Need help to write/read dictionary<string,object> to/from the file location.

Question

Hi Team,

Can i have any other new technique(provided by json library) to write/read the dictionary<string,object> from the json file path.

Currently i am doing the below..

string content = string.Empty;
string libraryPath = string.Empty;
Dictionary<string, object> _globalsetting = new Dictionary<string, object>();

_globalsetting[globalSetting.Key] = globalSetting.Data;(we are passing globalSetting)
content = JsonConvert.SerializeObject(_globalsetting);
libraryPath = UsersSettingsFileName;(path we are passing)

using (var sw = new StreamWriter(libraryPath,false))
{
                    sw.Write(content);
                    sw.Flush();
                    sw.Close();
}

Note : i dont want to use the streamwriter to write the data

Best Regards,

Sunil

Hi,@Sunil A M. Welcome Microsoft Q&A. If you prefer not to use StreamWriter, you could use File.WriteAllText method provided by the System.IO namespace.

File.WriteAllText is a convenient method provided by the System.IO namespace in .NET that simplifies the process of writing content to a file. It automatically handles file creation, opening, writing, and closing, so you don't need to manually create a StreamWriter and explicitly call Write or Flush as you were doing previously.

File.WriteAllText(libraryPath, content) will perform the same operation as StreamWriter.Write(content) in your code. Both methods will write the content to the file and overwrite the file if it already exists.

using Newtonsoft.Json;

using System.IO;


string libraryPath = UsersSettingsFileName; // file path

Dictionary<string, object> _globalsetting = new Dictionary<string, object>();

_globalsetting[globalSetting.Key] = globalSetting.Data; // Add data to the dictionary

string content = JsonConvert.SerializeObject(_globalsetting); // Serialize the dictionary to JSON

// Write the JSON content to the file (overwriting the file if it already exists)

File.WriteAllText(libraryPath, content);

Just use File class:

File.WriteAllText(libraryPath, content);
