C# picturebox中的图像如何保存到数据库的image类型中？

引用：System.IO

MemoryStream ms = new MemoryStream()

pictureBox1.Image.Save(ms,System.Drawing.Imaging.ImageFormat.Jpeg)

byte[] img = ms.ToArray()

再将img写入数据库就行了。

读取img数据

byte[] curImg=rs["img"]

this.pictureBox1.Image=new Bitmap(new MemoryStream(img))

直接使用企业管理器好像没有办法 *** 作吧，通过软件或自己做个小软件读取。

#region//读取数据库中图片到内存.并显示

public void LoadToMemoryAndDisable(string serverAdress, string database)

{

//读取数据库中图片到内存.并显示

SqlConnection conn = new SqlConnection("server=" + serverAdress + "integrated security = sspidatabase = " + database)

SqlCommand cmd = new SqlCommand("select * from imgtable where imgname like '%bmp%'", conn)

conn.Open()

SqlDataReader dr

try

{

dr = cmd.ExecuteReader()

dr.Read()

System.Data.SqlTypes.SqlBinary sb = dr.GetSqlBinary(2)

//或byte[] imageData = (byte[])dr[2]

MemoryStream ms = new MemoryStream(sb.Value)//在内存中 *** 作图片数据

Bitmap bmp = new Bitmap(Bitmap.FromStream(ms))

this.pictureBox1.Image = bmp

dr.Close()

}

catch (Exception ex)

{

MessageBox.Show(ex.Message)

}

finally

{

conn.Close()

}

}

#endregion
