sql中image數據列存取

c#的代碼 用二進制流讀取文件 Stream ImgdataStream = this.txtFile.PostedFile.InputStream; int ImgdataLen = this.txtFile.PostedFile.ContentLength; byte[] Imgdata = new byte[ImgdataLen]; //文件信息 ImgdataStream.Read( Imgdata,0,ImgdataLen ); ArrayFileName = ImgdataFileName.Split( '// ' ); PasteName = ArrayFileName.GetValue( ArrayFileName.Length - 1 ).ToString().Trim(); ImageID = this.GetMaxImageID(); //保存圖片 string sqlPic = "Insert Into ImageStore(ID,editionnum,issue,articlenum,imgdata) values( "+ ImageID + ", "+ this.EditionNum + ", "+ this.IssueNum + ", "+ this.ArticleNum + ",@imgdata) "; SqlParameter paraImgData = new SqlParameter( "@imgdata ",SqlDbType.Image ); paraImgData.Value = Imgdata; SqlConnection conn = new SqlConnection( strConnection ); SqlCommand cmd = new SqlCommand( sqlPic,conn ); cmd.Parameters.Add( paraImgData ); conn.Open(); cmd.ExecuteNonQuery(); conn.Close();
