推荐答案

您如何检索Firebird的代码?如果要获取数据并将其转换为字节[]，请尝试:

How are you retrieving the code form Firebird? If you are getting the data and casting it to a byte[] try:

byte [] blob = row["image"];
// create a file FileStream to write the data
FileStream fs = new FileStream("image.jpg", FileMode.Create); 
fs.Write(blob,0,blob.Length);
fs.Close();

上面的代码应该可以解决问题.

The above code should do the trick.

PS:我在代码中做了很多假设，但是您可以理解.

PS: I have made lots of assumption in the code, but you can get the idea.
