问题 I need to convert all attributes to nodes in an XML file, with the exception of attributes in the root node. I found a similar question here: xquery to convert attributes to tags, but I need to do the conversion in C#. I have also found a possible solution using XLS here: Convert attribute value into element. However, that solution essentially changes the node name to the attribute name and removes the attribute. I need to create new sibling nodes with the name and value of the attributes and

问题 I know there is another question asking the same thing, but it hasn't gotten any attention for months now: https://stackoverflow.com/questions/3786088/how-to-force-ajax-control-toolkit-scripts-loading-from-cdn I've upgraded my website to .NET4, and I'm now using the scriptManager's EnableCDN="true" tag. My Ajax scripts are being referenced from the Microsoft CDN just how I expected, but I can't seem to get my AjaxControlToolkit scripts to load from the CDN. Instead they all load locally

问题 .Net 4.0 is encoding single quotes when I am using Attributes.Add to add client side events to my asp.net objects. In the previous versions this didn't happen. for example : <asp:Image runat="server" ID="imgTest" ImageUrl="~/DateControl/cal.gif" /> imgTest.Attributes.Add("onmouseover", "alert('Hello')"); When I view the client side output, I am getting <img id="ctl00_MainContent_calFromTimeStamp1_imgTest" onmouseover="alert('Hello')" src="../DateControl/cal.gif" style="border-width:0px;" /> I

问题 I'm trying to write a bare-bones ultra-simple light-weight wrapper for the LibVLC DLL Library. I don't need access to much, just the ability to play pause and stop media files. I'm looking at the documentation and this other link I found that explains an older version of LibVLC, but it's outdated for the most recent version. I also tried LibVLC.Net but it too is outdated and I can't find what I'm looking for in the source code to match it to the functions I'm trying to export. I have the

问题 I got TLS 1.0 disabled. So we are trying to use TLS 1.2 in our .Net application which is using .Net Framework 4.0. I have added the code for this at the start System.Net.ServicePointManager.SecurityProtocol = (SecurityProtocolType)3072; It works perfectly on my local system. But i am not sure why its not working when I deploy the code on server (Windows Server 2008 R2). I checked everything. .Net framework is present on server. But still its giving the same issue on server only. Is there

问题 So let's say I have a type Car with two properties Speed and Color public class Car { public int Speed {get; set;} public string Color {get; set;} } Using LINQ I may find the minimum speed int minSpeed = collection.Min(em => em.Speed); so minSpeed will contain the value of speed of the car with the minimum speed in collection. But how can I do something similar to get the color of the car? Something like: string color = collection.Min(em => em.Speed).Select(x => x.Color); 回答1: Use MinBy. Car

问题 I have an ssl/tls server (nodejs) that acts as a proxy to postfix/sendmail to perform some pre-processing/data aquisition on outgoing mail. From C#, I can manually connect and authenticate with the following code: var sslStream = new SslStream(tcpClient.GetStream(), false, new RemoteCertificateValidationCallback(CertificateValidation), new LocalCertificateSelectionCallback(CertificateSelectionCallback)); string fn = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "cert.pem");

问题 The database contains Orders. Orders can be contained within a group of Orders. For every group of Orders it could contain 1 to many Orders. However, Orders could have a NULL value assigned GroupOrderId as previous Orders did not have the grouping concept. Only new Orders enforce the concept of being added to a group. The class structure to be populated in order to perform actions on each Order is public class OrdersGroup { public int? GroupOrderId { get; set; } public List<int> OrderIds {
