Hi !

I have to use Excel from Diffrent Location not Fix Location.Like C:\Details.xls.

MSIL

string excelConnectionString = @"Provider=Microsoft.Jet.OLEDB.4.0; Data Source=C:\Details.xls;Extended Properties=""Excel 8.0;HDR=YES;""";

I am trying but not work ---
string FPath = "C:\Details.xls";

MSIL

string excelConnectionString = @"Provider=Microsoft.Jet.OLEDB.4.0; Data Source="+ FPath  +";Extended Properties=""Excel 8.0;HDR=YES;""";

Please Correct it.

As I am using Paramereized Code below, it is working Fine(Database path passing from TextBox) ---
string str = "INSERT INTO Test SELECT * FROM OPENROWSET('Microsoft.Jet.OLEDB.4.0','Excel 8.0;Database=" + txtPath.Text + "', 'SELECT * FROM [Details$]')";

@_Filename isn't going to work, this isn't a scripting language.
You should use ... Data Source =" + _FileName + ";Extended ... etc.
Maybe it's even necessary to put qoutes around your filename because it has space characters in it.

Solution 1

Shouldn't

string FPath = "C:\Details.xls";

be

string FPath = @"C:\Details.xls";

?

Cheers

Solution 3

Stick an '@' character in front of the double quotes:

string FPath = @"C:\Details.xls";

That stops the C# compiler assuming "\D" is a single escaped character...
