There’s no such thing as an empty char. The closest you can get is ‘\0′, the Unicode “null” character. Given that you can embed that within string literals or express it on its own very easily, why would you want a separate field for it? Equally, the “it’s easy to confuse “” and ” “” … Read more
Check if you are referencing an assembly which in turn referencing an old version of unity. For example let’s say you have an assembly called ServiceLocator.dll which needs an old version of Unity assembly, now when you reference the ServiceLocator you should provide it with the old version of Unity, and that makes the problem. … Read more
If the type implements IDisposable, it automatically disposes that type. Given: public class SomeDisposableType : IDisposable { …implmentation details… } These are equivalent: SomeDisposableType t = new SomeDisposableType(); try { OperateOnType(t); } finally { if (t != null) { ((IDisposable)t).Dispose(); } } using (SomeDisposableType u = new SomeDisposableType()) { OperateOnType(u); } The second is easier … Read more
Try using the \t character in your strings
It’s now possible to control which folder the packages are installed into. http://nuget.codeplex.com/workitem/215 Edit: See Phil Haack’s comment on Dec 10 2010 at 11:45 PM (in the work item/the link above). The support is partially implemented in 1.0, but is not documented. According to @dfowler: Add a nuget.config file next to the solution with this: … Read more
Some of the those leaving comments on other answers have noted that setting System.Net.ServicePointManager.SecurityProtocol to specific values means that your app won’t be able to take advantage of future TLS versions that may become the default values in future updates to .NET. Instead of specifying a fixed list of protocols, do the following: For .NET … Read more
It is whatever member of the enumeration represents the value 0. Specifically, from the documentation: The default value of an enum E is the value produced by the expression (E)0. As an example, take the following enum: enum E { Foo, Bar, Baz, Quux } Without overriding the default values, printing default(E) returns Foo since … Read more
Seems like string.Replace should have an overload that takes a StringComparison argument. Since it doesn’t, you could try something like this: public static string ReplaceString(string str, string oldValue, string newValue, StringComparison comparison) { StringBuilder sb = new StringBuilder(); int previousIndex = 0; int index = str.IndexOf(oldValue, comparison); while (index != -1) { sb.Append(str.Substring(previousIndex, index – … Read more
As stated, if you want to get 4 as the result, you can do like this: var nonintersect = array2.Except(array1); If you want the real non-intersection (also both 1 and 4), then this should do the trick: var nonintersect = array1.Except(array2).Union( array2.Except(array1)); This will not be the most performant solution, but for small lists it … Read more
Given an array you can use the Array.ConvertAll method: int[] myInts = Array.ConvertAll(arr, s => int.Parse(s)); Thanks to Marc Gravell for pointing out that the lambda can be omitted, yielding a shorter version shown below: int[] myInts = Array.ConvertAll(arr, int.Parse); A LINQ solution is similar, except you would need the extra ToArray call to get … Read more
