存儲在SQL Server CE數據庫的C＃緊湊的框架代碼

Question

你好，我想插入圖片使用C＃Compact框架數據庫SQL CE影像..

我的代碼

FileInfo Filfo=New FileInfo(OpenFileDialog1.FileName.ToSting()); 
Long LngLength=5; 
FileStream fstrm=new FileStream(OpenFileDialog1.FileName.ToSting()); 
BinaryReader br=new BinaryReader(Fstrm); 
byte[] data=br.ReadBytes(int)lngLenght); 

string Query="insert into category(cm_id,cm_image) values(@id,@img)"; 
sqlcecommand cmd=new sqlcecommand(Query,cls.Connect()); 
cmd.parameters.add(new sqlcparameter("@id",(object)textbox1.text); 
cmd.parameters.add(new sqlcparameter("@id",(object)data); 
cmd.executenonquery(); 

但它顯示錯誤。 ... openfiledialog1，找不到文件....

我的負荷圖像的代碼

openfiledialog open=new opendailog(); 
open.filter="Image Files(*.jpg*bmp;|*.jpg;*bmp; 

if(open.showdilog()==dialogresult.Ok) 
{ 
    pitcherbox1.image=new bitmap(open.file); 
} 

Answer 1

從您的錯誤消息看，它看起來像過濾器無效。

在錯誤行儘量只*.jpg;*.bmp

FileInfo Filfo=New FileInfo(OpenFileDialog1.FileName.ToSting()); 
Long LngLength=5; 
FileStream fstrm=new FileStream(OpenFileDialog1.FileName.ToSting()); 
BinaryReader br=new BinaryReader(Fstrm); 
byte[] data=br.ReadBytes(int)lngLenght);  
string Query="insert into category(cm_id,cm_image) values(@id,@img)"; 
sqlcecommand cmd=new sqlcecommand(Query,cls.Connect()); 
cmd.parameters.add(new sqlcparameter("@id",(object)textbox1.text); 
cmd.parameters.add(new sqlcparameter("@img",(object)data); 
cmd.executenonquery();
