问题 I followed the tutorial here to auto-generate my POCO classes from an existing MySQL database. The generated POCO classes worked as expected for all of my MySQL table objects. The database also has a fairly complex, legacy MySQL view that references 8 tables using both INNER and LEFT OUTER joins. The view itself is fine and there's no issue when tested in MySQL workbench. However, when I tried to select a few records using the auto-generated POCO class for the view, the operation timed out

问题 Microsoft has Web Services Enhancements (WSE) 3.0 for .NET. The assembly is Micresoft.Web.Service3.dll. What's the replacement for this in .NET 4.0? 回答1: WSE 3.0 was the last version of WSE. In later .Net framework versions, WSE was superseded by WCF (Windows Communications Foundation). There is info on how to migrate from WSE to WCF here. WCF support for WS-* specifications is detailed here. 来源： https://stackoverflow.com/questions/3907157/whats-assembly-for-microsoft-web-service3-of-net-2-0

问题 I have this problem: The Vehicle type derives from the EntityObject type which has the property "ID". I think i get why L2S can't translate this into SQL- it does not know that the WHERE clause should include WHERE VehicleId == value . VehicleId btw is the PK on the table, whereas the property in the object model, as above, is "ID". Can I even win on this with an Expression tree? Because it seems easy enough to create an Expression to pass to the SingleOrDefault method but will L2S still fail

问题 I have created a c# web page which will be listening for POST data from a service. I've seen that I may need to use Request.GetBufferlessInputStream() which will read in the page data. I will then process this data further in my code. However, I cannot get the post data! I have found that I need to use Stream httpStream = Request.GetBufferlessInputStream(); Response.Write(httpStream.ToString()); but I am not sure how to then read that. I have tried reading from 0 to the end, but get only

问题 I'm trying to pull the DOM Snapshot Data (equivalent to doing an Inspect Element in Chrome) using C#. Here is my code: string url = "http://someurl"; HtmlDocument htmlDoc = new HtmlDocument(); htmlDoc.Load(new WebClient().OpenRead(url)); this.html = htmlDoc; The issue is that it is just pulling the source, not the DOM snapshot. How can I pull the DOM snapshot in C#? 来源： https://stackoverflow.com/questions/13939532/webclient-pull-dom-snapshot-data-vs-source

问题 I'm making a winforms C# project with .NET 4. I want to display a tooltip when the mouse hovers over a button or a textbox or whatever. Right now it displays almost as soon as the mouse stops moving. I don't like this. I want it to have more of a delay. Is there any way I can set a mousehover event delay time that is the same for all installed users? I suppose I could start a timer, and then cancel the timer when the mouse moves again but there's got to be a better way by golly! 回答1: Try this

问题 This is a follow-up to this question. Only bother reading it if you're interested in the back-story. In short, I am using reflection to load a set of generic types from an assembly. The assembly is loaded at run time. I have a second assembly referenced both by my current project and the assembly I'm loading which contains the interfaces: IJob IJobWrapper(Of IJob) The Assembly I'm loading (Call it Jobs.dll ) contains a JobWrapper(Of IJob) - which implements the IJobWrapper interface. Jobs.dll
