Writing a JSON (or TXT) file in WPF C# -

i have been trying make sense of http://msdn.microsoft.com/en-us/library/sfezx97z.aspx uses savefiledialog, hard me understand. have following code:

fileinfo existingfile = new fileinfo("c:\\users\\cle1394\\desktop\\apple foreign tax payment sample layout proposed - sample data.xlsx");  consoleapplication2.program.exceldata data = consoleapplication2.program.getexceldata(existingfile);  var json = new javascriptserializer().serialize(data); 

how can output contents of json .json or .txt file?

i let user either see link/ button click download/ save file location on computer, or, display save file dialog box can save file location on computer.

edit (to let op comment on parts not clear):

savefiledialog savefiledialog1 = new savefiledialog(); savefiledialog1.showdialog(); if(savefiledialog1.filename != "") {    file.writealltext(savefiledialog1.filename,json);    } 

you looking this, then:

file.writealltext(@"c:\some\path\json.txt",json); 

and note save file using utf8-encoding without byte order mark. if need bom, need use file.writealltext(path, content, enconding);

see here.

update - adding sample savefiledialog:

 if(!string.isnullorempty(savefiledialog.filename))  {      //savefiledialog.filename should contain full path      //according documentation: http://msdn.microsoft.com/en-us/library/system.windows.forms.filedialog.filename.aspx      file.writealltext(savefiledialog.filename,json);   }
