But I get error
CS0029 C # Can not implicitly convert type 'string' to 'Project.Animals'
推荐答案
animals[2] = "Dog";
但是(根据编译器)你定义了 animals
作为 Animals
的集合,而不是字符串的集合。所以你需要创建一个新的Animal并将其分配给你的列表,例如:
But (according to the compiler) you defined animals
as a collection of Animals
, not a collection of strings. So you need to create a new Animal and assign that to your list, like:
Animals newDog = new Animals(1, "Dog");
animals[2] = newDog;
