Just cast the enum, e.g. int something = (int) Question.Role; The above will work for the vast majority of enums you see in the wild, as the default underlying type for an enum is int. However, as cecilphillip points out, enums can have different underlying types. If an enum is declared as a uint, long, … Read more
In C# 5 and earlier, to give auto implemented properties an initial value, you have to do it in a constructor. Since C# 6.0, you can specify initial value in-line. The syntax is: public int X { get; set; } = x; // C# 6 or higher DefaultValueAttribute is intended to be used by the … Read more
The Random class is used to create random numbers. (Pseudo-random that is of course.). Example: Random rnd = new Random(); int month = rnd.Next(1, 13); // creates a number between 1 and 12 int dice = rnd.Next(1, 7); // creates a number between 1 and 6 int card = rnd.Next(52); // creates a number between … Read more
There is actually a (subtle) difference between the two. Imagine you have the following code in File1.cs: // File1.cs using System; namespace Outer.Inner { class Foo { static void Bar() { double d = Math.PI; } } } Now imagine that someone adds another file (File2.cs) to the project that looks like this: // File2.cs … Read more
Contrary to the answers here, you DON’T need to worry about encoding if the bytes don’t need to be interpreted! Like you mentioned, your goal is, simply, to “get what bytes the string has been stored in”. (And, of course, to be able to re-construct the string from the bytes.) For those goals, I honestly … Read more
Catch System.Exception and switch on the types catch (Exception ex) { if (ex is FormatException || ex is OverflowException) { WebId = Guid.Empty; return; } throw; }
Whereas one approach is to implement the ICloneable interface (described here, so I won’t regurgitate), here’s a nice deep clone object copier I found on The Code Project a while ago and incorporated it into our code. As mentioned elsewhere, it requires your objects to be serializable. using System; using System.IO; using System.Runtime.Serialization; using System.Runtime.Serialization.Formatters.Binary; … Read more
C# language version history: These are the versions of C# known about at the time of this writing: C# 1.0 released with .NET 1.0 and VS2002 (January 2002) C# 1.2 (bizarrely enough); released with .NET 1.1 and VS2003 (April 2003). First version to call Dispose on IEnumerators which implemented IDisposable. A few other small features. … Read more
foreach(KeyValuePair<string, string> entry in myDictionary) { // do something with entry.Value or entry.Key }
You could use the String.IndexOf Method and pass StringComparison.OrdinalIgnoreCase as the type of search to use: string title = “STRING”; bool contains = title.IndexOf(“string”, StringComparison.OrdinalIgnoreCase) >= 0; Even better is defining a new extension method for string: public static class StringExtensions { public static bool Contains(this string source, string toCheck, StringComparison comp) { return source?.IndexOf(toCheck, … Read more
