I want to add several csv files to the project and use them as text resources. Well, to lay together in a folder for order. Create a folder no problem.

project context menu ➙ Add ➙ Create folder

Files are also created

folder context menu ➙ Add ➙ Create item Visual Visual C # elements ➙ Text file

But how to use their contents?

After adding a resource, you need to set in the designer the property Действия при сборке value of the Внедренный ресурс (naming in Russified Visual Studio, in English language will be Build Action and Embedded Resource ). To extract a text file, you will need to use the GetManifestResourceStream() method of the Assembly class, an instance of which the corresponding executable assembly can be obtained by the static Assembly.GetExecutingAssembly() method. Do not forget that to use Assembly you must enter using System.Reflection in the module header or refer to it System.Reflection.Assembly .

GetManifestResourceStream() returns a Stream . Knowing that we are dealing with text, either we read the System.IO.StreamReader entire file into an instance of string .

 using System.Reflection; using System.IO; ... public static string GetTextResource(string @namespace, string folder, string filename) { using (Stream stream = Assembly.GetExecutingAssembly().GetManifestResourceStream( $"{@namespace}.{folder}.{filename}")) { using (StreamReader sr = new StreamReader(stream)) { return sr.ReadToEnd(); } } }

Or we will organize other logic of reading the file.

    Use the resource mechanism.
    Go to the project properties, the "Resources" tab, add a new resource file (if you don’t have one yet), add a new or existing text file.
    After that, you can refer to this file as Properties.Resources.<Имя файла> .
    Those. if you added the main.csv file, you can access its contents as Properties.Resources.main . This will be a read-only line with the contents of the file.
