示例
下面的示例 DivideByZeroException 在整数相除中处理异常。The following example handles a DivideByZeroException exception in integer division.
using System;
public class Example
{
public static void Main()
{
int number1 = 3000;
int number2 = 0;
try {
Console.WriteLine(number1 / number2);
}
catch (DivideByZeroException) {
Console.WriteLine("Division of {0} by zero.", number1);
}
}
}
// The example displays the following output:
// Division of 3000 by zero.
Module Example
Public Sub Main()
Dim number1 As Integer = 3000
Dim number2 As Integer = 0
Try
Console.WriteLine(number1\number2)
Catch e As DivideByZeroException
Console.WriteLine("Division of {0} by zero.", number1)
End Try
End Sub
End Module
' The example displays the following output:
' Division of 3000 by zero.
注解
尝试将整数或数字除以 Decimal 零会引发 DivideByZeroException 异常。Trying to divide an integer or Decimal number by zero throws a DivideByZeroException exception. 若要防止出现此异常,请确保包含整数或值的除法运算中的分母 Decimal 为非零值。To prevent the exception, ensure that the denominator in a division operation with integer or Decimal values is non-zero.
将浮点值除以零不会引发异常;根据 IEEE 754 算法的规则,它会导致正无穷、负无穷或非 (NaN) 的数字。Dividing a floating-point value by zero doesn't throw an exception; it results in positive infinity, negative infinity, or not a number (NaN), according to the rules of IEEE 754 arithmetic. 由于下面的示例使用浮点除法而不是整数除法,因此操作不会引发 DivideByZeroException 异常。Because the following example uses floating-point division rather than integer division, the operation does not throw a DivideByZeroException exception.
using System;
public class Example
{
public static void Main()
{
int number1 = 3000;
int number2 = 0;
Console.WriteLine((double)number1 / number2);
}
}
// The example displays the following output:
// Infinity
Module Example
Public Sub Main()
Dim number1 As Integer = 3000
Dim number2 As Integer = 0
Console.WriteLine(number1/number2)
End Sub
End Module
' The example displays the following output:
' Infinity
