可以通过实例得到详细结论: using System; // 定义一个矩形类，类属于引用类型 class RefRectangle { public int width; public int height; } // 定义一个矩形结构，属于值类型 struct ValRectangle { public int width; public int height; }
class RefValRectangle { public static void Main() { // 创建一个矩形对象，并将值传递给另一个新对象. RefRectangle ref1 = new RefRectangle(); ; ref1.width = 3; ref1.height = 4; RefRectangle ref3 = ref1; Console.WriteLine("Dimensions of ref1 are : " + ref3.width.ToString() + "..." + ref3.height.ToString()); Console.WriteLine("Change Dimensions of ref1"); ref1.width = 10; ref1.height = 50; bool bTransfer = ref3.Equals(ref1); Console.WriteLine("Dimensions of ref1 now are : " + ref3.width.ToString() + "....." + ref3.height.ToString()); Console.WriteLine(bTransfer.ToString()); Console.ReadLine(); // 创建一个矩形结构，将值传递给一个新的矩形结构 ValRectangle val1 = new ValRectangle(); val1.width = 3; val1.height = 4; ValRectangle val3 = val1; Console.WriteLine("Dimensions of val1 are : " + val3.width.ToString() + "..." + val3.height.ToString()); Console.WriteLine("Change Dimensions of val1"); val1.width = 10; val1.height = 50; bool bPass = val3.Equals(val1); Console.WriteLine("Dimensions of val1 now are : " + val3.width.ToString() + "....." + val3.height.ToString()); Console.WriteLine(bPass.ToString()); Console.ReadLine(); } }
