给属性添加校验,可以避免用户填写不支持的数据,减少开发不必要的错误处理逻辑。
1.属性必填
通过标注RequiredAttitude支持属性必填
using GrapeCity.Forguncy.Commands; using GrapeCity.Forguncy.Plugin; using System.ComponentModel; using System.ComponentModel.DataAnnotations; namespace MyPlugin { [Icon("pack://application:,,,/MyPlugin;component/Resources/Icon.png")] [Designer("MyPlugin.Designer.MyPluginCommandDesigner, MyPlugin")] public class MyPluginCommand : Command { [Required] public string Name { get; set; } } }

using GrapeCity.Forguncy.Commands; using GrapeCity.Forguncy.Plugin; using System.ComponentModel; using System.ComponentModel.DataAnnotations; namespace MyPlugin { [Icon("pack://application:,,,/MyPlugin;component/Resources/Icon.png")] [Designer("MyPlugin.Designer.MyPluginCommandDesigner, MyPlugin")] public class MyPluginCommand : Command { [MaxLength(6)] [MinLength(1)] public string Name { get; set; } } }
- 效果:
