m trying to make connection with Excel. I have used many of connection string But no one is working.
**Connection String 1 Gives error-**The 'Microsoft.Jet.OLEDB.4.0' provider is not registered on the local machine.
Filepath="C:\"
1-var ConStr = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + Filepath + ";Extended Properties=Excel 8.0"
This Connection string Gives error string "Unspecified error"
2-var ConStr= "Provider=Microsoft.ACE.OLEDB.12.0;Data Source="+Filepath+";Extended Properties=\"Excel 12.0 Xml;HDR=Yes;IMEX=1;\"";
using (var conn = new OleDbConnection(ConStr)) { conn.Open(); }
How to Choose right Connection string?
