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));
}
}
