Jan 19, 2025 am 07:24 AMRead C/C data structure from byte array to C#
In C#, when receiving byte array data from a C/C structure, you need to convert the array into a compatible C# structure. The following methods provide an efficient conversion path.
Use Marshal.PtrToStructure
This method involves fixing a byte array and using Marshal.PtrToStructure to convert the bytes directly into a C# structure.
NewStuff ByteArrayToNewStuff(byte[] bytes) { GCHandle handle = GCHandle.Alloc(bytes, GCHandleType.Pinned); try { NewStuff stuff = (NewStuff)Marshal.PtrToStructure(handle.AddrOfPinnedObject(), typeof(NewStuff)); return stuff; } finally { handle.Free(); } }
Universal version
This generic version allows conversion of any struct type from a byte array:
T ByteArrayToStructure<T>(byte[] bytes) where T : struct { GCHandle handle = GCHandle.Alloc(bytes, GCHandleType.Pinned); try { return (T)Marshal.PtrToStructure(handle.AddrOfPinnedObject(), typeof(T)); } finally { handle.Free(); } }
Simplified version
For simple applications, use unsafe fixed arrays:
unsafe T ByteArrayToStructure<T>(byte[] bytes) where T : struct { fixed (byte* ptr = &bytes[0]) { return (T)Marshal.PtrToStructure((IntPtr)ptr, typeof(T)); } }
Comparison of BinaryReader and Marshal.PtrToStructure
BinaryReader functions similarly to Marshal.PtrToStructure, allowing reading data from byte arrays. However, it incurs some additional overhead and is generally not recommended for performance-critical applications. Marshal.PtrToStructure operates directly on raw bytes without intermediate conversion, so performance is faster.

Yes, function overloading is a polymorphic form in C, specifically compile-time polymorphism. 1. Function overload allows multiple functions with the same name but different parameter lists. 2. The compiler decides which function to call at compile time based on the provided parameters. 3. Unlike runtime polymorphism, function overloading has no extra overhead at runtime, and is simple to implement but less flexible.

C has two main polymorphic types: compile-time polymorphism and run-time polymorphism. 1. Compilation-time polymorphism is implemented through function overloading and templates, providing high efficiency but may lead to code bloating. 2. Runtime polymorphism is implemented through virtual functions and inheritance, providing flexibility but performance overhead.

Yes, polymorphisms in C are very useful. 1) It provides flexibility to allow easy addition of new types; 2) promotes code reuse and reduces duplication; 3) simplifies maintenance, making the code easier to expand and adapt to changes. Despite performance and memory management challenges, its advantages are particularly significant in complex systems.

Polymorphisms in C are divided into runtime polymorphisms and compile-time polymorphisms. 1. Runtime polymorphism is implemented through virtual functions, allowing the correct method to be called dynamically at runtime. 2. Compilation-time polymorphism is implemented through function overloading and templates, providing higher performance and flexibility.

People who study Python transfer to C The most direct confusion is: Why can't you write like Python? Because C, although the syntax is more complex, provides underlying control capabilities and performance advantages. 1. In terms of syntax structure, C uses curly braces {} instead of indentation to organize code blocks, and variable types must be explicitly declared; 2. In terms of type system and memory management, C does not have an automatic garbage collection mechanism, and needs to manually manage memory and pay attention to releasing resources. RAII technology can assist resource management; 3. In functions and class definitions, C needs to explicitly access modifiers, constructors and destructors, and supports advanced functions such as operator overloading; 4. In terms of standard libraries, STL provides powerful containers and algorithms, but needs to adapt to generic programming ideas; 5
