This sample shows how to read and write a string to a MemoryStream. Imports System.IO Module Module1 Sub Main() ‘ We don’t need to dispose any of the MemoryStream ‘ because it is a managed object. However, just for ‘ good practice, we’ll close the MemoryStream. Using ms As New MemoryStream Dim sw As New … Read more
Unless you simply need an array to meet other constraints you should use ToList. In the majority of scenarios ToArray will allocate more memory than ToList. Both use arrays for storage, but ToList has a more flexible constraint. It needs the array to be at least as large as the number of elements in the … Read more
Commons Lang has it. Or you could throw an UnsupportedOperationException.
Internal classes need to be tested and there is an assembly attribute: using System.Runtime.CompilerServices; [assembly:InternalsVisibleTo(“MyTests”)] Add this to the project info file, e.g. Properties\AssemblyInfo.cs, for the project under test. In this case “MyTests” is the test project.
Use replace with Environment.NewLine myString = myString.Replace(System.Environment.NewLine, “replacement text”); //add a line terminating ; As mentioned in other posts, if the string comes from another environment (OS) then you’d need to replace that particular environments implementation of new line control characters.
Try this: using System.Diagnostics; // Get call stack StackTrace stackTrace = new StackTrace(); // Get calling method name Console.WriteLine(stackTrace.GetFrame(1).GetMethod().Name); one-liner: (new System.Diagnostics.StackTrace()).GetFrame(1).GetMethod().Name It is from Get Calling Method using Reflection [C#].
Much easier private static void CopyFilesRecursively(string sourcePath, string targetPath) { //Now Create all of the directories foreach (string dirPath in Directory.GetDirectories(sourcePath, “*”, SearchOption.AllDirectories)) { Directory.CreateDirectory(dirPath.Replace(sourcePath, targetPath)); } //Copy all the files & Replaces any files with the same name foreach (string newPath in Directory.GetFiles(sourcePath, “*.*”,SearchOption.AllDirectories)) { File.Copy(newPath, newPath.Replace(sourcePath, targetPath), true); } }
Yes, but you need to declare it readonly instead of const: public static readonly string[] Titles = { “German”, “Spanish”, “Corrects”, “Wrongs” }; The reason is that const can only be applied to a field whose value is known at compile-time. The array initializer you’ve shown is not a constant expression in C#, so it … Read more
While you can use a ForEach extension method, if you want to use just the framework you can do collection.Select(c => {c.PropertyToSet = value; return c;}).ToList(); The ToList is needed in order to evaluate the select immediately due to lazy evaluation.
If you’ve definitely got an absolute path, use Path.GetDirectoryName(path). If you might only get a relative name, use new FileInfo(path).Directory.FullName. Note that Path and FileInfo are both found in the namespace System.IO.
