读取包含多个文件的 MemoryStream

List<MemoryStream> memoryStreams = new List<MemoryStream>();

// 添加多个 MemoryStream 对象
memoryStreams.Add(new MemoryStream(file1Bytes));
memoryStreams.Add(new MemoryStream(file2Bytes));

// 读取每个 MemoryStream 对象
foreach (MemoryStream memoryStream in memoryStreams)
{
    // 处理每个文件的内容
    memoryStream.Position = 0;
    using (StreamReader reader = new StreamReader(memoryStream))
    {
        string content = reader.ReadToEnd();
        // 处理文件内容
    }
}

MemoryStream memoryStream = new MemoryStream();

// 将多个文件的内容写入一个 MemoryStream 对象
memoryStream.Write(file1Bytes, 0, file1Bytes.Length);
memoryStream.Write(delimiterBytes, 0, delimiterBytes.Length);
memoryStream.Write(file2Bytes, 0, file2Bytes.Length);

// 读取 MemoryStream 对象中的文件内容
memoryStream.Position = 0;
using (StreamReader reader = new StreamReader(memoryStream))
{
    string file1Content = reader.ReadToEnd();
    // 处理第一个文件的内容

    // 跳过分隔符
    memoryStream.Seek(delimiterBytes.Length, SeekOrigin.Current);

    string file2Content = reader.ReadToEnd();
    // 处理第二个文件的内容
}
