C#功能测试

List 内部元素为引用

src[0]为"11"

List<Source> src = new List<Source>(); src.Add(new Source() { Name = "1", Age = 1, Description = "1" }); src.Add(new Source() { Name = "2", Age = 2, Description = "2" }); foreach (var source in src) { source.Name = "11"; } Console.WriteLine(src[0].Name); 内部元素非引用

不能赋值，会报错
