ToSingle(Char) 呼叫這個方法一律會擲回 InvalidCastException。 ToSingle(Byte) 將指定之 8 位元不帶正負號的整數值,轉換為相等的單精確度浮點數。 ToSingle(Boolean) 將指定的布林值轉換為相等的單精確度浮點數。 ToSingle(Int64) 將指定之 64 位元帶正負號
using System; public class Example { public static void Main() { String[] values = { null, "", "0xC9", "C9", "101", "16.3", "$12", "$12.01", "-4", "1,032", "255", " 16 " }; foreach (var value in values) { try { byte number = Convert.ToByte(value); Console....
byte sourceNumber = byte.MaxValue; bool isSigned = Math.Sign(Convert.ToDouble(sourceNumber.GetType().GetField("MinValue").GetValue(null))) == -1; string value = Convert.ToString(sourceNumber, 16); sbyte targetNumber; try { targetNumber = Convert.ToSByte(value, 16); if (! isSigned ...

ToSingle(Char) 调用此方法始终引发 InvalidCastException。 ToSingle(Byte) 将指定的 8 位无符号整数的值转换为等效的单精度浮点数。 ToSingle(Boolean) 将指定的布尔值转换为等效的单精度浮点数。 ToSingle(Int64) 将指定的 64 位带符号整数的值转换为等效的单精度浮点数。To...
value 大于Byte.MaxValue。 示例 以下示例将无符号 16 位整数数组转换为 Byte 值。 C# 复制 运行 ushort[] numbers = { UInt16.MinValue, 121, 340, UInt16.MaxValue }; byte result; foreach (ushort number in numbers) { try { result = Convert.ToByte(number); Console.WriteLine("Converted the...
public static short ToInt16 (float value); 参数 value Single 要转换的单精度浮点数。 返回 Int16 value,舍入为最接近的 16 位带符号整数。 如果 value 为两个整数中间的数字,则返回二者中的偶数;即 4.5 转换为 4,而 5.5 转换为 6。 例外 OverflowException value 大于Int16.MaxValue 或小于 Int16...
