代码：

public class CashierOut : BaseActivity
{
    [Description("Flag indicates whether break to execution.")]
    [DefaultValue(false)]
    [MyCustomAttribute(ParameterGroups.Extended)]
    public bool CancelExecution { get; set; }
 
    [Description("Flag indicates whether allow exit before declation.")]
    [DefaultValue(true)]
    [MyCustomAttribute(ParameterGroups.Extended)]
    [DisplayName("Exit before declaration?")]
    public bool AllowExitBeforeDeclare { get; set; }
}

我想做这样的事情：

public class CashierOut : BaseActivity
{
    [MyResourceCustom("CashierOut.CancelExecution")]
    public bool CancelExecution { get; set; }
 
    [MyResourceCustom("CashierOut.AllowExitBeforeDeclare")]
    public bool AllowExitBeforeDeclare { get; set; }
}
 
public sealed class MyResourceCustom : Attribute
{
    public string ResourcePath { get; private set; }
 
    public ParameterGroupAttribute(string resourcePath)
    {
        ResourcePath = resourcePath;
 
        // Get attributes attributes value from external resource using the path.
    }
}
