我习惯反对MyClass,我需要提出3个例子。
不要做这样的事情:
MyClass instance1 = new MyClass();
MyClass instance2 = new MyClass();
MyClass instance3 = new MyClass();
顺便说一句:
MyClass[] instances = new MyClass();
instances[0].somemethod;
?

MyClass[] instances = new MyClass[3];
for (int i = 0; i < instances.Length; i++)
instances[i] = new MyClass();
是否在休息室里:
MyClass[] instances=new MyClass[3];
for(int i=0;i<3;i++)
{
instances[i]= new MyClass();
}
或直接创建阵列:
MyClass[] instances= new MyClass[]{new MyClass(), new MyClass(), new MyClass()};
用途
MyClass[] instances = new MyClass[num];
f或 (int i=0; i<num; i++)
{
instances[i]=new MyClass();
}
或
MyClass[] instances = new MyClass[]{ new MyClass(), new MyClass(), new MyClass()};
页: 1
MyClass[] instances = Enumerable.Repeat(0, 3).Select(i => new MyClass()).ToArray();
业绩考虑留待读者。
使用林克:
MyClass[] instances Enumerable.Range(0, 3).Select(_ => new MyClass()).ToArray();
起始值0
确实如此,我们只是想要一些有3个要素的EE。 或者,<代码>。 Repeat也发挥了作用,只是忽视了第一个论点。
