How can I rewrite this LINQ query with reflection

[亡魂溺海] 提交于 2019-12-24 12:33:37

List<Profile> profilesFromUUID = await MobileService.GetTable<Profile>().Where(p => typeof(Profile) .GetProperty(handler.Name + "UUID").GetValue(p) == obj.uuid).ToListAsync(); 回答1: Use the reflection to create the query, not in the query. Consider: public static IQueryable<Profile> Filter( this IQueryable<Profile> source, string

问题 I have this user-defined function: CREATE FUNCTION [dbo].[COUNT_ROWS_TABLE]() RETURNS TINYINT AS BEGIN DECLARE @ROW_COUNT TINYINT SELECT @ROW_COUNT = COUNT(*) FROM EMPLOYEE RETURN @ROW_COUNT END GO The problem is it only works for the table [dbo].[EMPLOYEE] and I don't want to Copy-Paste this function for every table on my database.

C#: Creating lists of generic containers?

本秂侑毒 提交于 2019-12-24 11:44:25
问题 I have a situation in which I have a data container that looks something like this: public class DataContainer<T> { public T GetData { get; private set; } public DataContainer(T data) { this.GetData = data; } } But unfortunately I need to have a list of these containers where the generic parameter of each is not known until runtime and can vary from element to element. I initially attempted to run with something like: IList<DataContainer<dynamic>> containerList = new List<DataContainer

Dynamic object two way data binding

旧街凉风 提交于 2019-12-24 11:40:14
问题 I am trying to build a dynamic data container that allows (some of) the dynamically added properties to be bound to WinForm elements. So far, when I bind a regular object property the binding works fine. Sample: public class CompileTimePropertiesDataContainer { public string TestString = "Hello World"; } and then binding within the form works fine: var component = new CompileTimePropertiesDataContainer(); lblTestString.DataBinding.Add( "Text", component, "TestString", false,

Dynamic pool of workers with MPI for large array C++

南楼画角 提交于 2019-12-24 11:29:46
问题 My question is how to create a dynamic pool of workers with MPI. There is a large (NNN = 10^6-7 elements) 1D array/vector. I should perform some calculations on each cell. This problem is extremely embarrassingly parallel. The idea is (it works fine): each MPI process (when run in parallel) reads common .dat file, puts values in local (to each rank) large vector of size NNN and performs computation on appropriate part of large array, the lenght of this "part" is NNN/nprocs, where "nprocs" is

Comparing dates using Dynamic Action on DatePicker Oracle Apex

走远了吗. 提交于 2019-12-24 11:28:41
问题 I have a date picker where the user simply chooses a date then a Dynamic Action is suppose to send an alert if the user clicks tomorrow(sysdate+1). The Datepicker term is the simple layout. The Dynamic Action--> Name: Valid Date Event: Change Selection type: Item(s) Item(s): datepicker_name Condition: equal to Value: sysdate+1 When I run the program and click any day on the calendar, no alert comes up. I thought the problem was the format. The Dynamic Action sees the date as "DD/MM/YYYY"
