如何动态指定Linq OrderBy参数？

Question

如何orderby使用我作为参数的值指定传递给参数的参数？例如：List<Student> existingStudends = new List<Student>{ new Student {...}, new Student {...}}目前执行：List<Student> orderbyAddress = existingStudends.OrderBy(c => c.Address).ToList();而不是c.Address，我如何将其作为参数？例 string param = "City"; List<Student> orderbyAddress = existingStudends.OrderByDescending(c => param).ToList();

Answer 1

这是使用反射的可能性...

var param = "Address";    

var propertyInfo = typeof(Student).GetProperty(param);    

var orderByAddress = items.OrderBy(x => propertyInfo.GetValue(x, null));
