现有一个结构体

public struct Desc { private byte val1; [Description("一个属性")] public byte des { get { return val1; } set { val1 = value; } } ///...以下省略 }获取Description代码：string str = ""; Desc desc = new Desc(); 不用反射 获取属性的特性 PropertyDescriptor pd = TypeDescriptor.GetProperties(typeof(Desc))["des"]; DescriptionAttribute description = pd == null ? null : pd.Attributes[typeof(DescriptionAttribute)] as DescriptionAttribute; str = description == null ? "" : description.Description; 用反射 获取属性的特性 PropertyInfo pi = typeof(Desc).GetProperty("des"); foreach (object obj in pi.GetCustomAttributes(false)) { if (obj is DescriptionAttribute) str=(obj as DescriptionAttribute).Description; } 不用反射 获取结构体的特性 AttributeCollection attributes = TypeDescriptor.GetAttributes(desc);//or typeof(Desc) DescriptionAttribute da = (DescriptionAttribute)attributes[typeof(DescriptionAttribute)]; if(attributes.Contains(da)) str = da.Description; 用反射 获取结构体的特性 Type myType = typeof(Desc); foreach (object obj in myType.GetCustomAttributes(false)) { if (obj is DescriptionAttribute) str = (obj as DescriptionAttribute).Description; }
