Question

我有一个包含文件列表的路径。

foreach (var file in Directory.GetFiles(networkpath))
{
  Stream s=file.
}

我想将文件转换为Stream.How继续进行？

Answer 1

这是你需要的吗？

foreach (var file in Directory.GetFiles(networkpath))
{
    using (FileStream fs = File.Open(file, FileMode.Open))
    {

    }
}

您可以使用C＃中的FileStream安全地读取文件。为了确保正确读取整个文件，您应该在循环中调用FileStream.Read方法，即使在大多数情况下，只需要在FileStream.Read方法的单个调用中读取整个文件。

首先创建FileStream以打开文件进行读取。然后在循环中调用FileStream.Read，直到读取整个文件。最后关闭流。

using System.IO;

public static byte[] ReadFile(string filePath)
{
   byte[] buffer;
   FileStream fileStream = new FileStream(filePath,         FileMode.Open, FileAccess.Read);
      try
     {
        int length = (int)fileStream.Length;  // get file length
       buffer = new byte[length];            // create buffer
        int count;                            // actual number of bytes read
        int sum = 0;                          // total number of bytes read

        // read until Read method returns 0 (end of the stream has been reached)
       while ((count = fileStream.Read(buffer, sum, length - sum)) > 0)
       sum += count;  // sum is a buffer offset for next reading
     }
     finally
     {
         fileStream.Close();
     }
     return buffer;
}

更改您的文件路径以适合您的代码！在循环中添加它！

FileStream fStream = new FileStream(@"c:\file.txt", FileMode.Open);
try
 {
  // read from file or write to file
 }
finally
 {
   fStream.Close();
  }

将文件转换为流
