请教一个问题, C# 如何将 textBox中的输入的浮点数保存到byte 型的数组里面呢?
rt 如果是String形式的话可以ToCharArray 我是想回复【1楼】yajira
如果是string形式的话
可以tochararray

谢谢回复!
我是想把浮点数拆分为4个字节,不知道有没有方法呢 回复【1楼】yajira

可以tochararray

C#内的CHAR不是一个BYTE吧? // Example of the BitConverter.GetBytes( double ) method.
//http://msdn.microsoft.com/zh-cn/library/a5be4sc9.aspx
using System;
class GetBytesDoubleDemo
{
const string formatter = "{0,25:E16}{1,30}";
// Convert a double argument to a byte array and display it.
public static void GetBytesDouble( double argument )
{
byte[ ] byteArray = BitConverter.GetBytes( argument );
Console.WriteLine( formatter, argument,
BitConverter.ToString( byteArray ) );
}
public static void Main( )
{
Console.WriteLine(
"This example of the BitConverter.GetBytes( double ) " +
"\nmethod generates the following output.\n" );
Console.WriteLine( formatter, "double", "byte array" );
Console.WriteLine( formatter, "------", "----------" );
// Convert double values and display the results.
GetBytesDouble( 0.0 );
GetBytesDouble( 1.0 );
GetBytesDouble( 255.0 );
GetBytesDouble( 4294967295.0 );
GetBytesDouble( 0.00390625 );
GetBytesDouble( 0.00000000023283064365386962890625 );
GetBytesDouble( 1.23456789012345E-300 );
GetBytesDouble( 1.2345678901234565 );
GetBytesDouble( 1.2345678901234567 );
GetBytesDouble( 1.2345678901234569 );
GetBytesDouble( 1.23456789012345678E+300 );
GetBytesDouble( double.MinValue );
GetBytesDouble( double.MaxValue );
GetBytesDouble( double.Epsilon );
GetBytesDouble( double.NaN );
GetBytesDouble( double.NegativeInfinity );
GetBytesDouble( double.PositiveInfinity );
}
}
