Примеры
В следующем примере свойство используется MaxValue для предотвращения OverflowException преобразования в Int32 значение.The following example uses the MaxValue property to prevent an OverflowException when converting to an Int32 value.
using namespace System;
void main()
{
array<Int64>^ numbersToConvert = gcnew array<Int64> { 162345, 32183, -54000,
Int64::MaxValue/2 };
Int32 newNumber;
for each (Int64 number in numbersToConvert)
{
if ((number >= Int32::MinValue) && (number <= Int32::MaxValue))
{
newNumber = Convert::ToInt32(number);
Console::WriteLine("Successfully converted {0} to an Int32.",
newNumber);
}
else
{
Console::WriteLine("Unable to convert {0} to an Int32.", number);
}
}
}
// The example displays the following output to the console:
// Successfully converted 162345 to an Int32.
// Successfully converted 32183 to an Int32.
// Successfully converted -54000 to an Int32.
