Linq based generic alternate to Predicate<T>?

I have an interface called ICatalog as shown below where each ICatalog has a name and a method that will return items based on a Predicate<Item> function. public interface ICatalog { string Name { get; } IEnumerable<Item> GetItems(Predicate<Item> predicate); } A specific implementation of a catalog may be linked to catalogs ...

T-SQL generated from LINQ to SQL is missing a where clause

I have a DataContext object, called "CodeLookupAccessDataContext", that was generated through the Visual Studio LINQ to SQL class wizard. I extended the functionality of this object such that it exposes some methods to return results of LINQ to SQL queries. Here are the methods I have defined: public List<CompositeSIDMap> lookupCompos...

.NET Form_load priority

So, the problem is such as this: I have a method that does stuff and updates a progress bar. If I call the method after the form is fully loaded (i.e.: by assigning it to a button on the form) everything works fine. The problem is that I need the method to start working as soon as the form loads, by itself, so I would place it in the For...

Class/Model Level Validation (as opposed to Property Level)? (ASP.NET MVC 2.0)

Basically, what the title says. I have several properties that combine together to really make one logical answer, and i would like to run a server-side validation code (that i write) which take these multiple fields into account and hook up to only one validation output/error message that users see on the webpage. I looked at scott gut...

Point in polygon OR point on polygon using LINQ

As noted in an earlier question, How to Zip enumerable with itself, I am working on some math algorithms based on lists of points. I am currently working on point in polygon. I have the code for how to do that and have found several good references here on SO, such as this link Hit test. So, I can figure out whether or not a point is ...

WCF Best Practice for "Overloaded" methods

What is the best practice for emulating overloaded methods over WCF? Typically I might write an interface like this interface IInterface { MyType ReadMyType(int id); IEnumerable<MyType> ReadMyType(String name); IEnumerable<MyType> ReadMyType(String name, int maxResults); } What would this interface look like after yo...

Windows/.NET Load Distribution & Balancing

Hi all, Is there a vetted Windows-friendly, or even .NET-native, load-distributing/load-balancing utility out there along the lines of HA Proxy? We have a .NET stack product, and the one piece that we step out of the stack is for load-balancing. We need something with configurable rules for distribution -- perhaps subdomain-driven -- t...

Good implementation of weak dictionary in .Net

Where can I find good implementation of IDictionary which uses weak references inside? Dictionary should be holding only weak references to values and eventually clean up itself of dead references. Or should I just write it myself? ...

C# - System.StackOverflowException with Lambda

Under what situations would this code error out with System.StackOverflowException? Accounts.Sort((x, y) => string.Compare(x.AccountId, y.AccountId)); Update: the property is written as: public string AccountId { get { return _accountId; } set { _accountId = value; } } Nothing special going on at all. ...

Why is there no Sum() extension for IEnumerable<uint>

It seems that Sum is not defined for IEnumerable<uint> (and other unsigned integers, for that matter) var s = new int[] { 1, 2, 3 }; s.Sum(); //works fine var us = new uint[] { 1, 2, 3 }; us.Sum(); //missing method I would like to know: Have I done something fundamentally wrong/misunderstood the situation? What design decisions mig...

Tests run in Gallio / MbUnit fail; unable to load Castle DynamicProxy

I have a .NET 3.5 assembly covered by around 4000 MbUnit tests. I hve been running these using the mbunit.cons.exe program with no trouble. Now I am trying to switch to Gallio (mbunit.cons.exe started blowing up with an 'out of memory' exception when producing the XML report). When running the tests in Icarus, most of them fail with th...

Is there a workaround for Linux mono's refusal to acknowledge that I have resized the columns of my VirtualMode ListView?

When I resize a column, it does not redraw the data with the updated alignment. I've tried Invalidating, Refreshing, and a few other things. Nothing has worked. Does anyone know a workaround? I have not tried this in mono for Windows. To see what I mean, drop this control on a form, and run it in mono for Linux: using System; using...

Faster way to clone.

I am trying to optimize a piece of code that clones an object: #region ICloneable public object Clone() { MemoryStream buffer = new MemoryStream(); BinaryFormatter formatter = new BinaryFormatter(); formatter.Serialize(buffer, this); // takes 3.2 seconds buffer.Position = 0; return formatter.Deserialize(buffer);...

How to dynamically change fields in an .NET ORM

I'm working in ASP.NET in an application where often users want to add fields or change field names. I'd like to be able to have an xml schema in place that is parsed and a dynamic object model created from it that can be accessed throughout the application. My initial reaction is that this is not realistic. I think there is flexibilit...

does class/object models have a out-of-the-box equivalent to a database foreign key constraint

Hi, Does does class/object models have a out-of-the-box equivalent to a database foreign key constraint? Assume the language is C# please. That is say Class A has a field that references Class B and vica-versa. If I have Object A & B (instantiated from these classes) what happens if I delete Object B? Does it auto-delete or throw a ...
