问题 I have populated a DataTable from a stored procedure in an older web application written in C# under .NET 2.0 / Visual Studio 2005. I'm trying to populate a List with the values in the DataTable, but I keep running up against a couple issues. My conversion process looks like this: List<int> SpecialVendorList = new List<int>(); foreach (DataRow datarow in GetAllSpecialVendors().Rows) { //Loop through each row foreach (DataColumn column in GetAllSpecialVendors().Columns) { SpecialVendorList.Add

问题 I got a function which wants to send 2 INT parameters back to where it has been called, but not sure what would be the best option, a Dictionary ? or a List or an Array EDITED I am using .Net framework 2 回答1: I assume you mean return 2 values to the caller. If so: return a Tuple<T1, T2> return your own custom type which stores the desired values, like MyOperationResult use out parameters: http://msdn.microsoft.com/en-us/library/t3c3bfhx(v=vs.80).aspx return a collection It depends on what is

问题 1) user A goes to the site, creates an account, and logs in 2) user b goes to the site. Rather than having to log in, user b enters as though user b is user a. User b gets access to all of user a's data and can brows the site as user a. Note: user b does not log in. User b just hits the site, and the site returns as if user b is already logged in as user a. Note 2: user a and user b are on distinct computers. Also, static variables are not involved in the code. Setup: IIS 6 .Net 2.0

问题 I'm trying to draw a series of connected segments, but the curved segments seem to produce an artifact, whereby the outer side of the curve is not smooth at all, but very jagged. This is part of a GIS program I am making. For these lines, the line itself needs to be quite wide, as this represents the range of data that can be collected on this line for the GIS data. There also has to be an area directly under the line where no data is collected. This also can be wide, but not as wide as the

问题 I'm working on a project that is stuck on .NET 2.0 (though we can use C# 3.0), and I'd like to use the facilities of a nice container (e.g. StructureMap). Does anyone know what the latest version of StructureMap that supports .NET 2.0 is? Or if there is any other container (preferably not Unity, but I could be convinced) that supports .NET 2.0? Thanks in advance. 回答1: That would be StructureMap-2.0. The next release which is StructureMap.2.4.9 already depends on the System.Core assembly which

问题 .NET 2 Actually there are methods to XML serialize a List<T> . What if I have an object that has a public LinkedList<T> member? Without creating a public duplicate as List<T> from LinkedList<T> . Maybe a way to control the Xml serialization like binary (OnSerializing, OnDeserializing). Will be impossible to XML serialize a object with a public LinkedList<T> member? EDIT: An test example to fix with IXmlSerializable using System.Xml.Serialization; public class Foo : IXmlSerializable { private

问题 I have been developing an ASP.NET application on Windows XP Professional. While promoting to production I have only now found out that the server is 64 bit. I installed Oracle Client 32 bit on the server and cannot connect to Oracle. I am using the Microsoft Provider for Oracle, and my question is, how do I get an ASP.NET application compiled on a 32 bit machine to connect to Oracle on a Windows Server 2003 64 bit machine? EDIT: In response to a comment on my original question, the error I am

问题 I have written the following code in .NET 2.0 foreach(Item i in millonItemsIterator) { ItemThreadManager m = new ItemThreadManager(i); System.Threading.Thread t = new System.Threading.Thread(m.Process); t.Start() } SendCompletionEmail(); public class ItemThreadManager { private static Semaphore s = new Semaphore(20, 20); private Item item = null; public ItemThreadManager(Item i) { item = i; } public void Process() { s.WaitOne(); // do something with item. s.Release(); } } My intention behind

问题 A LinkedList can't be serialized using XmlSerializer. Now, how to however save/retrieve data from a serialized objet LinkedList. Should I implement custom serialization? What I tried to do: using System.Xml.Serialization; [Serializable()] public class TestClass { private int _Id; private string _Name; private int _Age; private LinkedList<int> _linkedList = new LinkedList<int>(); public string Name { get { return _Name; } set { _Name = value; } } public string Age { get { return _Age; } set {
