问题 I have not found yet a file-rename-function in .NET for C#, so I'm a bit confused how I would rename a file. I use the command prompt with Process.Start, but this isn't really professional and a black DOS window is popping up each time. Yes, I know there is something in the Visual Basic namespace, but this is not my intention to add the "visual-basic.dll" to my project. I found some examples which "move" the file to rename it. It is a quite painful method and a shoddy workaround for things.

问题 I'm trying the find the best way to send a GridView or DataTable in an email. Page Behind Code: protected void Page_Load(object sender, EventArgs e) { DataTable s1 = Sql.specificReportData(Convert.ToInt32(Session["userID"])); this.gv.DataSource = s1.DefaultView; this.gv.DataBind(); } This generates and binds the data successfully, but if I try and add the contents of gv to a HTML encoded email then the gv part of the email is blank. Do I need to alter the GridView so it's HTML compliant? I

问题 I already asked how to enum 32bit process modules from a 64bit process here. And the answer was EnumProcessModulesEx. All works fine on Windows 7 x64, but what about Windows XP x64? It seems that this api is supported on Vista and up. So what's the way to do it there? 回答1: CreateToolHelp32Snapshot will do it. 回答2: Probably something like this. Wrote it in notepad so might be wrong. But you get the idea. HANDLE hSnapshot = CreateToolhelp32Snapshot( TH32CS_SNAPMODULE, dwPID ); MODULEENTRY32

问题 It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form.

问题 I have some .Net 3.5 code that uses the XDocument class. Can you suggest a quick and dirty way to get this code running in .Net 2.0? public static HaarClassifierCascade Parse(XDocument xDoc) { HaarClassifierCascade cascade = null; XElement stages_fn; XElement seq_fn = null; /* sequence */ XElement fn; int n; int i = 0, j = 0, k = 0, l = 0; int parent, next; stages_fn = xDoc.Descendants(stageId).First(); n = stages_fn.Elements().Count(); cascade = new HaarClassifierCascade(n); seq_fn = xDoc

问题 This code is not setting right value to the combobox. This is because, those are from different contexts. In addition, in my actual problem, neither overloading == in nor overriding Equals() in MyClass is working as well. Any alternative way? How to solve this problem? MyClass.cs public class MyClass { public int ID { get; set; } public string Name { get; set; } public MyClass(int id, string name) { ID = id; Name = name; } public static List<MyClass> Get() { return new List<MyClass> { new

问题 I have some C# code that is giving a StackOverflowException when running under IIS7 but when it is run under Cassini in VS2008 then the code runs fine. Is this a known issue whereby Cassini handles these kinds of exceptions differently? 回答1: The IIS runtime uses a different stack size for threads. IIRC it is 256 KB as opposed to the standard 1 MB you get when running on the standard .NET runtime, which is the one VS uses. In other words, you may have code that runs fine under the regular .NET
