Drawing.Imaging; public class BitmapToMemoryStream { public static void Main() { Bitmap bitmap = new Bitmap("example.bmp"); MemoryStream memoryStream = new MemoryStream(); bitmap.Save(memoryStream, ImageFormat.Bmp); // 在这里,您可以使用memoryStream进行其他操作,例如将其上传到云存储服务。
The following example demonstrates how to save a bitmap image to a file stream by using the derivedTiffBitmapEncoderclass. C# FileStream stream =newFileStream("empty.tif", FileMode.Create); TiffBitmapEncoder encoder =newTiffBitmapEncoder(); TextBlock myTextBlock =newTextBlock(); myText...

Save(Stream, ImageCodecInfo, EncoderParameters) 使用指定的编码器和图像编码器参数,将该图像保存到指定的流。 (继承自Image) Save(Stream, ImageFormat) 将此图像以指定的格式保存到指定的流中。 (继承自Image) Save(String) 将该Image保存到指定的文件或流。

For that you need to use one of the overloaded Save methods of the Bitmap class. I was trying to use this one:[C#] public void Save(Stream, ImageCodecInfo, EncoderParameters);I found some sample code that looked like it was what I wanted: ...
