如何获取表示C＃中的ValueTuple实例的字符串？

ValueTuple是C＃7.0中引入的结构，表示值类型Tuple。它允许您存储一个数据集，该数据集包含可能彼此相关或不相关的多个值。在ToString方法的帮助下，您还可以获得代表ValueTuple对象的字符串。此方法返回一个表示ValueTuple对象的字符串。此方法表示的字符串为()形式。

句法：

public override string ToString ();

返回类型：此方法的返回类型为System.String 。因此，它将返回一个表示ValueTuple对象的字符串。

范例1：

// C# program to illustrate 
// the use of ToString method
using System;
  
namespace exampleofvaluetuple {
  
class GFG {
  
    // Main Method
    static void Main(string[] args)
    {
  
        // 1-ValueTuple
        var v1 = ("Rina");
  
        // Get the value of ValueTuple
        // With the help of ToString method
        Console.WriteLine("ValueTuple 1: " + v1.ToString());
  
        // 2-ValueTuple
        var v2 = ("Rohan", 25);
  
        // Get the value of ValueTuple
        // With the help of ToString method
        Console.WriteLine("ValueTuple 2: " + v2.ToString());
  
        // 3-ValueTuple
        var v3 = ("Rima", 22, 2016);
  
        // Get the value of ValueTuple
        // With the help of ToString method
        Console.WriteLine("ValueTuple 3: " + v3.ToString());
  
        // 4-ValueTuple
        var v4 = ("Mohit", 28, 2014, "Junior Engineer");
  
        // Get the value of ValueTuple
        // With the help of ToString method
        Console.WriteLine("ValueTuple 4: " + v4.ToString());
  
        // 5-ValueTuple
        var v5 = ("Rohit", 32, 2010, "CSE", "Junior Engineer");
  
        // Get the value of ValueTuple
        // With the help of ToString method
        Console.WriteLine("ValueTuple 5: " + v5.ToString());
  
        // 6-ValueTuple
        var v6 = ("Sunita", 25, 2015, "ECE",
                    "Junior Engineer", 102);
  
        // Get the value of ValueTuple
        // With the help of ToString method
        Console.WriteLine("ValueTuple 6: " + v6.ToString());
  
        // 7-ValueTuple
        var v7 = ("Sonu", 22, 2016, "CSE", 
        "Junior Engineer", 104, "C++");
  
        // Get the value of ValueTuple
  
        // With the help of ToString method
        Console.WriteLine("ValueTuple 7: " + v7.ToString());
  
        // 8-ValueTuple
        var v8 = ("Susmita", 28, 2014, "Junior Engineer",
                109, "Java", ValueTuple.Create("Cricket", 
                            "Football", "Volleyball"));
  
        // Get the value of ValueTuple
        // With the help of ToString method
        Console.WriteLine("ValueTuple 8: " + v8.ToString());
    }
}
}

输出：

ValueTuple 1: Rina
ValueTuple 2: (Rohan, 25)
ValueTuple 3: (Rima, 22, 2016)
ValueTuple 4: (Mohit, 28, 2014, Junior Engineer)
ValueTuple 5: (Rohit, 32, 2010, CSE, Junior Engineer)
ValueTuple 6: (Sunita, 25, 2015, ECE, Junior Engineer, 102)
ValueTuple 7: (Sonu, 22, 2016, CSE, Junior Engineer, 104, C++)
ValueTuple 8: (Susmita, 28, 2014, Junior Engineer, 109, Java, (Cricket, Football, Volleyball))

范例2：

// C# program to illustrate 
// the use of ToString method
using System;
   
namespace exampleofvaluetuple {
   
class GFG {
   
    // Main Method
    static void Main(string[] args)
    {
        // Nested Value Tuples
        var Emp1 = (Name: "Anu", Age : 23, 
          Languages: ValueTuple.Create("C++",
                    "Java", "Python", "C#"));
   
        var Emp2 = (Name: "Boond", Age : 27, Post: "Junior Engineer",
                        Languages: ValueTuple.Create("C++", "Java"));
   
        var Emp3 = (Name: "Rohit", Age : 25, Post: "HR",
                     Languages: ValueTuple.Create("C++", 
                                         "Java", "C#"));
   
        var Emp4 = (Name: "Mohan", Age : 26, Post: "Junior Engineer",
              Languages: ValueTuple.Create("C++", "Java", "Python"));
   
        // Get the value of Nested ValueTuples
        // With the help of ToString method
        Console.WriteLine("NValueTuple 1: {0}", Emp1.ToString());
        Console.WriteLine("NValueTuple 2: {0}", Emp2.ToString());
        Console.WriteLine("NValueTuple 3: {0}", Emp3.ToString());
        Console.WriteLine("NValueTuple 4: {0}", Emp4.ToString());
    }
}
}

输出：

NValueTuple 1: (Anu, 23, (C++, Java, Python, C#))
NValueTuple 2: (Boond, 27, Junior Engineer, (C++, Java))
NValueTuple 3: (Rohit, 25, HR, (C++, Java, C#))
NValueTuple 4: (Mohan, 26, Junior Engineer, (C++, Java, Python))
