csharp类、引用类型(class)与结构、值类型(struct)的区别 数据在内存中的存储位置,取决于它的数据类型,在C#中,分为值类型和引用类型,值类型的数据存储在内存中的堆栈中,每个变量或程序都有自己的堆栈,不可以共用一个堆栈地址。当数据一个值类型的变量传递到另一个相同类型的变量时,会在堆栈中分配两个不同的地址...

Example: Parameterized Constructor in Struct Copy struct Coordinate { public int x; public int y; public Coordinate(int x, int y) { this.x = x; this.y = y; } } Coordinate point = new Coordinate(10, 20); Console.WriteLine(point.x); //output: 10 Console.WriteLine(point.y); //outp...
In the example, we create a point. The Point struct has two readonly properties: X and Y. public double X { get; init; } public double Y { get; init; } The init keyword creates an init-only setter. It assigns a value to the property only during object construction. This enforces...

CsharpServer Side ProgrammingProgramming The Decimal Struct in C# Represents a decimal floating-point number. The Decimal value type represents decimal numbers ranging from positive 79,228,162,514,264,337,593,543,950,335 to negative 79,228,162,514,264,337,593,543,950,335. The default value ...
系统看了下 csharp 和 rust 的各种性能测试比较,很多情况下,csharp 的内存占用要远大于 rust 的,即使上了 aot 也是这样,性能上很多时候也要低一些。感觉csharp 现在做带 gc 的高性能开发还缺些东西。像图像这样的连续内存的结构没问题,树啊,图啊这样的就有问题了,直接用 object 呢,内存占用太高,用 struct...
