ExcelConnString = "Provider=Microsoft.Ace.OLEDB.12.0;Data Source=" + filePath + ";Mode=ReadWrite;Extended Properties=\"Excel 12.0 Xml;HDR=YES\""; 

DataTable DtSheetName = new DataTable();
                
   DtSheetName = oledbconn.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);

In DtSheetName i get the names of sheets in workbook.But also the names which i have renamed for example-'alert' sheet i have renamed to 'messeges'.So i should get only messeges in DtSheetName .But i am getting both alert and messeges.Is there any way to get rid of the renames sheet names?
