Shortcuts are widely used on Win32. For example, after a certain software is installed, some shortcuts will be created
in a specific directory. So on .NET, I have not found any managed classes that can operate shortcuts. So We
using System; using System.IO; using System.Runtime.InteropServices; class Program { static void Main(string[] args) { CreateShortCut( // 创建快捷方式 @"C:\Users\windo\Desktop\ican.lnk", @"%HOMEDRIVE%/Program Files\Internet Explorer\IEXPLORE.EXE", AppDomain.CurrentDomain.BaseDirectory, @"%HOMEDRIVE%/Program Files\Internet Explorer\IEXPLORE.EXE, 0", "CTRL+ALT+Z" ); } public static readonly Guid CLSID_WshShell = new Guid("72C24DD5-D70A-438B-8A42-98424B88AFB8"); public static string GetShortCutTarget(string lnk) // 取快捷方式目标 { if (lnk != null && File.Exists(lnk)) { dynamic objWshShell = null, objShortcut = null; try { objWshShell = Activator.CreateInstance(Type.GetTypeFromCLSID(CLSID_WshShell)); objShortcut = objWshShell.CreateShortcut(lnk); return objShortcut.TargetPath; } finally { Marshal.ReleaseComObject(objShortcut); Marshal.ReleaseComObject(objWshShell); } } return string.Empty; } public static bool CreateShortCut(string lnkFileName, string targetPath, string arguments, string remark, string workingDirectory, string iconLocation, string hotKey ) { if (lnkFileName != null && lnkFileName.Length > 0) { dynamic objWshShell = null, objShortcut = null; try { objWshShell = Activator.CreateInstance(Type.GetTypeFromCLSID(CLSID_WshShell)); objShortcut = objWshShell.CreateShortcut(lnkFileName); objShortcut.WindowStyle = 1; objShortcut.Hotkey = hotKey; // 热键 objShortcut.TargetPath = targetPath; // 目标文件 objShortcut.Arguments = arguments; // 参数 objShortcut.Description = remark; // 备注 objShortcut.WorkingDirectory = workingDirectory; // 起始位置 objShortcut.IconLocation = iconLocation; // 图标位置 objShortcut.Save(); return true; } finally { Marshal.ReleaseComObject(objShortcut); Marshal.ReleaseComObject(objWshShell); } } return false; } }

C#.NET is still important because it provides powerful tools and libraries that support multiple application development. 1) C# combines .NET framework to make development efficient and convenient. 2) C#'s type safety and garbage collection mechanism enhance its advantages. 3) .NET provides a cross-platform running environment and rich APIs, improving development flexibility.

C# and .NET adapt to the needs of emerging technologies through continuous updates and optimizations. 1) C# 9.0 and .NET5 introduce record type and performance optimization. 2) .NETCore enhances cloud native and containerized support. 3) ASP.NETCore integrates with modern web technologies. 4) ML.NET supports machine learning and artificial intelligence. 5) Asynchronous programming and best practices improve performance.

The programming process of C# in .NET includes the following steps: 1) writing C# code, 2) compiling into an intermediate language (IL), and 3) executing by the .NET runtime (CLR). The advantages of C# in .NET are its modern syntax, powerful type system and tight integration with the .NET framework, suitable for various development scenarios from desktop applications to web services.

C# is a modern, object-oriented programming language developed by Microsoft and as part of the .NET framework. 1.C# supports object-oriented programming (OOP), including encapsulation, inheritance and polymorphism. 2. Asynchronous programming in C# is implemented through async and await keywords to improve application responsiveness. 3. Use LINQ to process data collections concisely. 4. Common errors include null reference exceptions and index out-of-range exceptions. Debugging skills include using a debugger and exception handling. 5. Performance optimization includes using StringBuilder and avoiding unnecessary packing and unboxing.

Testing strategies for C#.NET applications include unit testing, integration testing, and end-to-end testing. 1. Unit testing ensures that the minimum unit of the code works independently, using the MSTest, NUnit or xUnit framework. 2. Integrated tests verify the functions of multiple units combined, commonly used simulated data and external services. 3. End-to-end testing simulates the user's complete operation process, and Selenium is usually used for automated testing.

Interview with C# senior developer requires mastering core knowledge such as asynchronous programming, LINQ, and internal working principles of .NET frameworks. 1. Asynchronous programming simplifies operations through async and await to improve application responsiveness. 2.LINQ operates data in SQL style and pay attention to performance. 3. The CLR of the NET framework manages memory, and garbage collection needs to be used with caution.
