Question

嗨我试着这样做，所以我可以生成一个随机数1-35，所以例如如果数字是25，它将写出一个字符串25等号。我怎么能这样做？

Random r = new Random();
r.next(1, 35);
R's result = 25
string result = 25 equal signs

Answer 1

班级string有constructor可以为您完成工作。

Random r = new Random();
int number = r.next(1, 35);
string result = new string('=', number);

Answer 2

另请注意，r.Next()不应为r.next()。

Random r = new Random();
int occurrences = r.Next(1, 35);
StringBuilder sb = new StringBuilder();
for (int i = 0; i < occurrences; i++)
{
     sb.Append('=');
}

string output = sb.ToString();

Console.WriteLine(output);

Answer 3

您需要循环重复向结果中添加=。将代码更新为

Random r = new Random();
int total = r.next(1, 35);
string result = "";
for (int i = 0; i < total; i++)
{
    result += "=";
}

随机生成1个字符随机数量
