有一个 python 字节（来自 img），我如何在 C# 中处理它，并转换为字节 [] 或图像 stream？

Question

Now I got a python bytes like this: b'\x00\x00\x00\x00\x07\x80\x00\x03' , and it's from an image, how can I handle it in C#, and convert to a byte[ ] and then return it as a Bitmap ?

Here is my Python code:

fig = plt.figure() 
canvas = fig.canvas buffer = io.BytesIO() 
canvas.print_png(buffer) 
bin_data = buffer.getValue() 
buffer.close() 

#Excuting reults like this:
bin_data : b'\x00\x00\x00\x00\x07\x80\x00\x03'  # just a sample 
list(bin_data) :[0, 0, 0, 0, 7, 128, 0, 3] # sample 

Is there any way to handle it in C#(client) and transform bin_data/list(bin_data) to a C# byte[] or an image Stream?

Answer 1

There are a few ways to do this. The easiest is probably to save the bytes to a file, then load that file in C# with something like ReadAllBytes .

In Python you can save the bytes by opening a file in binary mode, then writing the bytes:

f = open("my_file_name.bin", "wb")
f.write(bin_data)

Then you could use Python's subprocess to invoke your C# application, or follow along here if you want to integrate your C# code directly into your Python application.
