If you are starting with something that has a .Length or .Count (such as ICollection<T>, IList<T>, List<T>, etc) – then this will be the fastest option, since it doesn’t need to go through the GetEnumerator()/MoveNext()/Dispose() sequence required by Any() to check for a non-empty IEnumerable<T> sequence. For just IEnumerable<T>, then Any() will generally be quicker, … Read more
It is rare, in reality, that you would want to use an array. Definitely use a List<T> any time you want to add/remove data, since resizing arrays is expensive. If you know the data is fixed length, and you want to micro-optimise for some very specific reason (after benchmarking), then an array may be useful. … Read more
You can use the Assembly.GetManifestResourceStream Method: Add the following usings using System.IO; using System.Reflection; Set property of relevant file: Parameter Build Action with value Embedded Resource Use the following code var assembly = Assembly.GetExecutingAssembly(); var resourceName = “MyCompany.MyProduct.MyFile.txt”; using (Stream stream = assembly.GetManifestResourceStream(resourceName)) using (StreamReader reader = new StreamReader(stream)) { string result = reader.ReadToEnd(); } … Read more
In .NET, there are two categories of types, reference types and value types. Structs are value types and classes are reference types. The general difference is that a reference type lives on the heap, and a value type lives inline, that is, wherever it is your variable or field is defined. A variable containing a … Read more
LINQ to SQL only supports 1 to 1 mapping of database tables, views, sprocs and functions available in Microsoft SQL Server. It’s a great API to use for quick data access construction to relatively well designed SQL Server databases. LINQ2SQL was first released with C# 3.0 and .Net Framework 3.5. LINQ to Entities (ADO.Net Entity … Read more
AssemblyVersion Where other assemblies that reference your assembly will look. If this number changes, other assemblies must update their references to your assembly! Only update this version if it breaks backward compatibility. The AssemblyVersion is required. I use the format: major.minor (and major for very stable codebases). This would result in: [assembly: AssemblyVersion(“1.3”)] If you’re … Read more
When should we use one over the other? The decision is a trade-off between compatibility and API access. Use a .NET Standard library when you want to increase the number of applications that will be compatible with your library, and you are okay with a decrease in the .NET API surface area your library can … Read more
Html.Partial returns a String. Html.RenderPartial calls Write internally and returns void. The basic usage is: // Razor syntax @Html.Partial(“ViewName”) @{ Html.RenderPartial(“ViewName”); } // WebView syntax <%: Html.Partial(“ViewName”) %> <% Html.RenderPartial(“ViewName”); %> In the snippet above, both calls will yield the same result. While one can store the output of Html.Partial in a variable or return … Read more
I usually go with something like the implementation given in Josh Bloch’s fabulous Effective Java. It’s fast and creates a pretty good hash which is unlikely to cause collisions. Pick two different prime numbers, e.g. 17 and 23, and do: public override int GetHashCode() { unchecked // Overflow is fine, just wrap { int hash … Read more
float and double are floating binary point types (float is 32-bit; double is 64-bit). In other words, they represent a number like this: 10001.10010110011 The binary number and the location of the binary point are both encoded within the value. decimal is a floating decimal point type. In other words, they represent a number like … Read more
