vb.net字节数组到文本文件并返回 [英] vb.net Byte Array to text file and back

问题描述

大家好，

我正在尝试将图像保存在文本文件中.

这是我在做什么:

Hello Everyone,

I am trying to save an image in a text file.

here is what I am doing:

Dim writer As New System.IO.StreamWriter("D:\Object.txt", True)

Dim temp() As Byte = convertImageToBytes(i.setBitmap)

Dim str = System.Text.Encoding.ASCII.GetString(temp)
writer.WriteLine(str)

我得到了温度(字节数组)的计数并记下来.

接下来，当我想读取该数组时，我使用:

I get the count of the temp (byte array) and note it down.

next when I want to read that array, i use:

Dim byteArray() As Byte
        byteArray = System.Text.Encoding.ASCII.GetBytes(reader.ReadLine.ToString)
Dim b As Bitmap = imgConverter.ConvertFrom(byteArray)

这里的数目也一样.

但是当我将字节数组转换为图像时，我得到了一个大十字架！！！

可能是什么问题?

另外，我想在对象的属性中输入名称，位置等文字.
例如:

名称:Name1
X:500
Y:50
尺码X:200
尺码Y:600
BYTE ARRAY HERE
zVal:5
等



有人可以帮我将图像数据写入文本文件吗?

在此先感谢!!!

here also the count is same.

but when I convert the byte array to image, I get a Big Cross!!!

What could be the problem?

Also, I would like to put in my object''s properties in text like name, location, etc.
eg:

Name: Name1
X:500
Y:50
SizeX:200
SizeY:600
BYTE ARRAY HERE
zVal:5
etc



Can someone help me in writing the image data to a text file?

Thanks in Advance!!!

推荐答案

请使用 ^ ]的Write(Byte [])方法写入图像，反之 BinaryReader [^ ]的ReadBytes(int count)方法将其读回.在这种情况下，将字节数组编码为ASCII并不是您真正想要的.

问候，

—曼弗雷德(Manfred)

Please use the BinaryWriter[^]''s Write(Byte[]) method to write the image and conversely the BinaryReader[^]''s ReadBytes(int count) method to read it back in. Encoding a byte array into ASCII is not really what you want to do in this case.

Regards,

— Manfred
