范围结构在C#8.0中引入。它表示具有开始索引和结束索引的范围。您可以在Range结构提供的End Property的帮助下找到给定范围的结束索引。
句法:
public property Index End { Index get(); };
在此,索引表示结束索引。
范例1:
// C# program to illustrate the use
// of End property of Range struct
using System;
namespace range_example {
class Program {
static void Main(string[] args)
{
// Creating range
// using Range Constructor
var r1 = new Range(0, 5);
// Creating range
// using range operator
Range r2 = 3..7;
// Finding the last index
// of r1 and r2 ranges
// Using End property
var res1 = r1.End;
Console.WriteLine("End index of r1 range: " + res1);
var res2 = r2.End;
Console.WriteLine("End index of r2 range: " + res2);
}
}
}
输出:
End index of r1 range: 5
End index of r2 range: 7
范例2:
// C# program to illustrate how to use
// End property of Range structure
using System;
namespace range_example {
class GFG {
// Main Method
static void Main(string[] args)
{
// Creating and initailizing an array
string[] arr = new string[8] {"Archery", "Badminton", "Cricket",
"Bowling", "Boxing", "Curling", "Tennis", "Skateboarding"};
// Creating ranges
// Using Range(Index, Index)
// Constructor
var r1 = new Range(0, 3);
var r2 = new Range(4, 7);
// Finding the last index
// of the specified range
// Using End property
var res1 = r1.End;
var res2 = r2.End;
Console.WriteLine("End Index of Range {0} is {1}"+
" and the item is {2}", r1, res1, arr[res1]);
Console.WriteLine("End Index of Range {0} is {1} and"+
" the item is {2}", r2, res2, arr[res2]);
}
}
}
输出:
End Index of Range 0..3 is 3 and the item is Bowling
End Index of Range 4..7 is 7 and the item is Skateboarding
