ASP. NET Excel Data Import Database

Today, I have made such a project, and I need to import the Excel data to the database. Although I have written it before, I forgot it. So today I found a better one to collect it.

 

Below isCode:

 

Protected   Void Btnimport_click ( Object Sender, eventargs E)
{
If (Fileupload1.hasfile =   False ) // Hasfile is used to check whether a specified file exists in fileupload.
{
Response. Write ( " <SCRIPT> alert ('select an Excel file') </SCRIPT> " );
Return ; // If no file exists
}
String Isxls = System. Io. Path. getextension (fileupload1.filename). tostring (). tolower (); // System. Io. Path. getextension get the file extension
If (Isxls ! =   " . Xls " )
{
Response. Write ( " <SCRIPT> alert ('only Excel file' can be selected) </SCRIPT> " );
Return ; // If the selected file is not an Excel file
}
String Filename = Fileupload1.filename; // Obtain the datetime date function of the execle file name
String Savepath = Server. mappath (( " Upfiles \\ " ) + Filename ); // Server. mappath
Fileupload1.saveas (savepath ); // Saveas saves the uploaded file content on the server
Dataset DS = Excelsqlconnection (savepath, filename ); // Call a custom Method
Datarow [] Dr = DS. Tables [ 0 ]. Select (); // Define a datarow Array
Int Rowsnum = DS. Tables [ 0 ]. Rows. count;
If (Rowsnum =   0 )
{
Response. Write ( " <SCRIPT> alert ('excel table is empty, no data! ') </SCRIPT> " ); // Prompt the user when the Excel table is empty
}
Else
{
For ( Int I =   0 ; I < Dr. length; I ++ )
{
// Except for creating a folder named "upfiles", you don't need to worry about it. You just need to obtain the Excel value in the following way, then insert these values into the database in your way.
String Title = Dr [I] [ " Title " ]. Tostring ();
String Linkurl = Dr [I] [ " Link address " ]. Tostring ();
String Categoryname = Dr [I] [ " Category " ]. Tostring ();
String Customername = Dr [I] [ " Content Provider " ]. Tostring ();

// Response. Write ("<SCRIPT> alert ('imported content:" + ex. Message + "') </SCRIPT> ");
}
Response. Write ( " <SCRIPT> alert ('excle table imported successfully! '); </SCRIPT> " );
}

}

Public   Static System. Data. dataset excelsqlconnection ( String Filepath, String Tablename)
{
String Strcon =   " Provider = Microsoft. Jet. oledb.4.0; Data Source = "   + Filepath +   " ; Extended properties = 'excel 8.0; HDR = yes; IMEX = 1' " ;
Oledbconnection excelconn =   New Oledbconnection (strcon );
Try
{
String Strcom =   String . Format ( " Select * from [sheet1 $] " );
Excelconn. open ();
Oledbdataadapter mycommand =   New Oledbdataadapter (strcom, excelconn );
Dataset DS =   New Dataset ();
Mycommand. Fill (DS, " [ "   + Tablename +   " $] " );
Excelconn. Close ();
Return DS;
}
Catch
{
Excelconn. Close ();
Return   Null ;
}
}
# Endregion

 

 

The Excel format is as follows:
