打印随机设置的字符串？

Question

我怎么会让一个控制台写一些随机字符串，例如

string Test1 = "Test Hello!"; 
string Test2 = "Test2 Hello hows your day!"; 
string Test3 = "How are you today sir?"; 

我怎么会让一个程序，随机输出那些字符串？

Answer 1

该解决方案是很容易的：

Random rnd = new Random(); 

//List of all your strings in which we will select a random index 
List<string> sentences = new List<string> 
{ 
    "Test Hello!", 
    "Test2 Hello hows your day!", 
    "How are you today sir?" 
}; 

//Write one of the sentences randomly thanks to [rnd.Next][1] 
Console.WriteLine(sentences[rnd.Next(sentences.Count)]);

这里，将打印从时间列表x量一个随机字符串的解决方案：

var random = new Random(); 

var sentences = new List<string> 
{ 
    "Test Hello!", 
    "Test2 Hello hows your day!", 
    "How are you today sir?" 
}; 

Console.Write("How many random sentences would you like to print?: "); 

var count = 0; 

// Convert user input into the integer count variable, and continually print an error message 
// if the input is not an integer or if the integer is less than 0 
while (!int.TryParse(Console.ReadLine(), out count) || count < 0) 
{ 
    Console.WriteLine("Please enter a positive integer: "); 
} 

// Print out a random sentence for x (count) amount of times. 
while (count > 0) 
{ 
    // Will generate an index within the range of the list 
    var index = random.Next(0, sentences.Count() - 1); 

    Console.WriteLine(sentences[index]); 
    count--; 
} 

// Prevents the console from closing after the program is done executing. 
Console.WriteLine("Press any key to exit the application..."); 
Console.ReadKey();

或者，你可以做

 Random random = new Random(); 
     string[] testcases = new[] { 

      "Test Hello!", 
      "Test2 Hello hows your day!", 
      "How are you today sir?" 
     }; 

     Console.WriteLine(testcases[random.Next(0, testcases.Length)]); 
     Console.WriteLine(testcases[random.Next(0, testcases.Length)]); 
     Console.WriteLine(testcases[random.Next(0, testcases.Length)]);
