But if there is no solution then I will continue to do it that way. 回答1: Create a DTO (Data Transfer Object) that exposes all your data that you intend to bind to UI elements. Create a property

问题 I asked this question yesterday and got a great response/code example. The only problem is that I forgot to mention that I am forced to work with the .Net Framework 2.0 and can't use the List.Select ( I assume the linq namespace). Does anyone have a good work around for List.Select seen below: class Program { struct ProcessStartTimePair { public Process Process { get; set; } public DateTime StartTime { get; set; } public DateTime ExitTime { get { return DateTime.Now; // approximate value } }

问题 I am having an application which is built in 1.1 framework.This application is now rebuilt in 2.0 framework but due to some reason we have to use some of the pages of 1.1 framework.

问题 I have a .NET 2.0 application. In this application, I need to pass data back to my server. The server exposes a REST-based URL that I can POST data to. When I pass data back to my server, I need to sometimes do so asynchronously, and other times I need a blocking call. In the scenario of the asynchronous call, I need to know when the call is completed. Everything up to this point I understand how to do. Where I get into trouble is, the method that I am working on MUST be static. It's code I

问题 Consider a webmethod which exposes an abstract class: [WebMethod] public void Save(AbstractEntity obj) { // .. } There are several classes inheriting from AbstractEntity like public class Patient : AbstractEntity { // ... } Now I want to enable the webservice consumer to create a new Patient object and save it: service.Save(new Patient { Name = "Doe", Number = "1234567" }); Because "Save" takes an AbstractEntity, there will be no Patient proxy on the client side. I could of course create a

问题 I have data coming from the database in the form of a DataSet . I then set it as the DataSource of a grid control before doing a DataBind() . I want to sort the DataSet / DataTable on one column. The column is to complex to sort in the database but I was hoping I could sort it like I would sort a generic list i.e. using a deligate. Is this possible or do I have to transfer it to a different data structure? Edit I can't get any of these answer to work for me, I think because I am using .Net 2

问题 There is already a similar question but it didn't seem to ask about the situation that the question implies. The user asked about custom classes in a list but his list object is of type string. I have a class Foo that has a list of Bars: public class Foo : FooBase { public List<Bar> bars {get; set;} public Foo() {} } public class Bar { public byte Id { get; set; } public byte Status { get; set; } public byte Type { get; set; } public Bar(){} } I instantiate Foo using reflection via Activator
