推荐答案

下载文件docx或pdf您可以在数据库中使用二进制数据类型。将文件数据和文件名分别存储在两列中。将文件数据作为字节。 C＃有一种从文件中获取字节的方法：



File.ReadAllBytes [ ^ ]



获取字节数组并将其写入文件数据列。将文件名存储在另一列中。



当您将其读回时，只需在将字节输入字节数组后使用以下方法：



档案.WriteAllBytes [ ^ ]

You can probably make use of binary data type in your database. Store your file data and file name separately in two columns. Have file data as bytes. C# has a way to get bytes from a file:

File.ReadAllBytes[^]

Get the byte array and write it to the file data column. Store the file name in another column.

When you read it back, simply use the following method after getting the bytes into a byte array:

File.WriteAllBytes[^]

我使用了以下帮助。这真的对我有用。我希望这对你也有帮助。
