My excel is Unicode delimited format file. so i will have to use CharacterSet=65001 to represent that file format . Warmming if you use CharacterSet=Unicode, you will see the data table will scremup in the debug window.

here is the solution

  string ConnectionString = string.Format(@"Provider=Microsoft.ACE.OLEDB.12.0; Data Source={0} ; 

Extended Properties=""Text; HDR=NO;FMT=Delimited; CharacterSet=65001;IMEX=1;"";", 

Excle File with absolute path);
