When writing a help document, the intercepted pictureif there is a mouse pointer shape, it will look more intuitive and friendly. Next, let’s talk about how to include the mouse pointer shape in the screenshot.
Add structure CURSORINFO:
[StructLayout(LayoutKind.Sequential)] struct CURSORINFO { public int cbSize; public int flags; public IntPtr hCursor; public Point ptScreenPos; }
Declare API:
[DllImport("user32.dll")] static extern bool GetCursorInfo(out CURSORINFO pci);
Define enumeration value:
private const int CURSOR_SHOWING = 0x00000001;
Add method:
/// <summary> /// 将鼠标指针形状绘制到屏幕截图上 /// </summary> /// <param name="g"></param> private void DrawCursorImageToScreenImage(ref Graphics g) { if (!this.IsCutCursor) { return; } CURSORINFO vCurosrInfo; vCurosrInfo.cbSize = Marshal.SizeOf(typeof(CURSORINFO)); GetCursorInfo(out vCurosrInfo); if ((vCurosrInfo.flags & CURSOR_SHOWING) != CURSOR_SHOWING) return; Cursor vCursor = new Cursor(vCurosrInfo.hCursor); Rectangle vRectangle = new Rectangle(new Point(vCurosrInfo.ptScreenPos.X - vCursor.HotSpot.X, vCurosrInfo.ptScreenPos.Y - vCursor.HotSpot.Y), vCursor.Size); vCursor.Draw(g, vRectangle); }
Add method call:
OK, let’s take a screenshot again!

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.

C#.NET interview questions and answers include basic knowledge, core concepts, and advanced usage. 1) Basic knowledge: C# is an object-oriented language developed by Microsoft and is mainly used in the .NET framework. 2) Core concepts: Delegation and events allow dynamic binding methods, and LINQ provides powerful query functions. 3) Advanced usage: Asynchronous programming improves responsiveness, and expression trees are used for dynamic code construction.
