Hello thelist, I've used @ for escaping e.g string str1 = @"C:\folder\file.txt"; to convert it to C:\\folder\\file.txt I've notice a few SQL examples like: // query 1 string sql1 = @" select * from customers "; I'm puzzled by the use of @. Is it doing anything? -- Best regards, Arthur mailto:ArthurM at seipas.com
