C#课设

前言

C#课设挺水的(基本题目都很简单)。还是简单记录一下,简单地使用了WPFComboboxGroupBox的控件。


功能需求

获取系统文化和国家信息(CultureInfo 类):在组合框中选择一个国家,则会显示操作系统中该国家的有关信息。
大致情况如下:
C#要求


学习demo

看了下题确实挺简单的,不是很想花时间在WPF这玩意上。
所以到网上抄(x学)了个demo–>参考资料链接3
可以通过ComboBox设置一个SelectionChanged的函数来进行变化。有了这个东西,然后修改GroupBox的内容就好了。(所以不看了,等会直接写代码吧
把界面调整一下,然后有了以下MainWindow.xaml文件代码

写代码

有了上面的代码,界面就有了,下面写一下用户选择的逻辑即可,这里关联了两个类,RegionInfo类和CultureInfo

this.groupBox.Header = myregion.DisplayName + "国家和文化信息"; //国家
this.groupBox.Content = "国家全名:" + myregion.DisplayName+"\n";
this.groupBox.Content += "国家英文名:" + myregion.EnglishName+"\n";

if (myregion.IsMetric)
this.groupBox.Content += "是否使用公制:是\n";
else

CultureInfo MyCultureInfo = new CultureInfo(text);
this.groupBox.Content += "语言名称:" + MyCultureInfo.Parent.DisplayName+"\n";
}

}
}

然后运行的情况,首先选择国家
选择国家

然后选中之后就可以看到显示了
选择结果

前两个是微软的说明文档,第三个是一个combobox的一个demo。

如果对您有帮助,请我喝杯咖啡?
