推荐答案

如果您希望将其存储在MemoryStream中，则可以尝试

If you wish to have it stored in a MemoryStream you could try

List<MemoryStream> list = new List<MemoryStream>();
string[] fileNames = Directory.GetFiles("Path");
for (int iFile = 0; iFile < fileNames.Length; iFile++)
{
    using (FileStream fs = new FileStream(fileNames[iFile], FileMode.Open))
    {
        byte[] b = new byte[fs.Length];
        fs.Read(b, 0, (int)fs.Length);
        list.Add(new MemoryStream(b));
    }
}

如果您希望将文件名保留为键，甚至可以使用词典

Or even use a Dictionary if you wish to keep the file names as keys

Dictionary<string, MemoryStream> files = new Dictionary<string, MemoryStream>();
string[] fileNames = Directory.GetFiles("Path");
for (int iFile = 0; iFile < fileNames.Length; iFile++)
{
    using (FileStream fs = new FileStream(fileNames[iFile], FileMode.Open))
    {
        byte[] b = new byte[fs.Length];
        fs.Read(b, 0, (int)fs.Length);
        files.Add(Path.GetFileName(fileNames[iFile]), new MemoryStream(b));
    }
}
