示例

以下示例处理 DivideByZeroException 整数除法中的异常。

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.

open System

let number1 = 3000
let number2 = 0
try
    printfn $"{number1 / number2}"
with :? DivideByZeroException ->
    printfn $"Division of {number1} by zero."

// 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 Decimal 数字除以零将引发异常 DivideByZeroException 。 若要防止异常，请确保具有整数或 Decimal 值的除法运算中的分母为非零。

将浮点值除以零不会引发异常;它根据 IEEE 754 算术规则，产生正无穷大、负无穷大或非数字（NaN）。 由于以下示例使用浮点除法而不是整数除法，因此该操作不会引发 DivideByZeroException 异常。

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

open System

let number1 = 3000.
let number2 = 0.

printfn $"{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
