使用c＃将Excel数据导入asp.net中的数据表

Question

Is there any other way to import an Excel file data to a datatable and load it in Gridview in asp.net 2.0 using c#?

I tried using

OleDbConnection oconn = new OleDbConnection(@"Provider=Microsoft.ACE.OLEDB.12.0;Data Source="+path+";Extended Properties=Excel 12.0");

and it works in my local machine, but when i deployed it in network (server), it gives an error of

The 'microsoft.ace.oledb.12.0' provider is not registered on the local machine.

I know that I should install something to remove the error and make the web application work, but we are not allowed to install something in the server as it may affect other application integrated with it.

Any help please...

First go through following msdn thread and try to resolve issue.

If you do not want to install OLEDB provider on server, you should use .NET libraries to read/write Excel files. There are plenty of free libraries available like following. You can use one of these to populate collection or datatable to bind grid.

• Excel Data Reader
• NPOI
• Excel Package

You can download NPOI and Excel Package from CodePlex website
