定义

命名空间:

System.Numerics

程序集:

System.Runtime.Numerics.dll

Source:

BigInteger.cs

返回两个 BigInteger 值中的较大者。

public:
 static System::Numerics::BigInteger Max(System::Numerics::BigInteger left, System::Numerics::BigInteger right) = System::Numerics::INumber<System::Numerics::BigInteger>::Max;

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。

right

BigInteger

要比较的第二个值。

返回

BigInteger

left 或 right 参数中较大的一个。

实现

Max(TSelf, TSelf)

示例

以下示例使用 Max 方法选择值数组 BigInteger 中的最大数字。

using System;
using System.Numerics;
