在c＃.net中的sqlserver中保存和检索指纹文件（.fpt） [英] saving and retrieving finger print files(.fpt) in sqlserver in c#.net

问题描述

请指导我如何在sql server中存储指纹文件，然后检索该文件。

这是一个代码

用于保存文件..

SaveFileDialog save = new SaveFileDialog（）;

save.Filter =指纹模板文件（* .fpt）| * .fpt;

if（save.ShowDialog（）== DialogResult.OK）{

using（FileStream fs = File.Open（save.FileName，FileMode.Create，FileAccess.Write））{

Template.Serialize（fs）;



用于加载文件..



OpenFileDialog open = new OpenFileDialog（）;

open.Filter =指纹模板文件（* .fpt）| * .fpt;

if（ open.ShowDialog（）== DialogResult.OK）{

using（FileStream fs = File.OpenRead（open.FileName））{

DPFP.Template template = new DPFP 。模板（fs）;

OnTemplate（模板）;

}

推荐答案

已经回答了这个问题这里 [ ^ ]。

This was already answered here[^].

以字节为单位转换并保存sql server中的bites $ / b $ b $ MemoryStream fingerprintData = new MemoryStream（）;

Template.Serialize（fingerprintData）;

fingerprintData.Position = 0;

BinaryReader br = new BinaryReader（fingerprintData） ;

Byte [] bytes = br.ReadBytes（（Int32）fingerprintData.Length）;

convert it in bytes and save the bites in sql server
MemoryStream fingerprintData = new MemoryStream();
Template.Serialize(fingerprintData);
fingerprintData.Position = 0;
BinaryReader br = new BinaryReader(fingerprintData);
Byte[] bytes = br.ReadBytes((Int32)fingerprintData.Length);
