重要

此 API 不符合 CLS。

返回一个值,该值指示 64 位无符号整数是否小于等于 BigInteger 值。Returns a value that indicates whether a 64-bit unsigned integer is less than or equal to a BigInteger value.

public:
 static bool operator <=(System::UInt64 left, System::Numerics::BigInteger right);
[System.CLSCompliant(false)]
public static bool operator <= (ulong left, System.Numerics.BigInteger right);
static member ( <= ) : uint64 * System.Numerics.BigInteger -> bool
Public Shared Operator <= (left As ULong, right As BigInteger) As Boolean

参数

left
UInt64

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

如果 true 小于等于 left,则为 right;否则为 falsetrue if left is less than or equal to right; otherwise, false.

注解

LessThanOrEqual 方法定义 BigInteger 值的小于或等于运算符的运算。The LessThanOrEqual method defines the operation of the less than or equal to operator for BigInteger values. 它可以实现如下所示的代码:It enables code such as the following:

BigInteger number = BigInteger.Parse("9801324316220166912");
if (UInt64.MaxValue <= number)
{
   // Do something.
}
else
{
   // Do something else.
}      
Dim number As BigInteger = BigInteger.Parse("9801324316220166912")
If UInt64.MaxValue <= number Then
   ' Do something.
Else
   ' Do something else.
End If      

不支持自定义运算符的语言可以改为调用 BigInteger.CompareTo(UInt64) 方法。Languages that do not support custom operators can call the BigInteger.CompareTo(UInt64) method instead. 它们还可以直接调用 LessThanOrEqual(UInt64, BigInteger) 方法,如下例所示。They can also call the LessThanOrEqual(UInt64, BigInteger) method directly, as the following example shows.

Dim number As BigInteger = BigInteger.Parse("9801324316220166912")
If BigInteger.op_LessThanOrEqual(UInt64.MaxValue, number) Then
   ' Do something.
Else
   ' Do something else.
End If      

此运算符的等效方法是 BigInteger.CompareTo(UInt64)The equivalent method for this operator is BigInteger.CompareTo(UInt64).
