I feel that many classes (e.g. TcpClient , UdpClient , HttpListener ) would've been much easier to understand and use if they were

问题 I've got a web form with Password and Confirm Password text boxes. I've got a RegularExpressionValidator attached to the first one and CompareValidator to the second one. Now the problem is when i have something in the Password field and nothing in Confirm Password field it does not display an error that fields don't match. As soon as i put something in the Confirm Password field it shows the error. I also want to allow to leave both fields blank. I'm using .NET 2.0 What might it be? 回答1:

问题 I'm trying to create a script to compile an Windows Forms C# 2.0 project from the command line (I know, I know.. I'm reinventing the wheel.. again.. but if somebody knows the answer, I'd appreciate it). The project is a standard Windows Forms project that has some resources and references a couple external assemblies. Here is a list of the files: Program.cs // no need to expand on this on :) frmMain.cs // this is a typical C# windows forms file frmMain.designer.cs // .. and the designer code

问题 We have custom DLL's that are not included in our initial setup file. They are loaded at runtime. This process worked fine while using .NET 2.0, but we are getting the "The invoked member is not supported in a dynamic assembly" error message now that we are using .NET 4.0. try { assem = Assembly.LoadFrom(fi.FullName); //fi is FileSystemInfo } catch (FileLoadException) {} catch (BadImageFormatException) {} catch (System.Security.SecurityException) {} catch (ArgumentException) {} catch

问题 Please note that this is required for a C# .NET 2.0 project ( Linq not allowed ). I know very similar questions have been asked here and I have already produce some working code (see below) but still would like an advice as to how to make the algorithm faster given k and s conditions. This is what I've learnt so far: Dynamic programming is the most efficient way to finding ONE (not all) subsets. Please correct me if I am wrong. And is there a way of repeatedly calling the DP code to produce

问题 The question says it all. 回答1: An assembly in the GAC does not know about the private locations of your private assemblies. It is only aware about the GAC itself. So it can refer to the assemblies that are available in the GAC only 回答2: No - the GAC is the place where you place assemblies that you specifically want to be available globally. 来源： https://stackoverflow.com/questions/2624335/if-an-assembly-is-in-the-gac-do-all-assemblies-that-it-calls-have-to-be-in-the

问题 I am using datetimepicker to select only day and month, Year is irrelevant. How do I disable/restrict the year selection by user. or rather year shouldn't be shown when user tries to select the date 回答1: If you restrict the two dates that the user can choose between on the DateTimePicker as well as set a custom format for the picker itself, you can effectively have an all in one Up/Down control that selects date time. If year is not important, you can set the MinDate and MaxDate values to a

问题 I have array of nearly 1,000,000 records, each record has a field "filename". There are many records with exactly the same filename. My goal is to improve memory footprint by deduplicating string instances (filename instances, not records). .NET Framework 2.0 is a constraint. no LINQ here. I wrote a generic (and thread-safe) class for the deduplication: public class Deduplication<T> where T : class { private static Deduplication<T> _global = new Deduplication<T>(); public static Deduplication
