Presumably the “problem” is that it’s just logging that it’s returning a task – and you want the value within that task? Assuming that’s the case, you still have to return the task to the caller, immediately – without waiting for it to complete. If you break that, you’re fundamentally messing things up. However, before … Read more
Use Class.getConstructor() and call Constructor.newInstance() on that. For example if this is your constructor on class Foo: public Foo(String bar, int baz) { } You’d have to do something like this: Constructor c = Class.forName(“Foo”).getConstructor(String.class, Integer.TYPE); Foo foo = (Foo) c.newInstance(“example”, 34); You’ll have to know what arguments need to be passed to the constructor. … Read more
You haven’t declared any properties – you’ve declared fields. Here’s similar code with properties: public class DocumentA { public string AgencyNumber { get; set; } public bool Description { get; set; } public bool Establishment { get; set; } public DocumentA() { AgencyNumber = “”; } } I would strongly advise you to use properties … Read more
Create your own delegate type: delegate void MyAction(ref DataRow dataRow, double doubleValue); And use MyAction in place of Action<ref DataRow, Double> — which, as you’ve noted, doesn’t compile.
I see you already accepted an answer, but honestly, that answer isn’t going to be enough to do this reliably if you just combine what’s in there with what you already wrote. It’s on the right track, but your code will only work for generic types with exactly one generic parameter, and it will only … Read more
Here’s the solution that I’ve arrived at. It doesn’t get the Types before traversing the data, and so doesn’t know before hand the type of each value before pulling the values out through Scan(), but the point really is to not have to know the types before hand. The trick was to create 2 slices, … Read more
Doclet class: public class ExtractCommentsDoclet { public static boolean start(RootDoc root) throws IOException { for (ClassDoc c : root.classes()) { print(c.qualifiedName(), c.commentText()); for (FieldDoc f : c.fields(false)) { print(f.qualifiedName(), f.commentText()); } for (MethodDoc m : c.methods(false)) { print(m.qualifiedName(), m.commentText()); if (m.commentText() != null && m.commentText().length() > 0) { for (ParamTag p : m.paramTags()) print(m.qualifiedName() + … Read more
In one product I’m working on we use it a lot, but Reflection is a complex, slow beast. Don’t go looking for places to use it just because it sounds fun or interesting. You’ll use it when you run into a problem that can’t be solved in any other way (dynamically loading assemblies for plug … Read more
With C#6.0 you can get it by nameof(ClassName.IntProperty)
This problem can be broken into two pieces, how you represent the data type and how you compose them together. Data types The styles you listed use only 2 styles of data types, the “normal” style and the continuation passing style. They differ in which objects are chosen as the primitives of the language. In … Read more
