I know this post is old but just in case someone comes with the same problem.

just use writer.Write() and pass to the Write function any object you want to write in the file.

For example, string myString = "Hello";

writer.Write(myString);

and then to load use: reader.ReadString();

You can find more info on the msdn (which is really good for standard libraries): https://docs.microsoft.com/es-es/dotnet/api/system.io.streamwriter?view=netframework-4.8 https://docs.microsoft.com/es-es/dotnet/api/system.io.streamreader?view=netframework-4.8
