字节数组的StringBuilder等价物

会的 MemoryStream 为你工作?接口可能不太方便,但它提供了一种简单的方法来附加字节,完成后,您可以将内容作为 byte[] ToArray() .

更多 StringBuilder

更新
扩展方法可能如下所示:

public static class MemoryStreamExtensions
{
    public static void Append(this MemoryStream stream, byte value)
    {
        stream.Append(new[] { value });
    }

    public static void Append(this MemoryStream stream, byte[] values)
    {
        stream.Write(values, 0, values.Length);
    }
}

MemoryStream stream = new MemoryStream();
stream.Append(67);
stream.Append(new byte[] { 68, 69 });
byte[] data = stream.ToArray();  // gets an array with bytes 67, 68 and 69

这个 MemoryStream 方法是好的,但是如果您想让类似StringBuilder的行为 BinaryWriter . BinaryWriter提供了您可能需要的所有写重写。

MemoryStream stream = new MemoryStream();
BinaryWriter writer = new BinaryWriter(stream);
writer.Write((byte)67);
writer.Write(new byte[] { 68, 69 });

可能 List<byte>

var byteList = new List<byte>();
byteList.Add(42);
byteList.AddRange(new byte[] { 1, 2, 3 });

List<byte> 然后当你想要它作为一个数组时,你可以调用 ToArray()

using System;
using System.IO;

public static class MemoryStreams
{
    public static MemoryStream Append(
        this MemoryStream stream
        , byte value
        , out bool done)
    {
        try
        {
            stream.WriteByte(value);
            done = true;
        }
        catch { done = false; }
        return stream;
    }

    public static MemoryStream Append(
        this MemoryStream stream
        , byte[] value
        , out bool done
        , uint offset = 0
        , Nullable<uint> count = null)
    {
        try
        {
            var rLenth = (uint)((value == null) ? 0 : value.Length);

            var rOffset = unchecked((int)(offset & 0x7FFFFFFF));

            var rCount = unchecked((int)((count ?? rLenth) & 0x7FFFFFFF));

            stream.Write(value, rOffset, rCount);
            done = true;
        }
        catch { done = false; }
        return stream;
    }
}
