获取表示ValueTuple值的字符串<T1,T2,T3,T4,T5,T6>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)，其中Item1，Item2，Item3，Item4，Item5，Item6代表Item1，Item2，Item3，Item4，Item5， Item6属性，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 。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 = 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());
  
        }
    }
}

输出：

ValueTuple 5: (Rohit, 32, 2010, CSE, Junior Engineer)
ValueTuple 6: (Sunita, 25, 2015, ECE, Junior Engineer, 102)
