c# - 无法在 Image 类中找到 FromStream

Question

我有以下代码:

Image tmpimg = null;
HttpWebRequest httpWebRequest = (HttpWebRequest)HttpWebRequest.Create(url);
HttpWebResponse httpWebReponse = (HttpWebResponse)httpWebRequest.GetResponse();
Stream stream = httpWebReponse.GetResponseStream();
return Image.FromStream(stream);

在我输入 Image. 时的最后一行，FromStream 不在列表中。我能做什么？

Answer 1

使用和所需命名空间的更详细示例。

using System.Net;
using System.IO;
using System.Drawing;

public static Image GetImageFromUrl(string url)
    {
        HttpWebRequest httpWebRequest = (HttpWebRequest)HttpWebRequest.Create(url);
        
            using (HttpWebResponse httpWebReponse = (HttpWebResponse)httpWebRequest.GetResponse())
            {
                using (Stream stream = httpWebReponse.GetResponseStream())
                {
                    return Image.FromStream(stream);
                }
            }
    }
