小数。C# 中的 ToInt16()方法
原文:https://www . geesforgeks . org/decimal-to int 16-method-in-c-sharp/
此方法用于将指定的十进制值转换为等效的 16 位有符号整数。用户还可以使用显式赋值运算符将十进制值转换为 16 位整数。
语法:公共静态短 ToInt16(十进制值)； 这里值是要转换的小数。
返回值:返回一个 16 位有符号整数，相当于指定的值。
异常:如果指定值小于最小值或大于最大值，此方法将给出overoverover Exception。
以下程序说明了上述方法的使用:
例 1:
// C# program to demonstrate the
// Decimal.ToInt16(Decimal) Method
using System;
class GFG {
// Main Method
public static void Main()
{
try {
// Taking decimal variables
Decimal dec1 = 21564.236M;
Decimal dec2 = 32767.256m;
// using Decimal.ToInt16(Decimal) Method
// Here short means Int16
short val1 = Decimal.ToInt16(dec1);
// using Decimal.ToInt16(Decimal) Method
// Here short means Int16
short val2 = Decimal.ToInt16(dec2);
// Printing the Int16 value
Console.WriteLine("The Int16 value "
+ "is : {0}", val1);
// Printing the Int16 value
Console.WriteLine("The Int16 value "
+ "is : {0}", val2);
}
catch (OverflowException e)
{
Console.Write("Exception Thrown: ");
Console.Write("{0}", e.GetType(), e.Message);
}
}
}
Output:
The Int16 value is : 21564
The Int16 value is : 32767
例 2: 适用于飞越异常
// C# program to demonstrate the
// Decimal.ToInt16(Decimal) Method
using System;
class GFG {
// Main Method
public static void Main()
{
try {
// Taking decimal variable
// Taking the maximum value
// of Decimal
Decimal dec1 = Decimal.MaxValue;
// using Decimal.ToInt16(Decimal) Method
// Here short means Int16
// It will give error as Decimal.MaxValue
// value is out of range from Int16
short val1 = Decimal.ToInt16(dec1);
// Printing the Int16 value
Console.WriteLine("The Int16 value "
+ "is : {0}", val1);
}
catch (OverflowException e)
{
Console.Write("Exception Thrown: ");
Console.Write("{0}", e.GetType(), e.Message);
}
}
}
Output:
Exception Thrown: System.OverflowException
