First, this is not MVC, WebForms only.. I'm using routing to keep my site backwards compatible for our clients, while make my project organized. I'm also thinking of moving our encrypted query string to a more friendly url. How this works is our clients have to bookmark a huge encrypted url to prevent them from guessing our other clients by changing an id around. But instead of having this huge url, wanted to add a route like LoginClientName.aspx for each client and have the encrypted query string hard coded or maybe in database. But don't see a way to add a query to the MapPageRoute.. Was

I'm working on an app that uses an UNC path to access remote files in the same LAN. The problem is that when access is attempted it throws an exception related to Windows credentials. Is there a way to add credentials to my UNC path? Thank you It might be useful for you to use the NetUseAdd function from the windows api http://msdn.microsoft.com/en-us/library/windows/desktop/aa370645(v=vs.85).aspx . It allows you to access a directory through its UNC path. Derek Risling Looks like Win32 APIs are the most common way to handle this. Check out this SO post Accessing a Shared File (UNC) From a

System.Collections.IStructuralEquatable and System.Collections.IStructuralComparable were added in .NET 4, but why aren't they generic, like IEquatable<T> and IComparable<T> ? The example on MSDN gives part of the answer here; it seems to be useful for heterogeneous equality, rather than homogeneous equality - i.e. for testing whether two objects (/values) of potentially different types should be considered equal. In such scenarios, it is extremely likely that the calling code is dealing with object (to represent heterogeneous data). And generic methods don't play nicely then. 来源： https:/

I have been using the following code for months (without problem) in a .NET 2.0/3.5 environment: string server="192.168.1.3"; IPHostEntry ipe = System.Net.Dns.GetHostEntry(server); IPAddress ipa = ipe.AddressList[0]; IPEndPoint ipep = new IPEndPoint(ipa, (int)UdpServices.Domain); Here, server is hardcoded to an IP address, but in my application it could potentially be something like "server.test.com". When converting my project to .NET 4.0, this code stopped working when directly passing an IP address (still works with a hostname). It crashes with this exception: System.Net.Sockets

A common practice to avoid race conditions (in multi-threaded apps) when triggering events is this: EventHandler<EventArgs> temp = SomeEvent; if (temp != null) temp(e); "Remember that delegates are immutable and this is why this technique works in theory. However, what a lot of developers don't realize is that this code could be optimized by the compiler to remove the local temp variable entirely. If this happens, this version of the code is identical to the first version, so a NullReferenceException is still possible." The problem (according to the book) is that "this code could be optimized
