.NET是否提供一种简单的方式将字节转换为KB，MB，GB等？

.NET是否提供一种简单的方式将字节转换为KB，MB，GB等？

这是一种相当简洁的方法：

static readonly string[] SizeSuffixes =         { "bytes", "KB", "MB", "GB", "TB", "PB", "EB", "ZB", "YB" };static string SizeSuffix(Int64 value, int decimalPlaces = 1){    if (decimalPlaces < 0) { throw new ArgumentOutOfRangeException("decimalPlaces"); }    if (value < 0) { return "-" + SizeSuffix(-value); }     if (value == 0) { return string.Format("{0:n" + decimalPlaces + "} bytes", 0); }    // mag is 0 for bytes, 1 for KB, 2, for MB, etc.    int mag = (int)Math.Log(value, 1024);    // 1L << (mag * 10) == 2 ^ (10 * mag)     // [i.e. the number of bytes in the unit corresponding to mag]    decimal adjustedSize = (decimal)value / (1L << (mag * 10));    // make adjustment when the value is large enough that    // it would round up to 1000 or more    if (Math.Round(adjustedSize, decimalPlaces) >= 1000)    {        mag += 1;        adjustedSize /= 1024;    }    return string.Format("{0:n" + decimalPlaces + "} {1}",         adjustedSize,         SizeSuffixes[mag]);}

这是我建议的原始实现，可能会稍慢一些，但易于遵循：

static readonly string[] SizeSuffixes =        { "bytes", "KB", "MB", "GB", "TB", "PB", "EB", "ZB", "YB" };static string SizeSuffix(Int64 value, int decimalPlaces = 1){    if (value < 0) { return "-" + SizeSuffix(-value); }    int i = 0;    decimal dValue = (decimal)value;    while (Math.Round(dValue, decimalPlaces) >= 1000)    {        dValue /= 1024;        i++;    }    return string.Format("{0:n" + decimalPlaces + "} {1}", dValue, SizeSuffixes[i]);}Console.WriteLine(SizeSuffix(100005000L));
