Question

I am trying to read an excel file from a client’s PC. I am using an ASP fileupload control. When I am trying to read the file, its trying to open the file selected in the wrong folder. The file is located on the D: drive and it is trying to open it in the C: drive.

The following is what I am passing into a function:

    fpc.AddSpecs(ref model, this.fuSpecs.PostedFile.FileName.ToString());

The following is the connection string in the function:

        switch ( postedfile.Substring(postedfile.LastIndexOf('.') + 1) )
        {
            case "xls":
                connString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + postedfile + ";Extended Properties=\"Excel 8.0;HDR=NO;IMEX=1\"";
                break;
            case "xlsx":
                connString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + postedfile + ";Extended Properties=Excel 12.0;HDR=Yes;IMEX=2";
                break;
        }

What could be the problem?

Answer 1

1- Save the file on your server:

string uploadedFilePath = "URL" + System.IO.Path.GetFilename(fileUpload1.FileName));
fileUpload1.SaveAs(uploadedFilePath);

2- Assign the value of your connString variable:

switch ( postedfile.Substring(postedfile.LastIndexOf('.') + 1) )        
{            
    case "xls":                
        connString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + uploadedFilePath + ";Extended Properties=\"Excel 8.0;HDR=NO;IMEX=1\"";                
        break;            
    case "xlsx":                
        connString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + uploadedFilePath + ";Extended Properties=Excel 12.0;HDR=Yes;IMEX=2";                
        break;        
}
