linq 动态列名排序

http://blog.csdn.net/q107770540/article/details/6133484

private static object GetPropertyValue(object obj, string property)
        {
            System.Reflection.PropertyInfo propertyInfo = obj.GetType().GetProperty(property);
            //Console.WriteLine(propertyInfo.GetValue(obj, null));
            return propertyInfo.GetValue(obj, null);
        } 

调用:

var query = from p in pets orderby  GetPropertyValue(p, "Name") select p; //绿色为要排序的列名
