Folder file traversal and insertion of database operations, recursive operation of IO Directory files

When we manage the content management system, the data volume is large, the dependence on the machine is relatively strong, for example, I want to upload a folder of many images uploaded to the site, uploading it will take a long time, I think of walking through the folder to get the file name, and the path and file saved to the corresponding field in the database.

The following two examples are written,

usingSystem;usingSystem.Collections.Generic;usingSystem.Data;usingSystem.Data.SqlClient;usingSystem.IO;usingSystem.Linq;usingSystem.Text;usingSystem.Threading.Tasks;namespaceconsoleapplication1{classProgram {/// <summary>        ///Open Connection/// </summary>             Static voidMain (string[] args) {            stringDIRP =@"C:\Users\sihang\Desktop\ Boao Photo"; DirectoryInfo Mydir=NewDirectoryInfo (DIRP); StringBuilder SB=NewStringBuilder (); foreach(FileInfo fiinchMydir. GetFiles ()) {stringThumbimg ="/uploadfiles/article/150403/"+fi.                Name; stringtitle = (FI. Name). Substring (0, FI. Name.lastindexof (".")); stringDate = DateTime.Now.ToString ("YYYY-MM-DD HH:mm:ss"); stringweb ="Xinhua"; stringInfoimg ="/uploadfiles/article/150403/"+fi.                Name; //Console.WriteLine (thumbimg); //Console.WriteLine (title); //Console.WriteLine (date); //Console.WriteLine (web); //Console.WriteLine (infoimg); //Console.WriteLine ("/uploadfiles/article/150403/" + fi.                Name); //Console.WriteLine (FI. Name). Substring (0, Fi.                Name.lastindexof ("."))); //Console.WriteLine (DateTime.Now.ToString ("Yyyy-mm-dd HH:mm:ss")); //Console.WriteLine ("Xinhua"); //SD + = "INSERT into cc;";Sb. Append ("INSERT INTO Jcms_normal_content (img,title,adddate,customfield05,customfield04,channelid,classid,ispass,isimg , Readgroup,module,templateid) VALUES ('"+ thumbimg +"', '"+ title +"', '"+ Date +"', '"+ Web +"', '"+ infoimg +"' , ' 2 ', ' A ', ' 1 ', ' 1 ', '-1 ', ' picture ', ' 1011 '); \ r \ n"); } Console.WriteLine (sb.)            ToString ()); //console.readline ();        }    }}

This is the desktop on the photo of Boao photos in the folder of all the picture path and picture name as a title to the corresponding field, and the SQL script output to the CMD window.

Example 2:

usingSystem;usingSystem.Collections.Generic;usingSystem.ComponentModel;usingSystem.Data;usingSystem.Drawing;usingSystem.Linq;usingSystem.Text;usingSystem.Windows.Forms;usingSystem.IO;namespacewindowsformsapplication1{ Public Partial classForm1:form { PublicForm1 () {InitializeComponent (); }        Private voidButton1_Click (Objectsender, EventArgs e) {            stringDirv =@"D:\video\ysxs"; DirectoryInfo Mydir=NewDirectoryInfo (DIRV); StringBuilder SB=NewStringBuilder (); foreach(FileInfo fiinchMydir. GetFiles ()) {stringtitle = (FI. Name). Substring (0, FI. Name.lastindexof (".")); stringDate = DateTime.Now.ToString ("YYYY-MM-DD HH:mm:ss"); //notation 1                stringfilepath =@"D:\video\ysxs"+fi.                Name; Sb. Append ("INSERT INTO jcms_normal_content (Title,adddate,classid,editor,ispass,readgroup,module,templateid, CUSTOMFIELD01) VALUES ('"+ title +"', '"+ Date +"' , ' 8 ', ' admin ', ' 1 ', '-1 ', ' News ', ' one ', '"+ filepath +"'); \ r \ n"); TextBox1.Text=sb.                ToString (); //notation 2//string s = @ "INSERT into jcms_normal_content ((Title,adddate,classid,editor,ispass,readgroup,module,templateid,                CUSTOMFIELD01) VALUES (' {0} ', ' "+ Date +" ', ' 8 ', ' admin ', ' 1 ', '-1 ', ' News ', ' one ', ' d:\\video\\ysxs\\{1} '); "; //TextBox1.Text + = string. Format (S, fi. Name.replace (". txt", ""), FI. Name) + "\ r \ n";             }        }    }}

Create a new WinForm console program so that you can output SQL to the TextBox1 text box.
