c# - ImageResizer 错误

Question

我正在使用图像调整器 imageresizing.net。但是，当我尝试上传或调整图像大小时，出现错误:

The source stream is at the end (have you already read it?). You must call stream.Seek(0, SeekOrigin.Begin); before re-using a stream, or use ImageJob with ResetSourceStream=true the first time the stream is read.

using (Stream newFile =  System.IO.File.Create(Path.Combine(_pathResolver.ResolvePath(_appSettings.CompanyLogosDirectory), newFileName)) )
{
     //newFile.Seek(0, SeekOrigin.Begin);

     ImageResizer.ImageJob i = new ImageJob();
     //i.ResetSourceStream = true;
     i = new ImageResizer.ImageJob(logo.InputStream, newFile, new ImageResizer.ResizeSettings("width=120;height=45;format=jpg;mode=max"));

     i.CreateParentDirectory = false; //Auto-create the uploads directory.
     i.Build();
}

Answer 1

您在提供代码之前使用了 logo.InputStream(可能用于其他工作)。您可以再次阅读图像或作为异常建议在 using 语句之前放在代码下方:

logo.InputStream.Seek(0, SeekOrigin.Begin);
