There are two common approaches. First, you can pass System.Type This would be called like: int val = (int)GetColumnValue(columnName, typeof(int)); The other option would be to use generics: This has the advantage of avoiding the boxing and providing some type safety, and would be called like: int val = GetColumnValue<int>(columnName);
In C#, unlike VB.NET and Java, you can’t access static members with instance syntax. You should do: to refer to that property or remove the static modifier from Property1 (which is what you probably want to do). For a conceptual idea about what static is, see my other answer.
IEnumerable describes behavior, while List is an implementation of that behavior. When you use IEnumerable, you give the compiler a chance to defer work until later, possibly optimizing along the way. If you use ToList() you force the compiler to reify the results right away. Whenever I’m “stacking” LINQ expressions, I use IEnumerable, because by … Read more
Well you certainly can use a List<List<string>> where you’d then write: But why would you do that instead of building your own class to represent a track, with Track ID, Name, Artist, Album, Play Count and Skip Count properties? Then just have a List<Track>.
I am trying to read a *.csv-file. The *.csv-file consist of two columns separated by semicolon (“;“). I am able to read the *.csv-file using StreamReader and able to separate each line by using the Split() function. I want to store each column into a separate array and then display it. Is it possible to … Read more
I have spent the best part of two days “faffing” about with code samples and etc., trying to read a very large JSON file into an array in c# so I can later split it up into a 2d array for processing. The problem I was having was I could not find any examples of … Read more
Local variables aren’t initialized. You have to manually initialize them. Members are initialized, for example: But local variables are not: So your code must be: So the long and the short of it is, members are initialized, locals are not. That is why you get the compiler error.
Dan (the original poster) mentioned in a comment above that running Visual Stuio as admin solved this for him.
I assume those XAML namespace declarations are in the parent tag of your control? You can’t put comments inside of another tag. Other than that, the syntax you’re using is correct.
There are several ways to perform HTTP GET and POST requests: Method A: HttpClient (Preferred) Available in: .NET Framework 4.5+, .NET Standard 1.1+, .NET Core 1.0+ . It is currently the preferred approach, and is asynchronous and high performance. Use the built-in version in most cases, but for very old platforms there is a NuGet package. Setup It is recommended to instantiate one HttpClient for your application’s … Read more
