先上代码

 1 class TestClass
 2 {
 3     public int val;
 4 }
 5 struct TestStruct
 6 {
 7     public int val;
 8 }
 9 
10 class Program
11 {
12     static void Main(string[] args)
13     {
14         TestClass testClass1 = new TestClass();
15         TestClass testClass2 = testClass1;
16         testClass1.val = 10;
17         testClass2.val = 20;
18 
19         TestStruct testStruct1 = new TestStruct();
20         TestStruct testStruct2 = testStruct1;
21         testStruct1.val = 30;
22         testStruct2.val = 40;
23 
24         WriteLine($"testClass1.val = {testClass1.val}");
25         WriteLine($"testClass2.val = {testClass2.val}");
26         WriteLine($"testStruct1.val = {testStruct1.val}");
27         WriteLine($"testStruct2.val = {testStruct2.val}");
28 
29         ReadKey();
30 
31     }
