C＃Random在foreach中生成相同的值

Question

我想在每次重复foreach循环

时得到随机数

 @foreach (var item in Model)
        {
            Random r = new Random();
            int s = r.Next(0, 5);                                             
            <span>@(s)</span>                   
        }

但我得到相同的值而不是随机值。

Answer 1

Random r = new Random();

@foreach (var item in Model)
        {
            int s = r.Next(0, 5);                                             
            <span>@(s)</span>                   
        }
