如何把图片存储在mysql中

  引用如下命名空间：　　

  using System.Drawing;

using System.IO;

using System.Data.SqlClient;

设计数据库时，表中相应的字段类型为iamge

保存：

//图片路径

string strPath = this.FileUpload1.PostedFile.FileName.ToString ();

//读取图片

FileStream fs = new System.IO.FileStream(strPath, FileMode.Open, FileAccess.Read);

BinaryReader br = new BinaryReader(fs);

byte[] photo = br.ReadBytes((int)fs.Length);

br.Close();

fs.Close();

//存入

SqlConnection myConn = new SqlConnection("Data Source=.;Initial Catalog=stumanage;User ID=sa;Password=123");

string strComm = " INSERT INTO stuInfo(stuid,stuimage) VALUES(107,@photoBinary )";//操作数据库语句根据需要修改

SqlCommand myComm = new SqlCommand(strComm, myConn);

myComm.Parameters.Add("@photoBinary", SqlDbType.Binary, photo.Length);

myComm.Parameters["@photoBinary"].Value = photo;

myConn.Open();

if (myComm.ExecuteNonQuery() > 0)

{

   this.Label1.Text = "ok";

}

myConn.Close();

读取：

...连接数据库字符串省略

mycon.Open();

SqlCommand command = new

SqlCommand("select stuimage from stuInfo where stuid=107", mycon);//查询语句根据需要修改

byte[] image = (byte[])command.ExecuteScalar ();

//指定从数据库读取出来的图片的保存路径及名字

string strPath = "~/Upload/zhangsan.JPG";

string strPhotoPath = Server.MapPath(strPath);

//按上面的路径与名字保存图片文件

BinaryWriter bw = new BinaryWriter(File.Open(strPhotoPath,FileMode.OpenOrCreate));

bw.Write(image);

bw.Close();

//显示图片

this.Image1.ImageUrl = strPath;
