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。您可以使用GetType方法获取元组对象的类型。此方法将返回元组对象的类型。此方法是从Object类继承的。
句法：
public Type GetType ();返回类型：此方法的返回类型为Type 。表示它返回Tuple <>对象的类型，其中Tuple <>可以是1元组，2元组，3元组，4元组，5元组或6元组或7 -tuple，或8-tuple。
下面的程序说明了上述讨论方法的用法：
范例1：
// C# program to illustrate the
// use of GetType method
using System;
class GFG {
// Main Method
static public void Main()
{
// Taking 1-Tuple
var v1 = Tuple.Create("Geeks");
Console.WriteLine("Type of the element of 1-Tuple: " + v1.Item1.GetType());
Console.WriteLine();
// Taking 2-Tuple
var v2 = Tuple.Create("GeeksforGeeks", 23);
Console.WriteLine("Type of the First Element of 2-Tuple: " + v2.Item1.GetType());
Console.WriteLine("Type of the Second Element of 2-Tuple: " + v2.Item2.GetType());
Console.WriteLine();
// Taking 3-Tuple
var v3 = Tuple.Create("geeks", 234, 90.9);
Console.WriteLine("Type of the First element of 3-Tuple: " + v3.Item1.GetType());
Console.WriteLine("Type of the Second element of 3-Tuple: " + v3.Item2.GetType());
Console.WriteLine("Type of the Third element of 3-Tuple: " + v3.Item3.GetType());
Console.WriteLine();
// Taking 4-Tuple
var v4 = Tuple.Create("geeks", 567, 56.7, 'g');
Console.WriteLine("Type of the First element of 3-Tuple: " + v4.Item1.GetType());
Console.WriteLine("Type of the Second element of 3-Tuple: " + v4.Item2.GetType());
Console.WriteLine("Type of the Third element of 3-Tuple: " + v4.Item3.GetType());
Console.WriteLine("Type of the Fourth element of 3-Tuple: " + v4.Item4.GetType());
// Taking 7-Tuple
var v7 = Tuple.Create("geeks", 234.0, 90.9f, 56.6m, 67.8, true, 67.8);
Console.WriteLine("Type of the First element of 7-Tuple: " + v7.Item1.GetType());
Console.WriteLine("Type of the Second element of 7-Tuple: " + v7.Item2.GetType());
Console.WriteLine("Type of the Third element of 7-Tuple: " + v7.Item3.GetType());
Console.WriteLine("Type of the Fourth element of 7-Tuple: " + v7.Item4.GetType());
Console.WriteLine("Type of the Fifth element of 7-Tuple: " + v7.Item5.GetType());
Console.WriteLine("Type of the Sixth element of 7-Tuple: " + v7.Item6.GetType());
Console.WriteLine("Type of the Seventh element of 7-Tuple: " + v7.Item7.GetType());
Console.WriteLine();
}
}
输出：
Type of the element of 1-Tuple: System.String
Type of the First Element of 2-Tuple: System.String
Type of the Second Element of 2-Tuple: System.Int32
Type of the First element of 3-Tuple: System.String
Type of the Second element of 3-Tuple: System.Int32
Type of the Third element of 3-Tuple: System.Double
Type of the First element of 3-Tuple: System.String
Type of the Second element of 3-Tuple: System.Int32
Type of the Third element of 3-Tuple: System.Double
Type of the Fourth element of 3-Tuple: System.Char
Type of the First element of 7-Tuple: System.String
Type of the Second element of 7-Tuple: System.Double
Type of the Third element of 7-Tuple: System.Single
Type of the Fourth element of 7-Tuple: System.Decimal
Type of the Fifth element of 7-Tuple: System.Double
Type of the Sixth element of 7-Tuple: System.Boolean
Type of the Seventh element of 7-Tuple: System.Double
