初学者对 : Controller where T : class,new() 不理解 ,我是初学者的时候也一样不理解,在此做个简单的解释:
这是类型参数约束,.NET支持的类型参数约束有以下五种:where T : struct | T必须是一个结构类型where T : class | T必须是一个类(class)类型,不能是结构(structure)类型where T : new() | T必须要有一个无参构造函数where T : NameOfBaseClass | T必须继承名为NameOfBaseClass的类where T : NameOfInterface | T必须实现名为NameOfInterface的接口
详细解决方案
部类参数约束 : Controller where T : class,new()
