c# - Path.Combine and File.Move with dot in file path -

considering below foreach loop:

foreach (fileinfo fileinfo in files) {     string filename = fileinfo.tostring();     filename = filename.split('_')[0]; // file suffix      string sqlstring = "select 'company-plc.' + ftpuser dbo.control brand = @filename;";     sqlconnection connection = new sqlconnection(conn);     sqlcommand cmd = new sqlcommand(sqlstring, connection);     cmd.parameters.addwithvalue("@filename", filename);      connection.open();     sqldatareader reader = cmd.executereader();      while (reader.read())     {         string destinationsuffix = reader[0].tostring();                             string fullpath = path.combine(destinationpath,destinationsuffix);          fullpath = path.combine(fullpath, fileinfo.fullname);          file.move(fileinfo.fullname,fullpath);                         }     reader.close(); } 

current fileinfo location: \\server\directory

original value of destinationpath = \\server\folder\folder

after sql query, destinationsuffix = company-plc.test

the file being moved fileinfo called test.csv.

current outcome:

file not moved, file .test extension created i.e.

\\server\directory\company-plc.test

desired outcome:

\\server\folder\folder\company-plc.test\test.csv

can see path.combine erring?

check documentation of path.combine - find if second parameter consists of full pathname - returned. try using fileinfo.name instead.

fullpath = path.combine(fullpath, fileinfo.name);
