BigInteger.Max(BigInteger, BigInteger) 方法

定义

返回两个 BigInteger 值中的较大者。Returns the larger of two BigInteger values.

public:
 static System::Numerics::BigInteger Max(System::Numerics::BigInteger left, System::Numerics::BigInteger right);
public static System.Numerics.BigInteger Max (System.Numerics.BigInteger left, System.Numerics.BigInteger right);
static member Max : System.Numerics.BigInteger * System.Numerics.BigInteger -> System.Numerics.BigInteger
Public Shared Function Max (left As BigInteger, right As BigInteger) As BigInteger

参数

left
BigInteger

要比较的第一个值。The first value to compare.

right
BigInteger

要比较的第二个值。The second value to compare.

返回

leftright 参数中较大的一个。The left or right parameter, whichever is larger.

示例

下面的示例使用 Max 方法来选择 BigInteger 值数组中的最大数字。The following example uses the Max method to select the largest number in an array of BigInteger values.

using System;
using System.Numerics;

public class Example
{
   public static void Main()
   {
      BigInteger[] numbers = { Int64.MaxValue * BigInteger.MinusOne, 
                               BigInteger.MinusOne, 
                               10359321239000, 
                               BigInteger.Pow(103988, 2),
                               BigInteger.Multiply(Int32.MaxValue, Int16.MaxValue), 
                               BigInteger.Add(BigInteger.Pow(Int64.MaxValue, 2), 
                               BigInteger.Pow(Int32.MaxValue, 2)) };
      if (numbers.Length < 2)
      { 
         Console.WriteLine("Cannot determine which is the larger of {0} numbers.",
                            numbers.Length);
         return;
      }
           
      BigInteger largest = numbers[numbers.GetLowerBound(0)];
      
      for (int ctr = numbers.GetLowerBound(0) + 1; ctr <= numbers.GetUpperBound(0); ctr++)
         largest = BigInteger.Max(largest, numbers[ctr]);

      Console.WriteLine("The values:");
      foreach (BigInteger number in numbers)
         Console.WriteLine("{0,55:N0}", number);

      Console.WriteLine("\nThe largest number of the series is:");
      Console.WriteLine("   {0:N0}", largest);
   }
}
// The example displays the following output:
//       The values:
