I find the latter’s “minimum-to-maximum” format a lot clearer than Range‘s “minimum-count” style for this purpose. Also, I don’t think it’s really a good practice to make a change like this from the norm that is not faster, not shorter, not more familiar, and not obviously clearer. That said, I’m not against the idea in … Read more
Try the following: public static Stream ToStream(this Image image, ImageFormat format) { var stream = new System.IO.MemoryStream(); image.Save(stream, format); stream.Position = 0; return stream; } Then you can use the following: var stream = myImage.ToStream(ImageFormat.Gif); Replace GIF with whatever format is appropriate for your scenario.
var names = new Dictionary<int, string> { { 1, “Adam” }, { 2, “Bart” }, { 3, “Charlie” } };
Anonymous types are just regular types that are implicitly declared. They have little to do with dynamic. Now, if you were to use an ExpandoObject and reference it through a dynamic variable, you could add or remove fields on the fly. edit Sure you can: just cast it to IDictionary<string, object>. Then you can use … Read more
Your example is not an empty sequence, it’s a sequence with one element. To create an empty sequence of strings you can do var sequence = Enumerable.Empty<string>(); EDIT OP clarified they were looking to create a single value. In that case var sequence = Enumerable.Repeat(“abc”,1);
You can use: Enum.IsDefined(typeof(Age), youragevariable)
A lambda expression can either be converted to a delegate type or an expression tree – but it has to know which delegate type. Just knowing the signature isn’t enough. For instance, suppose I have: public delegate void Action1(); public delegate void Action2(); … Delegate x = () => Console.WriteLine(“hi”); What would you expect the … Read more
No, this seems perfectly reasonable. There is a List<T>.AddRange() method that basically does just this, but requires your collection to be a concrete List<T>.
Fields and properties look the same, but they are not. Properties are methods and as such there are certain things that are not supported for properties, and some things that may happen with properties but never in the case of fields. Here’s a list of differences: Fields can be used as input to out/ref arguments. … Read more
The really tricky part here was killing the long running task through passing the executor thread from the Action back to a place where it could be aborted. I accomplished this with the use of a wrapped delegate that passes out the thread to kill into a local variable in the method that created the … Read more
