示例1:
int int1 = 128;
try {
byte value1 = (byte) int1;
Console.WriteLine(value1);
}
catch (OverflowException) {
Console.WriteLine("{0} is out of range of a byte.", int1);
}
double dbl2 = 3.997;
try {
byte value2 = (byte) dbl2;
Console.WriteLine(value2);
}
catch (OverflowException) {
Console.WriteLine("{0} is out of range of a byte.", dbl2);
}輸出：
128 3
示例2: foreach
int[] numbers = { Int32.MinValue, -1, 0, 121, 340, Int32.MaxValue };
byte result;
foreach (int number in numbers)
{
try {
result = Convert.ToByte(number);
Console.WriteLine("Converted the {0} value {1} to the {2} value {3}.",
number.GetType().Name, number,
result.GetType().Name, result);
}
catch (OverflowException) {
Console.WriteLine("The {0} value {1} is outside the range of the Byte type.",
number.GetType().Name, number);
}
}輸出：
The Int32 value -2147483648 is outside the range of the Byte type. The Int32 value -1 is outside the range of the Byte type. Converted the Int32 value 0 to the Byte value 0. Converted the Int32 value 121 to the Byte value 121. The Int32 value 340 is outside the range of the Byte type. The Int32 value 2147483647 is outside the range of the Byte type.
示例3: catch
string string1 = "244";
try {
byte byte1 = Byte.Parse(string1);
Console.WriteLine(byte1);
}
catch (OverflowException) {
Console.WriteLine("'{0}' is out of range of a byte.", string1);
}
catch (FormatException) {
Console.WriteLine("'{0}' is out of range of a byte.", string1);
}
string string2 = "F9";
try {
byte byte2 = Byte.Parse(string2,
System.Globalization.NumberStyles.HexNumber);
Console.WriteLine(byte2);
}
catch (OverflowException) {
Console.WriteLine("'{0}' is out of range of a byte.", string2);
}
catch (FormatException) {
Console.WriteLine("'{0}' is out of range of a byte.", string2);
}
// The example displays the following output:
// 244
// 249示例4:
byte[] numbers = { 0, 16, 104, 213 };
foreach (byte number in numbers) {
// Display value using default formatting.
Console.Write("{0,-3} --> ", number.ToString());
// Display value with 3 digits and leading zeros.
Console.Write(number.ToString("D3") + " ");
// Display value with hexadecimal.
Console.Write(number.ToString("X2") + " ");
// Display value with four hexadecimal digits.
Console.WriteLine(number.ToString("X4"));
}輸出：
0 --> 000 00 0000 16 --> 016 10 0010 104 --> 104 68 0068 213 --> 213 D5 00D5
示例5:
byte[] numbers ={ 0, 16, 104, 213 };
Console.WriteLine("{0} {1,8} {2,5} {3,5}",
"Value", "Binary", "Octal", "Hex");
foreach (byte number in numbers) {
Console.WriteLine("{0,5} {1,8} {2,5} {3,5}",
number, Convert.ToString(number, 2),
Convert.ToString(number, 8),
Convert.ToString(number, 16));
}輸出：
