how to save any file in specific folder in c# programatically

Question

I want to save my backup file in specific folder. currently I'm using a saveFileDialog box to give path and file name on a button click . But I want to create this backup by giving name as (DateTime.Today.Date.ToShortDateString()) and save this in "D:\\Database" directly on button click. and don't want to use saveFileDialog box. I'm using this code:

SqlCommand cmd = new SqlCommand("USE MASTER BACKUP DATABASE plproject TO DISK = '" + saveFileDialog1.FileName + "'", connectionsql);

Answer 1

I guess you are looking for this

public static void WriteAllText(
    string path,
    string contents
)

File.WriteAllText("D:\\DataBase\\"+DateTime.Today.Date.ToShortDateString(),YOURDATASTRING);

Note: It will overwrite any file with same name.

There are many other useful methods available in FILE class. You can check which suits you best.

EDIT 1

Try this

string fileName="D:\\Backup\\"+DateTime.Today.Date.ToShortDateString();
SqlCommand cmd = new SqlCommand("USE MASTER BACKUP DATABASE plproject TO DISK = '" + fileName + "'", connectionsql);
