一个建议 - 不要将您的内部变量命名为与文本框控件相同,这很混乱。 –
我编辑了你的标题。请参阅:“[应该在其标题中包含”标签“](http://meta.stackexchange.com/questions/19190/)”,其中的共识是“不,他们不应该”。 –
