从C#NET 中的byte []保存文件

using System.IO;

byte[] fileBytes = ...; // 从其他地方获取byte[]
string filePath = "path/to/save/file.ext";

using (FileStream fs = new FileStream(filePath, FileMode.Create))
{
    fs.Write(fileBytes, 0, fileBytes.Length);
}

using System.IO;

byte[] fileBytes = ...; // 从其他地方获取byte[]
string filePath = "path/to/save/file.ext";

File.WriteAllBytes(filePath, fileBytes);

using System.IO;

byte[] fileBytes = ...; // 从其他地方获取byte[]
string filePath = "path/to/save/file.ext";

using (BinaryWriter bw = new BinaryWriter(File.Open(filePath, FileMode.Create)))
{
    bw.Write(fileBytes);
}
