使用 WHERE 子句 LINQ 查找数组中最大数的 C# 程序

LINQ 被称为语言集成查询，它是在 .NET 3.5 中引入的。它使.NET语言能够生成查询以从数据源中检索数据。它消除了编程语言和数据库之间的不匹配，并且无论使用哪种类型的数据源，用于创建查询的语法都是相同的。在本文中，我们将学习如何使用 WHERE 子句 LINQ 查找数组中的最大数。在这里，我们将获得大于给定数组中特定数字的数字。

例子：

Input: Array of Integers: 100,200,300,450,324,56,77,890
Value: 500
Output: Numbers greater than 500 are: 890
      
Input: Array of Integers: 34,56,78,100,200,300,450,324,56,77,890
Value: 100
Output: Numbers greater than 100 are: 200,300,450,324,890

方法：

To display the greatest numbers in an array using WHERE Clause LINQ follow the following approach:

1. Store integer(input) in an array.
2. The sum of the elements is calculated using the for loop.
3. The numbers which are greater than particular value is checked using where function.
4. By using the LINQ query we will store the numbers in an iterator.
5. Now the iterator is iterated and the integers are printed.

例子：

C#

// C# program to print the greatest numbers in an array
// using WHERE Clause LINQ
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
   
class GFG{
  
static void Main()
{
      
    // Array of numbers
    int[] array1 = { 34, 56, 78, 100, 200, 300,
                     450, 324, 56, 77, 890 };
      
    // Now get the numbers greater than 100 and 
    // store in big variable using where clause
    var big = from value in array1 where value > 100 select value;
    Console.WriteLine("Numbers that are greater than 100 are  :");
      
    // Get the greater numbers
    foreach (var s in big)
    {
        Console.Write(s.ToString() + " ");
    }
    Console.Read();
}
}

输出：

Numbers that are greater than 100 are  :
200 300 450 324 890
