SQLLDR in C#. please help

Question

I have used the code from below link:

http://www.dotnetspider.com/resources/3069-How-insert-e-data-from-excel-Database.aspx

It works well in my personal PC and i was able to insert all data from CSV to Oracle table.

But when i implement the same in my office machine. iam not getting any output or error message.

i get a cmd.exe window and it exists after few seconds. Nothing happens after this.

Looks like a permission problem. I am stuck, kindly help.

Is there any other possibility to execute sqlldr.exe directly?

It looks like there are no articles on this in C# corner. Somebody pls help.

Thanks in advance.
