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

元组是一种数据结构，它为您提供了表示数据集的最简单方法。您还可以使用ToString方法获得表示元组对象的字符串。此方法返回一个字符串，该字符串将表示Tuple 对象。此方法表示的字符串的格式为(Item1，Item2，Item3，Item4，Item5，Item6，Item7)，其中Item1，Item2，Item3，Item4，Item5，Item6，Item7表示Item1，Item2，Item3的值， Item4，Item5，Item6，Item7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Tuple 对象的字符串。

范例1：

// C# program to illustrate the
// use of ToString method
using System;
  
namespace exampleoftuple {
  
class GFG {
  
    // Main Method
    static void Main(string[] args)
    {   
  
        // 1-Tuple
        var v1 = Tuple.Create("Rohit");
  
        // Get the value of Tuple
        // With the help of ToString method
        Console.WriteLine("Tuple 1: " + v1.ToString());
  
        // 2-Tuple
        var v2 = Tuple.Create("Sheema", "Riya");
  
        // Get the value of Tuple
        // With the help of ToString method
        Console.WriteLine("Tuple 2: " + v2.ToString());
  
        // 3-Tuple
        var v3 = Tuple.Create("Rima", "Suman", "Sohan");
  
        // Get the value of Tuple
        // With the help of ToString method
        Console.WriteLine("Tuple 3: " + v3.ToString());
  
        // 4-Tuple
        var v4 = Tuple.Create("Shilpa", "Susma",
                              "Sumit", "Rohan");
  
        // Get the value of Tuple
        // With the help of ToString method
        Console.WriteLine("Tuple 4: " + v4.ToString());
    }
}
}

输出：

Tuple 1: (Rohit)
Tuple 2: (Sheema, Riya)
Tuple 3: (Rima, Suman, Sohan)
Tuple 4: (Shilpa, Susma, Sumit, Rohan)

范例2：

// C# program to illustrate 
// the use of ToString method
using System;
  
namespace exampleoftuple {
  
class GFG {
  
    // Main Method
    static public void Main()
    {
  
        // 5-Tuple
        var v5 = Tuple.Create(2, 4, 6, 8, 10);
  
        // Get the value of Tuple
        // With the help of ToString method
        Console.WriteLine("Tuple 5: " + v5.ToString());
  
        // 6-Tuple
        var v6 = Tuple.Create(3, 6, 9, 12, 15, 18);
  
        // Get the value of Tuple
        // With the help of ToString method
        Console.WriteLine("Tuple 6: " + v6.ToString());
  
        // 7-Tuple
        var v7 = Tuple.Create(12, 45, 67, 78, 87, 97, 87);
  
        // Get the value of Tuple
        // With the help of ToString method
        Console.WriteLine("Tuple 7: " + v7.ToString());
    }
}
}

输出：

Tuple 5: (2, 4, 6, 8, 10)
Tuple 6: (3, 6, 9, 12, 15, 18)
Tuple 7: (12, 45, 67, 78, 87, 97, 87)
