İmpersonator Connection

[Çağrı TÜRKER]

string pathToExcelFile = ""
+ @"C:\MyFolder\ProjectFolder\sample.xlsx";
string sheetName = "Sheet1";
var excelFile = new ExcelQueryFactory(pathToExcelFile);

this code is okey but if i changed the path impersonator like this "\file01server\uploads" doesnt work.
Are there any suggestion?
