搞个类测试一下:
class Student { [CategoryAttribute("学生信息"), DescriptionAttribute("姓名")] public string Name { get; set; } [CategoryAttribute("学生信息"), DescriptionAttribute("年龄")] public int Age { get; set; } [CategoryAttribute("学生信息"), DescriptionAttribute("性别")] public string Sex { get; set; } [CategoryAttribute("学生成绩"), DescriptionAttribute("语文")] public int Chinese { get; set; } [CategoryAttribute("学生成绩"), DescriptionAttribute("英语")] public int English { get; set; } [CategoryAttribute("学生成绩"), DescriptionAttribute("数学")] public int Math { get; set; } }
界面后台:
public partial class FormMain : Form { private Student _xiaoMing = null; public FormMain() { InitializeComponent(); _xiaoMing = new Student() { Name = "小明", Age = 9, Sex = "男", Chinese = 100, English = 98, Math = 120 }; propertyGrid1.SelectedObject = _xiaoMing ; } private void btnShow_Click(object sender, EventArgs e) { MessageBox.Show($"姓名:{_xiaoMing.Name} 年龄:{_xiaoMing.Age} 性别:{_xiaoMing.Sex}\n语文:{_xiaoMing.Chinese} 英语:{_xiaoMing.English} 数学:{_xiaoMing.Math}" ); } // 这一步手动其实没啥用,修改属性值后是直接影响的。 private void btnModify_Click(object sender, EventArgs e) { Student student = propertyGrid1.SelectedObject as Student; _xiaoMing = student; } }▲ 运行后直接显示了
控件的值其实和 SelectedObject
对象成一个绑定的关系,修改控件的值就相当于修改了SelectedObject
的值,类似于 WPF 的绑定。
如果类型不匹配会弹窗提示:
这样还是挺方便的。另外,SelectedObject
属性可取值可赋值。
