如何在c#中将字节数组转换为HttpPostedFileBase图像文件？

using System.Web;
using System.Drawing;
using System.IO;

public class MyClass
{
    public HttpPostedFileBase ConvertByteArrayToImage(byte[] byteArray)
    {
        // 将字节数组转换为图像
        using (MemoryStream memoryStream = new MemoryStream(byteArray))
        {
            Image image = Image.FromStream(memoryStream);

            // 创建HttpPostedFileBase对象
            HttpPostedFileBase postedFile = new HttpPostedFileWrapper(new MemoryPostedFile(memoryStream, "image/jpeg"));

            return postedFile;
        }
    }
}

// 自定义MemoryPostedFile类，继承自HttpPostedFileBase
public class MemoryPostedFile : HttpPostedFileBase
{
    private readonly Stream _stream;
    private readonly string _contentType;

    public MemoryPostedFile(Stream stream, string contentType)
    {
        _stream = stream;
        _contentType = contentType;
    }

    public override int ContentLength => (int)_stream.Length;

    public override string ContentType => _contentType;

    public override Stream InputStream => _stream;
}
