C# issue with oledb connection string for excel

Question

I receive a string like "c:\\test\\abc.xlsx" which indicates me the excel path. I have to depend on what i receive and cannot hard code it. Now what how should i make sure the the single "\\" is escaped and it becomes "\\"

string **PATH** = "c:\test\abc.xlsx"
string conn = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=**PATH**;Extended Properties=Excel 12.0;";

Answer 1

Should be simple:

String thePath = "c:\\test\\abc.xlsx"
String conn = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + thePath + ";Extended Properties=Excel 12.0;";

Answer 2

The single "\\" doesn't appear to be escaped properly.

Try: string path = @"c:\\test\\abc.xlsx";

The leading @ sign will escape it properly for you
