表示 Int16 的最大可能值。 此字段为常数。
public: short MaxValue = 32767;public const short MaxValue = 32767;val mutable MaxValue : int16Public Const MaxValue As Short = 32767字段值
Value = 32767示例
下面的示例使用 MaxValue 属性在转换为Int16值时阻止 OverflowException 。
array<Int64>^ numbersToConvert = {162345, 32183, -54000};
Int16 newNumber;
for each (Int64 number in numbersToConvert)
{
if (number >= Int16::MinValue && number <= Int16::MaxValue)
{
newNumber = Convert::ToInt16(number);
Console::WriteLine("Successfully converted {0} to an Int16.",
newNumber);
}
else
{
Console::WriteLine("Unable to convert {0} to an Int16.", number);
}
}
// The example displays the following output:
// Unable to convert 162345 to an Int16.
// Successfully converted 32183 to an Int16.
// Unable to convert -54000 to an Int16.
long[] numbersToConvert = {162345, 32183, -54000};
short newNumber;
foreach (long number in numbersToConvert)
{
if (number >= Int16.MinValue && number <= Int16.MaxValue)
{
newNumber = Convert.ToInt16(number);
Console.WriteLine($"Successfully converted {newNumber} to an Int16.");
}
else
{
Console.WriteLine($"Unable to convert {number} to an Int16.");
}
}
// The example displays the following output to the console:
// Unable to convert 162345 to an Int16.
// Successfully converted 32183 to an Int16.
// Unable to convert -54000 to an Int16.
open System
let numbersToConvert = [ 162345L; 32183L; -54000L ]
for number in numbersToConvert do
if number >= int64 Int16.MinValue && number <= int64 Int16.MaxValue then
let newNumber = Convert.ToInt16 number
printfn $"Successfully converted {newNumber} to an Int16."
else
printfn $"Unable to convert {number} to an Int16."
// The example displays the following output to the console:
// Unable to convert 162345 to an Int16.
// Successfully converted 32183 to an Int16.
// Unable to convert -54000 to an Int16.
Dim numbersToConvert() As Long = {162345, 32183, -54000}
Dim newNumber As Int16
For Each number As Long In NumbersToConvert
If number >= Int16.MinValue And number <= Int16.MaxValue Then
newNumber = Convert.ToInt16(number)
Console.WriteLine("Successfully converted {0} to an Int16.", _
newNumber)
Else
Console.WriteLine("Unable to convert {0} to an Int16.", number)
End If

' The example displays the following output to the console:

注解
此常量的值为 32767;即十六进制0x7FFF。
属性 MaxValue 通常用于防止 OverflowException 从具有较大范围 (（如 UInt16 或 Int32) ）转换为 Int16的数字类型。 该示例演示了此用法。
