如何在C#中将 struct System.Byte byte[]转换为System.IO.Stream对象？

Answer 1

将字节数组转换为流的最简单方法是使用MemoryStream类：

Stream stream = new MemoryStream(byteArray);

Answer 2

You're looking for the MemoryStream.Write method .

For example, the following code will write the contents of a byte[] array into a memory stream:

byte[] myByteArray = new byte[10];
MemoryStream stream = new MemoryStream();
stream.Write(myByteArray, 0, myByteArray.Length);

Alternatively, you could create a new , non-resizable MemoryStream object based on the byte array:

byte[] myByteArray = new byte[10];
MemoryStream stream = new MemoryStream(myByteArray);

Answer 3

The general approach to write to any stream (not only MemoryStream ) is to use BinaryWriter :

static void Write(Stream s, Byte[] bytes)
{
    using (var writer = new BinaryWriter(s))
    {
        writer.Write(bytes);
    }
}

Answer 4

查看MemoryStream类。

Answer 5

If you are getting an error with the other MemoryStream examples here, then you need to set the Position to 0.

public static Stream ToStream(this bytes[] bytes) 
{
    return new MemoryStream(bytes) 
    {
        Position = 0
    };
}
