属性校验

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
   1. 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;
using System.Threading.Tasks;

namespace MyPlugin
{
    [Icon("pack://application:,,,/MyPlugin;component/Resources/Icon.png")]
    [Designer("MyPlugin.Designer.MyPluginServerCommandDesigner, MyPlugin")]
    public class MyPluginServerCommand : Command, ICommandExecutableInServerSideAsync
    {
        [Required]
        public string Name { get; set; }

        public async Task<ExecuteResult> ExecuteAsync(IServerCommandExecuteContext dataContext)
        {
            return new ExecuteResult();
        }
        public override CommandScope GetCommandScope()
        {
            return CommandScope.ExecutableInServer;
        }
    }
}

2. 效果  

2. 校验长度 1. 通过MaxLengthAttribute和MinLengthAttribute支持长度校验

using GrapeCity.Forguncy.Commands;
using GrapeCity.Forguncy.Plugin;
using System.ComponentModel;
using System.ComponentModel.DataAnnotations;
using System.Threading.Tasks;

namespace MyPlugin
{
    [Icon("pack://application:,,,/MyPlugin;component/Resources/Icon.png")]
    [Designer("MyPlugin.Designer.MyPluginServerCommandDesigner, MyPlugin")]
    public class MyPluginServerCommand : Command, ICommandExecutableInServerSideAsync
    {
        [MaxLength(6)]
        [MinLength(1)]
        public string Name { get; set; }

        public async Task<ExecuteResult> ExecuteAsync(IServerCommandExecuteContext dataContext)
        {
            return new ExecuteResult();
        }
        public override CommandScope GetCommandScope()
        {
            return CommandScope.ExecutableInServer;
        }
    }
}
