Save byte array to file [duplicate]

问题

This question already has answers here:

Can a Byte[] Array be written to a file in C#? (8 answers)

Closed 6 years ago.

I have a byte array (an IEnumerable actually), and I need to save it to a new file containing this data.

How do I do that?

I found some answers telling how to create a MemoryStream from that, but still can't save it to a brand new file.

回答1:

You can use:

File.WriteAllBytes("Foo.txt", arrBytes); // Requires System.IO

If you have an enumerable and not an array, you can use:

File.WriteAllBytes("Foo.txt", arrBytes.ToArray()); // Requires System.Linq

回答2:

You can use File.WriteAllBytes
