示例1: catch
NumberStyles style;
CultureInfo culture;
string value;
byte number;
// Parse number with decimals.
// NumberStyles.Float includes NumberStyles.AllowDecimalPoint.
style = NumberStyles.Float;
culture = CultureInfo.CreateSpecificCulture("fr-FR");
value = "12,000";
number = Byte.Parse(value, style, culture);
Console.WriteLine("Converted '{0}' to {1}.", value, number);
culture = CultureInfo.CreateSpecificCulture("en-GB");
try
{
number = Byte.Parse(value, style, culture);
Console.WriteLine("Converted '{0}' to {1}.", value, number);
}
catch (FormatException) {
Console.WriteLine("Unable to parse '{0}'.", value); }
value = "12.000";
number = Byte.Parse(value, style, culture);
Console.WriteLine("Converted '{0}' to {1}.", value, number);輸出：
Converted '12,000' to 12. Unable to parse '12,000'. Converted '12.000' to 12.
示例2: catch
string value;
NumberStyles style;
byte number;
// Parse value with no styles allowed.
style = NumberStyles.None;
value = " 241 ";
try
{
number = Byte.Parse(value, style);
Console.WriteLine("Converted '{0}' to {1}.", value, number);
}
catch (FormatException) {
Console.WriteLine("Unable to parse '{0}'.", value); }
// Parse value with trailing sign.
style = NumberStyles.Integer | NumberStyles.AllowTrailingSign;
value = " 163+";
number = Byte.Parse(value, style);
Console.WriteLine("Converted '{0}' to {1}.", value, number);
// Parse value with leading sign.
value = " +253 ";
number = Byte.Parse(value, style);
Console.WriteLine("Converted '{0}' to {1}.", value, number);
// This example displays the following output to the console:
// Unable to parse ' 241 '.
// Converted ' 163+' to 163.
// Converted ' +253 ' to 253.示例3:
string stringToConvert = " 162";
byte byteValue;
try
{
byteValue = Byte.Parse(stringToConvert);
Console.WriteLine("Converted '{0}' to {1}.", stringToConvert, byteValue);
}
catch (FormatException)
{
Console.WriteLine("Unable to parse '{0}'.", stringToConvert);
}
catch (OverflowException)
{
Console.WriteLine("'{0}' is greater than {1} or less than {2}.",
stringToConvert, Byte.MaxValue, Byte.MinValue);
}輸出：
Converted ' 162' to 162.
示例4: catch
string stringToConvert;
byte byteValue;
stringToConvert = " 214 ";
try {
byteValue = Byte.Parse(stringToConvert, CultureInfo.InvariantCulture);
Console.WriteLine("Converted '{0}' to {1}.", stringToConvert, byteValue);
}
catch (FormatException) {
Console.WriteLine("Unable to parse '{0}'.", stringToConvert); }
catch (OverflowException) {
Console.WriteLine("'{0}' is greater than {1} or less than {2}.",
stringToConvert, Byte.MaxValue, Byte.MinValue); }
stringToConvert = " + 214 ";
try {
byteValue = Byte.Parse(stringToConvert, CultureInfo.InvariantCulture);
Console.WriteLine("Converted '{0}' to {1}.", stringToConvert, byteValue);
}
catch (FormatException) {
Console.WriteLine("Unable to parse '{0}'.", stringToConvert); }
catch (OverflowException) {
Console.WriteLine("'{0}' is greater than {1} or less than {2}.",
stringToConvert, Byte.MaxValue, Byte.MinValue); }
stringToConvert = " +214 ";
try {
byteValue = Byte.Parse(stringToConvert, CultureInfo.InvariantCulture);
Console.WriteLine("Converted '{0}' to {1}.", stringToConvert, byteValue);
}
catch (FormatException) {
Console.WriteLine("Unable to parse '{0}'.", stringToConvert); }
catch (OverflowException) {
Console.WriteLine("'{0}' is greater than {1} or less than {2}.",
stringToConvert, Byte.MaxValue, Byte.MinValue); }輸出：
Converted ' 214 ' to 214. Unable to parse ' + 214 '. Converted ' +214 ' to 214.
