srkarthik_82 · January 10th, 2007, 09:30 PM

Hi,

   I am writting a textfile to c:/Temp folder.
   I want to check whether there is Temp folder available in c: , before i save the files
   in c:/Temp.If there is no folder called Temp in c:,then i want to create a new folder[Temp]
   dynamically.

   Can somebody give me an suggetion to do it????????

   My existing code is:

        public void TextWrite()
            {
                string logPath = (string) (new System.Configuration.AppSettingsReader()).GetValue ( "DataAccessLogPath", typeof(string));

     ////////////////////"DataAccessLogPath" is <add key="DataAccessLogPath" value="c:\Temp\"></add> given in App.Config file.

                DataTable dt= Context.QueryDataTable(Sql.Select( RootSystem.Bills.WOWJ_NO,
                RootSystem.Bills.AssetID,RootSystem.Bills.SuiteID, RootSystem.Bills.LeaseID,
                RootSystem.Bills.OrganizationID,RootSystem.Bills.O rganizationName,RootSystem.Bills.ContactID,
                RootSystem.Bills.Address,RootSystem.Bills.BatchID, RootSystem.Bills.ChargedDate )
                .Where(RootSystem.Bills.IsBilled==0));

            string BatchID="Bill"+DateTime.Now.Day.ToString()+DateTim e.Now.Month.ToString ()+DateTime.Now.Year.ToString () ;

                StringBuilder str = new StringBuilder();

                for(int i=0;i<=dt.Rows.Count - 1; i++)
                {
                    for(int j=0;j<=dt.Columns.Count - 1; j++)
                    {
                        if(dt.Columns[j].ColumnName.ToString ()=="BatchID")
                            str.Append(BatchID.ToString() + "\t");
                        else
                            str.Append(dt.Rows[i][j].ToString() + "\t");
                    }
                    str.Append("\r\n");
                }
                string filename=logPath+BatchID+".txt";
                StreamWriter writer = new StreamWriter(filename);
                writer.WriteLine(str.ToString());
                writer.Close();

hi srkarthik,

eg.

Code:

if (!Directory.Exists(@"C:/Temp"))
{
   Directory.CreateDirectory(@"C:/Temp");
}

or in your case Directory.Exists(logPath);

Just to be difficult:

srkarthik_82, I installed windows on the D: drive and I don't have a C: drive. Your program doesn't run.

If you want to work with temporary directories and files, use the methods provided by .NET for it:

Returns a unique temporary filename (also creates a zero-length file on the disk)

System.IO.Path.GetTempFileName()

Returns the path to the system's temporary folder

System.IO.Path.GetTempPath()

Yeah, I agree.

I was really answering:

The Folder location is stored in his app.config, and this enables the app to use any folder, which I think is a bonus.

However, if the required folder is not on the root drive the code will have to be amended to test and create all folder in the path.
