You can use the stringconstructor:
您可以使用string构造函数：
Console.WriteLine(new string('.', 10));
Initializes a new instance of the String class to the value indicated by a specified Unicode character repeated a specified number of times.
将 String 类的新实例初始化为重复指定次数的指定 Unicode 字符所指示的值。

I would say the most straight forward answer is to use a forloop. This uses less storage.
我会说最直接的答案是使用for循环。这使用较少的存储。
for (int i = 0; i < 10; i++)
Console.Write('.');
Console.WriteLine();
But you can also allocate a string that contains the repeated characters. This involves less typing and is almost certainly faster.
但是您也可以分配一个包含重复字符的字符串。这涉及较少的输入并且几乎可以肯定更快。
Console.WriteLine(new String('.', 10));

try something like this
尝试这样的事情
string print = "";
for(int i = 0; i< 10 ; i++)
{
print = print + ".";
}
Console.WriteLine(print);

You can use one of the 'string' constructors, like so:
您可以使用“字符串”构造函数之一，如下所示：
Console.WriteLine(new string('.', 10));
