[英]storing image to byte[] into Mysql using asp.net and c#
I am using Asp.net with C#
and back-end MySql
to keep Images as byte[] array
with using BLOB datatype
我正在使用
Asp.net with C#
和后端MySql
Asp.net with C#
并使用BLOB datatype
将Images as byte[] array
保留Images as byte[] array
TABLE : ImageLog
ImgID int (auto increment)
ImageLogo blob
I am using following function to convert image to array...
我正在使用以下
function to convert image to array...
private byte[] ConvertImageToByteArray(FileUpload fuImgToByte)
{
byte[] ImageByteArray;
try
{
MemoryStream ms = new MemoryStream(fuImgToByte.FileBytes);
ImageByteArray = ms.ToArray();
return ImageByteArray;
}
catch (Exception ex)
{
return null;
}
}
here is calling method for creating byte[] bt
to insert into MySql
这是用于创建要插入
MySql
byte[] bt
调用方法
Byte[] bt = null;
bt = ConvertImageToByteArray(FileUploader1); --> Passing File Uploader ControlID
inserting like... 像...插入
INSERT INTO IMAGELOG (ImageLogo) VALUES ('"+bt+"')
; INSERT INTO IMAGELOG (ImageLogo) VALUES ('"+bt+"')
;
Now, Program runs perfectlly without causing any errors but when image stored into MySql, it stored like System.Byte[] not into byte[] array
. 现在,Program可以完美运行,不会引起任何错误,但是当映像存储在MySql中时,
it stored like System.Byte[] not into byte[] array
。 Result Something like this... 结果像这样...
ImgID ImageLogo

Please tell me is it in proper format ? 请告诉我格式正确吗? ?
? or not ??
或不 ?? Every suggestions are welcome.
欢迎提出任何建议。 Thanks in advance
提前致谢
Problem Solved After Lot's of Difficulties... Simply Add Parameters With ?
解决了很多难题之后...用
?
轻松添加参数 instead passing byte array bt
directly within Insert Query...Something like this: 而是直接在Insert Query中传递字节数组
bt
...
INSERT INTO IMAGELOG (ImageLogo) VALUES (?p1)
and Pass values something like this INSERT INTO IMAGELOG (ImageLogo) VALUES (?p1)
并传递类似以下的值
cmd.Parameters.Add("?p1", bt); cmd.Parameters.Add(“?p1”,bt); <-- Adding parameter p1 value here
<-在此处添加参数p1值
Note: If you are using MySql
as database end then i suggest to use ?
注意:如果您使用
MySql
作为数据库端,那么我建议使用?
instead @
symbol. 而是
@
符号。
OUTPUT:
ImgID ImageLogo
