现有一个结构体
public struct Desc<br /> {<br /> private byte val1;<br /> [Description("一个属性")]<br /> public byte des<br /> {<br /> get { return val1; }<br /> set { val1 = value; }<br /> }</p> <p> ///...以下省略<br /> }获取Description代码：string str = "";<br /> Desc desc = new Desc();</p> <p> ////不用反射 获取属性的特性<br /> PropertyDescriptor pd = TypeDescriptor.GetProperties(typeof(Desc))["des"];<br /> DescriptionAttribute description = pd == null ? null : pd.Attributes[typeof(DescriptionAttribute)] as DescriptionAttribute;<br /> str = description == null ? "" : description.Description;</p> <p> ////用反射 获取属性的特性<br /> PropertyInfo pi = typeof(Desc).GetProperty("des");<br /> foreach (object obj in pi.GetCustomAttributes(false))<br /> {<br /> if (obj is DescriptionAttribute)<br /> str=(obj as DescriptionAttribute).Description;<br /> }</p> <p> ////不用反射 获取结构体的特性<br /> AttributeCollection attributes = TypeDescriptor.GetAttributes(desc);//or typeof(Desc)<br /> DescriptionAttribute da = (DescriptionAttribute)attributes[typeof(DescriptionAttribute)];<br /> if(attributes.Contains(da))<br /> str = da.Description;</p> <p> ////用反射 获取结构体的特性<br /> Type myType = typeof(Desc);<br /> foreach (object obj in myType.GetCustomAttributes(false))<br /> {<br /> if (obj is DescriptionAttribute)<br /> str = (obj as DescriptionAttribute).Description;<br /> }
