获取表示ValueTuple值的字符串<T1,T2,T3,T4,T5,T6,T7,TRest>C＃中的实例

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。您还可以在ToString方法的帮助下获得一个表示ValueTuple对象值的字符串。
此方法返回一个字符串，该字符串将表示ValueTuple 对象的值。此方法表示的字符串的格式为(Item1，Item2，Item3，Item4，Item5，Item6，Item7，Item8 ..)，其中Item1，Item2，Item3，Item4，Item5，Item6，Item7表示Item1的值， Item2，Item3，Item4，Item5，Item6，Item7属性和Item8表示ValueTuple 对象的Next.Item1属性的值以及任何其他嵌套的值组件之后是Item8。如果任何属性包含空值，它将表示一个String.Empty 。

句法：

public override string ToString ();

返回类型：此方法的返回类型为System.String 。所以，它会返回一个表示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 = ValueTuple.Create("Rina");
              
            // Get the value of ValueTuple
            // With the help of ToString method
            Console.WriteLine("ValueTuple 1: " + v1.ToString());
  
            // 2-ValueTuple
            var v2 = ValueTuple.Create("Rohan", 25);
              
            // Get the value of ValueTuple
            // With the help of ToString method
            Console.WriteLine("ValueTuple 2: " + v2.ToString());
  
            // 3-ValueTuple
            var v3 = ValueTuple.Create("Rima", 22, 2016);
              
            // Get the value of ValueTuple
            // With the help of ToString method
            Console.WriteLine("ValueTuple 3: " + v3.ToString());
  
            // 4-ValueTuple
            var v4 = ValueTuple.Create("Mohit", 28, 
                          2014, "Junior Engineer");
                            
            // Get the value of ValueTuple
            // With the help of ToString method
            Console.WriteLine("ValueTuple 4: " + v4.ToString());
  
        }
    }
}

输出：

ValueTuple 1: (Rina)
ValueTuple 2: (Rohan, 25)
ValueTuple 3: (Rima, 22, 2016)
ValueTuple 4: (Mohit, 28, 2014, Junior Engineer)

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)
        {
            // 5-ValueTuple
            var v5 = ValueTuple.Create("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 = ValueTuple.Create("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 = ValueTuple.Create("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 = ValueTuple.Create("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 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))
