[c#]asp.net (c#) 图片存取 access 数据库

Stream fileDataStream = this.FileUpload1.PostedFile.InputStream;

byte[] fileData = new byte[fileDataStream.Length];

fileDataStream.Read(fileData, 0, fileData.Length);//读取流内容

fileDataStream.Seek(0, SeekOrigin.Begin);//设置流的位置

上面代码图片二进制流获取成功

下面是在Access数据库中保存二进制流，需要把保存二进制流字段设置为“OLE对象”类型

string strConn = string.Format("Provider=Microsoft.Jet.OLEDB.4.0;Data Source = {0}", Application.StartupPath + "\\Test.mdb");

OleDbConnection Conn = new OleDbConnection(strConn);

OleDbCommand cmd = new OleDbCommand();

cmd.Connection = Conn;

cmd.CommandText = "insert into pic (img) values(@img)";

cmd.Parameters.Add("@img", OleDbType.Binary, Convert.ToInt32(fileData.Length)).Value = fileData;

Conn.Open();

cmd.ExecuteNonQuery();

cmd.Dispose();

Conn.Close();

Conn.Dispose();
