Question

I am trying to convert a decimal to an integer safely.

Something like

public static bool Decimal.TryConvertToInt32(decimal val, out int val)

this will return false if it cannot convert to an integer, and true w/ successful output if it can.

This is to avoid catching the OverflowException in decimal.ToInt32 method. What is the easiest way to do this?

Answer 1

Here:

public static bool TryConvertToInt32(decimal val, out int intval)
{
    if (val > int.MaxValue || val < int.MinValue)
    {
      intval = 0; // assignment required for out parameter
      return false;
    }

    intval = Decimal.ToInt32(val);

    return true;
}
